How long does it take to adjust a wheel alignment? And when should it be done?

Adjusting the wheel alignment angles, or adjusting the wheel alignment, takes about an hour if there are no breakdowns in the suspension. If the vehicle has problems with the adjustment bolts and suspension components, the procedure can take up to two hours.

Wheel alignment is an essential procedure that will help you extend tire life, provide optimal braking, a comfortable ride, and improve safety on the highway. You should have your wheel alignment adjusted every 2 or 3 years or every time you have your vehicle's suspension and steering system serviced.

How long does it take to do a wheel alignment?

The issue of performance and normal functioning of the car is always in the first place for the owner. Signs will help you not to miss the moment when you need to do a wheel alignment, after which you should contact a service station. Manipulations performed using modern stands will prevent problems on the road and ensure comfort while traveling.

What is the effect of wheel alignment angles?

The controllability of a vehicle's suspension depends on two parameters: camber and toe. Wheel camber is measured in degrees. This is the angle between its central plane and the perpendicular to the surface of the roadway. The quality of travel and the reliability of traction on the surface depend on its correct setting.

The toe-in angle (toe-off) is calculated as the difference in distances, which are measured in the horizontal plane along the front and rear points of the wheel rims. The result is measured in millimeters, degrees or minutes.

• positive – the distance at the front points is less than at the rear;
• negative (reverse) – the distance measured from the front points is greater;
• zero – the vehicle’s wheels and tires are located parallel to each other.

Deviations in the positive and negative directions require correction. Otherwise, the tire treads will wear out quickly.

Another important parameter is caster, defined as the longitudinal inclination angle of the wheel turning axis. The parameter affects controllability. Exceeding its normal values ​​makes the steering “sharp”. A lower value causes the steering wheel to become heavy. Caster adjustment is carried out during the wheel alignment adjustment procedure.

What are the dangers of incorrect or “knocked down” adjustments?

A properly adjusted wheel alignment will save the car owner:

• from rapid and uneven wear of rubber;
• serious problems with vehicle controllability;
• expensive suspension repairs, including replacing broken wheel bearings.

In addition, if the adjustments are incorrect, the car begins to roll heavily when cornering, and during acceleration and driving in a straight line, other problems appear - from the “beating” of the steering wheel to the car moving to the side. All this creates a real safety threat not only for drivers and passengers of the vehicle, but also for all other road users.

Therefore, every car owner must regularly and very responsibly check the settings and adjust (if necessary) the wheel alignment in a car service center or, if you have certain skills, with your own hands.

How often should a wheel alignment be done?

So, three main parameters of the suspension are subject to adjustment, and they should be discussed in the theoretical part of the article.

Camber is the angle of the wheels relative to the road surface. It can be negative - if the upper part of the wheel is inclined towards the center of the car, and positive - if the upper part of the wheel is, accordingly, inclined from the center of the car. And each of the provisions has its own positive sides and disadvantages. For example, if the camber angle is negative, then the contact patch between the wheel and the road increases, traction improves, but the tires wear out faster.

The second important concept is caster - the angle of longitudinal inclination of the wheel's turning axis, or, more simply, the horizontal position of the wheels in the arches. This position affects handling: a slightly increased caster makes the steering sharper, but in the case of an excessively increased caster, the steering becomes heavy.

The third concept to know is toe-in. Total toe is the sum of all angles between the longitudinal axis of the car and the plane passing through the center of the left and right wheels. Toe can be positive (for the front wheels) - in this case, the car becomes more stable at high speeds, but at the same time understeer increases. Negative toe-in of the front wheels makes steering more precise, but at the same time, tire wear increases and all road irregularities respond to the steering wheel - the so-called “beating” appears.

How is the procedure itself carried out? It is carried out differently in different workshops. Some experts approach the matter more responsibly: before adjusting the wheel alignment, the specialist first checks the pressure in the wheels, usually using a portable compressor for this. Next, sensors are installed on all wheels, and the foot brake is clamped using a special spacer. Particularly qualified technicians also inspect the suspension for visible faults - however, such specialists are extremely rare. The car is “driven into a pit” and “pressed”. Data from the sensors is transmitted to the computer, after which the results are entered into a table, with the first line showing the performance of the car with cargo in the trunk, the next line without it. This is because even a small additional weight can affect the measurement results. However, most service workshops usually omit this point and take measurements with the vehicle loaded.

The two most common reasons why motorists come to get a wheel alignment are poor handling or the car pulls to the side, or increased tire wear.

However, the wheel alignment should also be checked and adjusted on a new car. The manufacturer sets average parameters with the expectation that the dealer will prepare the car and make the necessary adjustments before selling it. But, as practice shows, sellers mostly omit this point.

Manufacturers recommend performing this procedure every 15-20 thousand kilometers, that is, approximately a couple of times a year. In order not to waste money, you should adjust the wheel alignment after a seasonal change of tires.

There are other situations in which the wheel alignment should be adjusted. Firstly, after some repair work: replacement of ends, ball joints, steering rods, steering gear or rack, pendulum arm, struts, springs and silent blocks. Secondly, under certain behavior of the car - for example, if the car pulls to the side and the steering wheel is crooked, or if the car begins to “swim” in a rut, or if it is delayed in steering. Thirdly, the wheel alignment must be done after changing the ride height of the car (usually this is done using special stands or thick rubber bands that are installed under the suspension springs). And finally, fourthly, a wheel alignment should be done if the steering wheel stops “returning” when exiting a turn, or if the car has a different turning radius to the left and right.

So, a wheel alignment should be done when the car has poor handling, increased tire wear, after some repair work related to the suspension, as well as after each wheel re-alignment or installation of new tires. In this case, the technician should first inspect the car’s suspension, ask the driver about the loads in the trunk and, if they are heavy, remove them while making adjustments. The specialist should also check the air pressure in the wheels, diagnose the free play of the steering wheel and inspect the wheel rims for deformation. Failure to follow any of these procedures may affect sensor performance.

What it is

First, let's figure out what is hidden under the term “wheel alignment.” Most often, both of these parameters are combined, since they are jointly responsible for the correct position of the vehicle’s wheels. However, in fact, these are not even two, but three completely different settings, the frequency of which depends on the operating conditions of the car:

1. Camber is responsible for maximum adhesion of the tire to the road surface while the vehicle is moving and for the stability of the car in corners. The angle between the vertical and the plane of rotation of the wheel in a modern passenger car tends to zero (the wheels are perpendicular to the road). However, sports cars often have negative camber (the tops of the car's wheels point inward relative to the perpendicular axis) for better cornering control, while trucks often have positive camber (the tops of the wheels point outward) for better handling when fully loaded. This characteristic can change automatically when driving with a load and changing the vehicle's roll.
2. Toe-in - the rate of tire wear largely depends on this parameter. Shows the angle between the direction of movement of the car and the plane of rotation of the wheels located on the same axis.
3. Castr (caster or castor) - is responsible for the automatic alignment of the wheels when exiting a turn, which occurs due to the speed of the car. Determined by the angle between the vertical and the projection of the longitudinal inclination of the wheel during a turn.

When do you need to adjust toe and camber?

Adjustment of the RS can be planned or unscheduled. In the planned version, its regularity depends on the recommendations of the vehicle manufacturer. Domestic cars need a procedure every 10-15 thousand kilometers. Foreign vehicles should be shown to service station technicians after 30 thousand kilometers. When answering the question of how often to do a wheel alignment, experts advise contacting the service at least once a year. The best time is spring, when replacing winter tires.

Unscheduled adjustment procedures may be needed in the following cases:

• accelerated tire wear or tire replacement;
• spontaneous deviation of the car to the side while driving on the highway;
• side impact of the wheel on an obstacle, which causes a dent on the disk;
• replacement of chassis parts (shock absorbers, suspension arms, silent blocks and other elements);
• changing ground clearance parameters (shortening or lengthening springs);
• after a long drive on roads without high-quality surfaces;
• aggressive driving style.

Result of wheel alignment adjustment:

• increasing vehicle stability;
• improved handling;
• minimal risk of skidding;
• fuel economy;
• reduced tire wear.

In what cases is wheel alignment adjusted?

Wheel alignment angles must be adjusted:

• after repair of the chassis;
• if work was carried out as a result of which the ground clearance of the car changed (spacers were installed, suspension springs that differed from the standard ones, shock absorbers were replaced, etc.);
• if a car moving in a straight line “goes” to the side, the steering wheel “pulls” to the right, left, or if the car deviates from the desired direction, it does not hold the road;
• with a poor reaction to steering wheel rotation (late, the steering wheel is tight, or, on the contrary, too light);
• if, with a working brake system, at the moment of braking the car pulls to the side or turns around on a slippery surface;
• after hitting potholes or obstacles at high speed, if the rims were bent or the suspension was damaged;
• if car tires wear out too quickly or unevenly;
• if, when turning left and right, the radius along which the car moves is different;
• if, at the exit from a turn, the steering wheel returns too slowly to its original position or does not return at all;
• after a scheduled or seasonal tire change.

It is also recommended to carry out adjustments for recently purchased used cars, after completing the break-in of new cars. In addition, the procedure must be repeated at certain intervals - at least once every 15 thousand km (or less if the car is driven mainly on rough roads, the driving style is aggressive, etc.).

"Autocenter 37" performs wheel alignment for front- and rear-wheel drive vehicles. A modern computer stand is used for measurements. Compensation for disc runout can be done by rolling or in the traditional way, by lifting the car. From us you can order a wheel alignment service at an affordable price and with a guarantee of quality and high accuracy of adjustments.

A clear example of how alignment affects the position of the wheels on a car

Let's look at another interesting example, which concerns the care of car tires. A fairly detailed foreign video will help us study the material. Don't worry, we'll give you a translation of the main points:

The 1st minute of the video shows and describes how wheel camber affects the handling of a car. In this case, negative. Typically used by sports car manufacturers, it makes it easier for them to turn into corners at high speeds by actively resisting tire deformation and increasing friction.

More “civilian” camber options are more concerned about the safety of tires and rolling.

The 2nd minute of the video visualizes the so-called castor - the angle of longitudinal inclination of the steering axis of the car wheel. In other words, this is wheel runout, exactly the same as on bicycles or motorcycles. They simply see this better using the example of a fork.

The castor setting is a sports setting and is not used on regular cars.

The 3rd minute of the video shows the wheel alignment. The smaller the toe-in, the less tire wear. However, when driving, the driver involuntarily makes small movements with the steering wheel. These mini-steers should not affect straight-line movement, which the toe-in handles perfectly.

What is wheel alignment and can you do it yourself?

Negative camber improves vehicle stability, but only if you are entering a corner at high speed or in a controlled drift. But when driving in all other modes, this only worsens the level of grip of the wheels and road surface. This happens because the contact area between the tire and asphalt is reduced.

Every driver has at least once experienced uncomfortable movement associated with deterioration in controllability. For example, a car spontaneously deviates from a given trajectory and does not want to drive in a straight line. There may be several reasons for this: different pressures in the tires installed on the right and left sides of the car, or incorrectly installed wheel alignment.

Why do you need to do geometry when replacing components and parts of the chassis?

The position of the car wheels depends on the positioning of the chassis parts. For example, when replacing a ball joint, rod, rack, or zero tip, the gap between the parts changes. This leads to the appearance of an angle of inclination of the tires relative to the horizontal plane. The previous settings also fail when changing the shock absorbing spring or tires, since the installation angle depends on the ground clearance.

Replacing chassis components may result in the steering wheel being in the wrong position. In this case, driving the car is prohibited, since its body may spontaneously move to the side while driving. Any malfunction requires correction, and an experienced driver determines the need to adjust the wheel alignment after manipulating the chassis by the behavior of the car on the road.

Always be in the Mood

Previously, a special ruler for adjusting toe was popular among garage mechanics. It is still used in some places - it is convenient and does not require special skills. This line was also popular because it could be made from whatever was at hand.

Every car owner knows that any work on the car’s chassis entails changes in the correct wheel alignment angles. As a result, the way the car behaves on the road changes. Wheel alignment parameters also depend on a host of other factors. This is tire pressure, the level of tire wear, play in the suspension and chassis of the car. To ensure stability and controllability, the front wheels in the car are set at certain angles relative to the body and suspension. Let's find out what it is - wheel alignment - and how to do it.

Wheel alignment: what are the parameters and when to do it

Toe-in is another angle of the wheels, calculated by the ratio of the vertical to the plane of the car body. Many people are wondering whether wheel alignment is done on the rear wheels. In most cases, it is adjustable from the front and back. This parameter can be measured in degrees and millimeters.

• in the first case, the angle of the wheels relative to the road surface is zero, the wheels are exactly perpendicular to the road surface;
• in the second case, the angle is acute - the upper zone of the tire is directed inward;
• in the third case, the angle is obtuse - the upper zone of the tire is directed outward.

Measuring individual wheel alignment

To measure the toe-in of each wheel, it is necessary to create a corridor consisting of two parallel lines. To create them, you can use strong threads, fishing elastic bands, and laser beams. The lines must run strictly horizontally; they must be aligned to the height of the wheel centers. A basic corridor can be created in three ways:

• The first is to attach the threads directly to the wheels. This is the simplest, but least accurate method. The wheels may have different offsets relative to the arches, which disrupts the parallelism of the lines.
• The second is fixing the threads on stationary supporting structures. The method is more accurate in comparison with the previous one, but it is inconvenient because during the process of adjustments and rolling the car, the chassis may shift relative to the constructed lines.
• The third is to create a corridor around the car body using rack and pinion fastenings. The slats are fixed in the front and rear of the car, strictly in the centers of the wheels.

There are many examples of such constructions on the English-language Internet. For example, type “BG rasing string lines kit” in the search.

The corridor around the car body is made of river fasteners.

In garage conditions, it is appropriate to use the most budget-friendly and simplest method. To measure alignment and camber, you will need two aluminum slats, which can be purchased at any hardware store. One of them needs to be placed on the floor near the rear or front axle of the car. Next, you need to make marks on the rack at a short distance from the wheels - about 5 cm. Then the distance between the marks is determined, the resulting value will be the width of the measuring corridor. By dividing this parameter in half, you can calculate the location of the midline. Next, you need to attach a second strip to the marked tube and transfer the resulting marks to it.

Setting marks on aluminum tubes.

Two additional marks are applied to the car’s bumper exactly in the center. They are set using a tape measure and marked with a piece of electrical tape or masking tape.

Installing a tag on a car bumper.

Aluminum tubes are fixed using ordinary office clothespins. They are attached to bumpers, mudguards or other body elements, depending on the design features of the car.

Next, you need to tighten rubber cords on the slats in the previously marked places, which can be purchased at any fishing store. Instead, you can use non-elastic threads, which can be secured to the tubes with rubber bands for money. This will avoid breaking the threads, ensure the necessary tension and minimize the error in determining the wheel toe angles.

Fastening rubber cords to aluminum tubes.

At the next stage, the measuring corridor is centered along the marks that were previously marked on the bumpers. Next, you need to set the steering wheel to the zero position; for greater accuracy, you can use a building level.

Setting the steering wheel to the zero position.

After the above steps, you can already detect the lateral displacement of the wheels. To do this, measure the distances from the centers of the hubs to the threads of the base corridor and determine the difference between them. This is relevant for drivers in whose cars the wheels extend out of the arches at different distances.

Measuring the distance from the centers of the hubs to the threads of the base corridor.

Now you can start measuring the individual alignment of each wheel. Measurements are carried out by determining the distances from the lines of the base corridor to the symmetrical points of the rim of the discs in front and behind the center of the wheel. The results obtained must be recorded in a notebook or, in the absence of one, written down with chalk on the asphalt in the garage.

Determination of distances from the lines of the base corridor to the symmetrical points of the rim of the disks.

Then you need to roll the car forward or backward half a revolution of the wheel without changing the position of the lines of the measuring corridor. It is important that the steering wheel remains in the same position. Next, you need to take repeated measurements of the individual wheel alignment several times. If there are no significant differences between two measurements, they can be accepted as true. If the difference is significant, you should roll the car a few tens of centimeters more and find “crooked” wheels. This way we calculate the wheel curves. To compensate for wheel runout during calculations, we find the most frequently repeated values ​​of individual toe-in alignments.

To convert millimeters to degrees and minutes, we use the table below.

Table for converting millimeters of individual wheel toe into degrees and minutes.

When all half-toe angles have been determined with sufficient accuracy, the steering angle of the rear axle can be calculated. The presence of such an angle may be indicated by differences in the parameters of the semi-convergence of the rear wheels relative to the center line.

If adjustment of the rear wheels is not planned, you can reorient the base corridor along the trust line laid through the rear axle. To do this, you need to move the fixed slats so that the semi-convergence of the rear wheels is aligned with the new position of the corridor. Then you will need to adjust the position of the front wheels according to it, fixing the car’s steering wheel strictly in the center. Thus, the car will drive slightly sideways, but the driver will not notice it.

When determining the parameters of semi-toe-in, it is necessary to take into account the total toe-in of the wheels on the axles (on the front and rear axles), which consists of individual angles taking into account their signs. It is this indicator that determines whether the tires will wear out evenly and how controllable the car will be while driving. To find out the optimal value of overall toe for a specific car model, you should study reference materials that contain the manufacturer’s recommendations.

Types of equipment

To adjust the wheel alignment, you should contact a car service center. Craftsmen have special stands at their disposal that allow them to detect gaps invisible to the eye and perform the necessary adjustments.

Wheel alignment adjustment stands are special machines whose main task is to determine the angle of inclination of car wheels and set it if they are in an incorrect position.

Based on the principle of operation, the devices are divided into several types:

1. Optical. The very first units for adjusting RS. The research process on them takes a lot of time, and errors are possible.
2. Laser. A variety of optical equipment. Angles are measured using a laser beam.
3. Computer. Modern high-precision equipment, in which electronic computing devices are engaged in collecting and processing information. 3D stands create a three-dimensional projection of the vehicle. They help perform diagnostic and adjustment work as accurately and quickly as possible.

Optical stand

An optical bench uses light beams for measurements. They come from special tubes placed on the wheel rims. During measurements, a light beam is projected onto a screen with linear and angular scales. Experts compare the readings taken with the standards.

Such equipment is considered obsolete. Among its advantages are durability and low maintenance. However, it is not found in modern service stations.

Laser equipment

According to the principle of operation, such stands are similar to optical units. However, the source of measurement is a directed laser beam.

The operation of the system is organized simply:

• Laser emitters are installed on the car at the same distance from each other and in relation to the measurement scales;
• mirrors are mounted on the tires (parallel to the plane of rotation), opposite which measuring scales are installed;
• laser beams are calibrated so that their line of passage runs parallel to the wheel plane;
• the beam reflected from the mirrors must return to the starting point (this is the zero scale division);
• if there are deviations, it will fall higher or lower, which will show the magnitude of the error.

The stands are distinguished by accurate measurements and allow you to simultaneously calibrate all the wheels of the car. However, one study takes about an hour, since the adjustment of mirrors and laser generators is carried out manually. This requires skill and experience of specialists. When work is performed by an incompetent mechanic, errors may occur.

Computer systems

Stands based on electronic computers operate using sensors that are fixed on the measuring heads of the equipment. Located on wheels, the sensors accurately record their position in space and transmit this information to the computer. After processing it, the system produces graphs, reports and evaluation charts.

90% of the stands of modern service stations are computer-based. They can vary in design, the way they transmit information, and the electronics that make the measurements.

How long does it take to do a wheel alignment?

Car lovers often think about the proper performance of their vehicle, and this is no coincidence, because this factor is directly related to the service life. Car owners are often interested in the question: when is it necessary to do a wheel alignment? There is a lot of advice and disagreement here. Let's try to look at this situation in more detail.

Most service stations analyze vehicle data with negligence because it makes their job easier. It is often not taken into account that a car in which the trunk is often loaded behaves differently. Here it is necessary to carry out tests both in a light position and with increasing load. Another important indicator of a car’s performance is the level of pressure in the wheels, however, even here, mechanics often leave things to chance.

When you call a service technician, make sure they check your wheels thoroughly and follow all the procedures.

After what time is it time to think about the collapse of the assembly?

This type of procedure is best done when there are obvious deficiencies in driving the car (that is, the car often pulls to the side), when replacing important components, as well as when driving on poor road surfaces, and of course in cases in which a significant mileage has accumulated no maintenance.

Responsible car enthusiasts often ask mechanics: how long does it take to do the wheel alignment? To which they receive the answer that once every six months, or even more often. It is no secret that the number of visits a motorist makes to a workshop increases the income of maintenance technicians.

If you ask the same question in a showroom where they sell cars, they will probably tell you that a wheel alignment is done once every few years, because in this way the seller shows the strengths of the car and talks about the minimum costs for the car. Therefore, every driver must look after his car himself. After all, only he can clearly understand how the car behaves, whether the wheels move from side to side, what mileage has been generated, and what type of roads the car had to drive on.

The vehicle itself will tell you how long it is time to perform the wheel alignment, although you can test the integrity of its parts once every six months.

Main characteristics

–>

One of the frequent reasons for motorists to contact the workshop is to perform a wheel alignment. The reasons and situations when it is necessary to do a wheel alignment can be varied, but it definitely must be done efficiently, otherwise the driver risks encountering a lot of adverse consequences, including premature tire wear, poor handling, etc. The vast majority of car owners trust this type of work to professionals, but you can try to do it yourself. True, for this you need to know the correct sequence of actions and some important nuances.

The main rules to understand when wheel alignment is required

1. When you buy a car, the mechanics at the service station inside the store are required to perform a wheel alignment, but in reality this is not always the case. Often this type of procedure is performed in separate salons, because of this, people sometimes turn to other service stations. It is better to find out about this point in advance, perhaps it is even better to come to the salon, precisely in order to gain control over this process.
2. When tires are changed on wheels, it is recommended to check the alignment. But here it’s worth understanding that checking and doing are two different things, because a car can be in excellent condition.
3. If you understand from your driving style that one of the wheels is pulling to the side, then you need to check the wheel design. This is the most forced measure, which obviously requires wheel alignment. You should also check yourself to see how the steering wheel works without holding it. This way you will understand which direction your car is being driven.
4. When it is necessary to do a wheel alignment, it is also clear when the tires on the car are worn out. If you feel that a replacement is about to be needed, then this parameter of the car needs to be checked.
5. Let's say you still have a maintenance guarantee, then you must be informed about the timing of the wheel alignment check. As a rule, the mileage will be from 15 to 20 thousand km.

How long does it take to get a wheel alignment?

It takes an average of half an hour to adjust the wheel alignment. The duration can fluctuate up or down, it all depends on the car itself - what condition it is in, and on the car service - who works in it and on what equipment.

On average, the wheel alignment procedure takes at least 30 minutes, assuming that everything turns easily and is not rusty. But is it also possible to take into account a car from the street and consider its condition as average, then in the area of ​​an hour this will be considered the norm.

When I was studying, we were told in lectures about wheel alignment, today they increasingly say: wheel alignment.

How long does a wheel alignment take?

Please indicate your contacts and we will contact you within a few minutes. Wheel alignment and camber in relation to each other are two different suspension parameters that have the same adjustment goal, which is to improve the driving performance of the car.

Deciding on the wording

Wheel camber indicator

The camber angle is the angle formed by the rotating plane of the wheel and its conventional vertical.

The value of this indicator determines what position the car’s wheels will be in when cornering, and, accordingly, how clearly the car will take the turn.

There are negative and positive values ​​of this indicator: in the first case, the upper plane of the wheel is internal relative to the plane of its rotation, in the second case, it will be located on the outside.

Wheel alignment indicator

The wheel toe angle indicator is defined as the value between the vector of the direction of movement of the car (when viewed from above) and the plane in which the wheels rotate. This value will determine how controllable and stable the vehicle is on the road.

The inclination of the wheels “inward” of the car body (if we consider the projection of the car from above) is called positive toe, and outward - negative.

Custer

Another characteristic of the position of the car’s wheels is caster, which is the angle between the shock absorber in the MacPherson strut suspension and the inclination of the wheel knuckle.

. Caster is also defined as the inclined angle of the steering axis of the wheel. Drawing an analogy with the front wheel of a bicycle, this is the angle of the steering fork: the more the fork “lies”, the more the bicycle handlebar will tend to take a “straight” position.

Most car models are designed in such a way that the caster is 6 degrees and cannot be adjusted, so further we will only consider working with wheel alignment.

The importance of the correct position of the car wheels

Adjusting wheel alignment and camber is very important. A number of characteristics of the car will depend on how correctly the position of the car’s wheels is adjusted:

• the vehicle's resistance to skidding and overturning while driving;
• vehicle maneuverability and controllability;
• efficiency in terms of fuel consumption;
• car tire resource.

The position of the car wheels changes if:

• repair operations were performed that affected the suspension or steering system of the vehicle;
• the car on the road “caught” a hole, as a result of which the disk was deformed;
• the car received a strong blow;
• the car moved for a long time on an uneven road;
• the rods and steering tips have become unusable;
• the play of the longitudinal and transverse rods and the silent blocks of the levers has increased;
• the bridge is bent (in the case of models with a continuous bridge);
• the wheel bearing is worn out;
• the ball joint of the steering knuckle is faulty;
• The shock absorber support in the body cup is faulty.

Signs of wheel alignment problems

The technical manual for the car model, as a rule, indicates after how many kilometers it is recommended to carry out routine diagnostics of camber and toe indicators.

But in practice, this figure becomes very arbitrary, since the car can be used in different conditions. Therefore , in order to determine the need for diagnostics, you should be guided by the following signs:

• if the wheels are in a straight position, the steering crossbar remains shifted to any side from the horizontal;
• on a straight, level section of the road, if you let go of the steering wheel, the car goes to the side;
• on a straight course the car “yaws” and behaves unstable;
• turning the steering wheel is processed late;
• the steering is too unyielding (“stiff steering wheel”);
• with serviceable brakes, the car skids to the side when the speed drops sharply;
• on long turning radii, the wheels touch the fender liners;
• the steering wheel does not return to its normal position when the car completes a turning maneuver;
• while the car is moving, the tires rustle uncharacteristically;
• car tires wear unevenly (provided that the pressure in them is maintained within the required limits).

What is a car loan

The concept of a car loan is practically no different from a regular loan. This is money that a bank can provide for the purchase of a used or new car. In order to have a guarantee of payment of the amount on time, a car is taken as collateral, which implies the impossibility of reselling it. You should not rely on the bank's work without receiving benefits for yourself. Usually the payment is interest and commissions, which constitute profit for the credit institution, so if an advertisement talks about installment plans without extra expenses, you should not hope that this will bypass you.

When receiving a loan, the bank will take a small percentage for its work, so in order to avoid receiving a fine, you must make payments on time.

Making adjustments yourself

Preparing for measurements and subsequent adjustments

To carry out independent work on adjusting the angles of the vehicle wheels, you will need the most flat horizontal platform equipped with an inspection hole. You also need to prepare the following tools and auxiliary equipment:

• driver's tool kit;
• a plumb cord or building level, a piece of chalk;
• folding measuring ruler or tape measure;
• a skein of strong rope or flexible wire;
• two timbers with a flat surface, 60 cm long;
• two sliding supports for car wheels (can be made from 4 metal plates, lubricating each pair of plates with grease to ensure the best sliding).

The presence of sliding supports is extremely important for the adjustment operation, since the second wheel must be stationary during adjustment!

It is also better to perform suspension diagnostics before adjusting the wheel alignment angles.

The machine is installed on sliding supports placed at the same level. At this stage, it is extremely important to make sure that the machine is standing on a completely flat surface, otherwise the measurements will be carried out with a significant error, which is unacceptable. The steering wheel of the car should be level; the best solution would be to fix it. Set the car to the parking brake.

Camber

As a rule, the need to adjust the camber of the front wheels arises in cars with multi-link suspension.

If the indicator is unsatisfactory, the wheel position should be adjusted using keys and adjusting mechanisms.

Alignment: working with the front axle

For the front wheels, the toe-in values ​​are adjusted by adjusting the lengths of the steering rods. Changing the steering rods is carried out by rotating the steering tip and clutch.

The second method is to measure the distance from the stretched string to the wheel.

Normal toe-in for passenger cars is on average 0 - 0.25 degrees, which for each wheel will be 0-1 mm.

To make the adjustment, loosen the locknut and, by rotating the steering rod, you need to set the required distance, which will be the required angle.

Alignment: working with the rear axle

The toe-in of the rear wheels can only be adjusted if the car model is equipped with an independent rear suspension. The wheels are adjusted by adjusting the traction distance with eccentric bolts, or by rotating the couplings for the same purpose. The toe-in of the rear wheels should be 0-0.5 degrees.

Finishing setup

After all the manipulations have been completed and the camber and toe angles have been adjusted, it is imperative to move the car one meter back and forth. The purpose of this technological operation is to relieve possible stress in the suspension system and car tires. After this, you need to re-install the car in a horizontal position, secure the steering wheel, activate the parking brake and perform all control measurements. If the indicators remain unchanged or “float” slightly, while remaining within the normal range, the work is done.

Correction of toe-in and camber indicators using special equipment

The first stand on which adjustments were made to the angles of car wheels was introduced in the USA by auto design engineer Lee Hunter. It was called optical because it used focused beams to determine the angles of the wheels. In 1969, the stand was switched to computer technology, and a quarter of a century later, the optical stand was replaced by 3D technology.

An important role in the setup process is played by the experience and qualifications of the specialist performing the setup.

Often, “manual” skilled performance of work turns out to be of much higher quality than the use of “smart” equipment.

So, it is quite possible to adjust the wheel alignment of car wheels with your own hands. But if you are not too confident in your abilities, or have an expensive car with expensive tires, it is better, after setting it up yourself, to turn to professionals who can perform high-quality diagnostics.
