Owners are reminded of the poor quality of the road surface by periodic impacts on the steering rack. Despite systematic repairs and preventative maintenance, hard work days still have a negative impact. Mechanism wear is typical for both domestic and foreign automotive industries. After all, there are no perfectly smooth roads anywhere, some are worse, some are better.

If it is not possible to avoid a breakdown, you should postpone the onset of the breakdown as much as possible. This can be done by strictly observing the technical inspection deadlines. As a general rule, you should maintain a calm and relaxed driving style. A breakdown has occurred and the steering rack bushing has become unusable, so let's read below how to replace it.

In what cases is the steering rack bushing replaced?

The list of cases of replacing steering rack bushings is extensive; there is no point in listing all the points, since not all of them are important. The following are considered universal, “suitable” for any technical means:

• the steering wheel turns rigidly when turning the car;
• the level of hydraulics (fluid) in the power steering expansion tank systematically decreases;
• there is a game in the steering wheel;
• a knocking sound is clearly audible when driving over uneven surfaces;
• The power steering hydraulic pump hums abnormally, makes noise, and in general the sound of operation has changed.

Replacement procedure

Note for the driver: Despite the simplicity of the design and the simple principle of operation of the steering, in order to avoid breakdowns, it is recommended to carry out servicing only in service centers.

There are two possible repair options: replacing the steering rack bushing without removing the rack and with its complete disassembly. In each case, the technician individually makes a decision based on the results of vehicle diagnostics. The design of a technical device also influences the decision-making process. Some car models do not allow repairs without complete disassembly, especially Japanese brands.

If visual diagnosis reveals damage to a part of the body, then complete dismantling is unconditional.

The replacement mechanism is as follows:

1. Using a lifting mechanism, the car is raised to a comfortable height.
2. The technician unscrews the standard fastenings of the body part, hydraulic hoses, steering ends, and disassembles the rack as a whole.
3. Using a stationary vice, the master removes all components, including the steering rack support sleeve.
4. Run the seat troubleshooter, clean out the old grease, wash the parts.
5. Start reassembling in reverse order, taking into account the installation of new components.

At the end of the work, the mechanism is sent for diagnostics - a high-pressure support to check its functionality. The car is being prepared for delivery to the customer.

Replacing the bushing without removing the steering rack is carried out according to an abbreviated algorithm, but this method has not gained popularity; few people practice it.

Clamping bushings and their dimensional characteristics

The part is located on the driver's side and is subject to adjustment. The main task performed: the clamping sleeve presses the shaft, while the horizontal shaft can move freely in the housing area. Longitudinal and transverse directions are excluded. The formation of a gap can be eliminated. On many forums, there is a widespread opinion among drivers that in this small part itself, no processes take place. But is this really so? Not really.

Need for repairs

The part must be repaired immediately if certain problems are observed in its operation or appearance:

• Scuffs on the coating, formation of damage in places of contact.
• Loss of ability to hold the shaft in a vertical direction. With such a malfunction, the ability to perform the necessary functions is lost.
• When the bushing moves up and down, a characteristic knock is produced.

Malfunctions

1. The occurrence of roller play on the axis.
2. The roller surface wears out. Small areas of corrosion can be found on such a bushing.
3. The next malfunction most likely has nothing to do with the bushing itself, but with a related element called the horizontal shaft. The fact is that during operation, the edges of the roller form tracks on the shaft.

If you replace the element, you can solve the first two problems.

But the worn parts of the shaft do not allow it to come into contact even with a new element, so the only correct solution is to replace it with a pressure bushing that works on the sliding principle.

As a result, you can get rid of not only the first two, but also other problems.

The size of the part is as follows: the internal diameter is 24.55 mm, and the external diameter is 38.2 mm. Total length – 29.0 mm.

Types of bushings for installation on the control mechanism

• bronze: the best material available today, however it requires a perfect and uniform cylindrical base. Not all manufacturers provide similar features;
• fluoroplastic: a good anti-friction material, but when systematically exposed to high temperatures it is subject to deformation without recovery;
• caprolon bushing - has average wear resistance and friction strength, but due to its budget cost and appropriate quality, it is in demand on the market. Due to a certain plasticity of the material, parts must be processed with high precision. This is only possible in a factory, which reduces the level of skill;
• polyethylene rephthalate, also known as TEKAPET: this material is used for the manufacture of premium cars due to its high technical characteristics.

The article does not mention an electric drive mechanism. There is essentially no difference when replacing a steering rack bushing or other component. After reading the tips, we decided to try to fix the problem ourselves - try, but be extremely careful and attentive.

A properly functioning steering mechanism is one of the main conditions for ensuring the safe movement of any vehicle. If the owner of a Lada Kalina detects suspicious signs of failure of any of the components of this unit, he must urgently take effective measures to find and eliminate the malfunction. The main characteristic sign of a malfunction is knocking. It can be clearly heard when driving over uneven surfaces or when turning the steering wheel while driving. When the owner determines that the steering rack requires steering rack repair, he has two options: go to a service station to see a specialist or decide to repair the steering rack himself. You can make a replacement yourself, of course, it is not easy and problematic, but, nevertheless, it can be done. Also, if you have a repair kit on hand.

Description

Steering rack bushings for Lada Kalina

Do you want to forget FOREVER about any problems with the steering rack? We have found a unique solution! Caprolon bushings will allow you to simply and most rationally deal once and for all with the problems of steering rack failure on a Lada Kalina.

The most wear-prone component of the steering rack design is the support bushing. In the vast majority of cases (according to statistics - 95%), the steering rack needs to be replaced due to destruction of the support sleeve.

We offer an amazing alternative to bushing replacement that solves the problem FOREVER! For only 980 rubles!

In most car services where you go with such a problem, they will tell you that a complete replacement of the steering rack is necessary - fiddling with its repair is troublesome, time-consuming and not profitable for the service budget.

How much does a steering rack cost for Kalina Granta (VAZ-2190) and VAZ-2110 cars? - within 4,000 -10,000 rubles, not taking into account the cost of installation work.

Installing a new steering rack will certainly help you forget about all the problems with this unit for a while. After a certain period of time, the situation will repeat itself again, and again there will be a need to buy a new steering rack. Don't you think this is irrational? Then we offer an effective way out of this vicious circle - a bushing made of graphite-filled caprolon. Its installation on the Lada Kalina steering rack will allow you to forget what steering play or extraneous sounds when driving are.

Caprolon is a common material from which bushings and pulleys are made in various mechanical components. Caprolon is a polymer antifriction material, recommended for use in units with high friction. This material has a low degree of wear and a high percentage of resistance to friction when working with metal elements.

What are the advantages of installing a caprolon steering rack bushing?

• The steering rack problem will be solved once and for all.
• Saving money. You are guaranteed to receive savings of 2500-7500 rubles for one replacement of the steering wheel. Multiply this figure by the number of replacements you will make over the entire life of the car. Decent savings, agree!
• Impeccable level of quality. The original bushings wear out quickly because they are made of plastic. The technical characteristics of caprolon and the experience of scientific specialists who worked in conjunction with qualified Lada Kalina repair technicians made it possible to develop a high-quality product that works effectively throughout the entire life of your car.
• Providing excellent vehicle handling, familiar comfort and absolute steering control.

Design features

The Lada Kalina guide unit includes:

• electric amplifier;
• rudder column, adjustable for extension and tilt;
• rack with electric power steering with a mechanism for changing the gear ratio;
• rods with swinging tips and levers.

The mechanism is based on a mechanical gearing unit, in which the main active element is a helical gear, in which the pitch of the teeth varies depending on the length of the rack.

The figure shows the design of the Lada Kalina rack and pinion assembly.

Fixation in the rack-and-pinion pair is carried out using a spring, and a real plastic insert is adapted to reduce friction. The degree of compression of the spring element is adjusted with a nut. The factory distance between the steering shaft and the rack in the LADA Kalina model is 0.1 mm.

If a shock appears inside the assembly, it can be eliminated by adjusting the gap with your own hands. The steering shaft is centered using two bearings, one located in the column bracket and the other inside the power amplifier housing. The bracket connects both to the pedal attachment point, i.e. to its front part, and to the body. Structurally, the bracket together with the pipe forms a hinged connection from a pair of plates. This unit provides a change in rudder position where the range of motion is limited by slots in specified plates.

The specific position of the tube is fixed by a lever, which is connected to a special bushing that performs the adjustment. It screws onto a coupling bolt located directly in the grooves of the plates. When the lever is turned, the bushing rotates synchronously. At this time, the fixation of the plate weakens, and the steering wheel begins to succumb to changing its position. Springs in the center of the bracket and plate pull the tube up, loosening the connection.

Again, the steering of the Lada Kalina has two rods and articulated arms. The design of the stop includes two tips: external and internal. The process of adjusting the length of the rod is carried out by turning the threaded bushing present here. After completing the adjustment manipulations, the position of the tips should be secured with bolts of a special design. The end of the outer rod is connected to the pendulum bracket through a ball joint.

Power steering, powered by an electric drive, changes the degree of gain depending on the speed of movement. When the car is stationary, the power steering delivers maximum torque and the steering wheel turns very easily. As the speed increases, the force on the steering wheel of the Lada Kalina increases, which is facilitated by a decrease in the torque generated by this unit. The mechanism is based on an electric motor, which transmits rotation through a gearbox “hidden” under the column casing. The amplifier is controlled by an electronic unit, which receives impulses from speed sensors, recognizes the force when rotating the steering column shaft, and also reads the number of revolutions of the engine shaft. There is a special indicator on the dashboard that allows you to monitor the operation of the amplifier.

Causes of knocking noises and dismantling the rack

The most common cause of detonation is excessive wear on the ball joint of the tip. This malfunction requires prompt replacement of the specified element, since further movements can become dangerous, and everything can be done with your own hands using a special repair kit.

The presence of malfunctions in the mechanism considered here, in addition to shocks, may also respond to steering kickback, which is noticeable to the driver.

It is also possible to bite the LADA Kalina steering wheel in extreme positions. Here, adjusting and repairing the steering rack is an absolute necessity. If after these measurements the expected result is not observed, the only solution is to replace the steering rack assembly. A fairly common cause of detonation is a banal loosening of the bolts on the crankcase of the unit.

The design solutions present in the caterpillar do not allow adjusting and tightening the spring without disassembling the mechanism. But it is possible to replace it yourself using a repair kit.

To remove the binary file, you will need to follow the following sequence of steps.

1. We lift the front part of the LADA Kalina car using the available specialized tools.
2. We drive the LADA Kalina in the cabin and unscrew the bolt that holds the steering column in the adjusted position.
3. Remove both front wheels.
4. Unscrew the nuts of the swing arms and pull out the ends.
5. Under the hood you will need to remove the battery paired with the platform.
6. We take out the heat reflector.
7. We unscrew the fasteners that secure the electric power steering rack to the body. Now we calmly remove the knot from the outside.

To disassemble the mechanism, you will need to purchase the following set of tools.

1. A special key that allows you to adjust the VAZ guide structures.
2. A dial indicator with which the gap size will be adjusted.
3. Pliers, screwdrivers and wrench sets.
4. Puller for hammer, hammer and tie rod end.
5. Using a chisel, feeler gauge and brush.

How to adjust the spring and tune the amplifier?

Hedge

The spring requires adjustment due to its natural tendency to stretch over time. Tightening must be done after disconnecting the steering shaft. The promotion does not imply the need to remove the entire mechanism from the car.

Repairing the rack consists of correctly adjusting the gap between the toothed shaft and the rack itself.

1. To do this, the stand must be placed in a central position and secured from spontaneous displacement.
2. Remove the rubber plug.
3. We insert the indicator probe inside the open hole and force it to touch the stop (closed).
4. We make turns of the gear shaft, with the help of which we push out the stop. We measure the length of its movement with an indicator; it should be within 0.05 mm.

If the measured value exceeds the set limit, it is corrected by turning the adjusting nut. After completing the procedure, check whether the rack with the electric booster rotates easily in the crankcase by turning the steering wheel all the way in both directions.

Please note that the adjusting nut must be turned with a special wrench. Do not try to tighten this nut too much as this may make it difficult to turn the steering wheel, especially in extreme positions. It is recommended to make adjustments in stages. First, turn the key 20-25 degrees and check the assembly for no shocks when running the rack. If the shot does not disappear, add a rotation angle of about 10-15 degrees and check again. It happens that tightening does not lead to the expected result. This suggests a repair and may require replacing just the steering rack.

Electric amplifier

It is better to regulate this unit in Lada Kalina after disassembling the electric power steering rack. However, there is a method that allows you to perform this action without having to remove the specified mechanism.

1. We install the car above the pit to provide access to the front amplifier mount.
2. Tighten the clamping nut. If we do it from below, we rotate in the direction of the arrow for an hour, and if we do it from above, of course, the opposite.
3. For preventive purposes, we check the integrity of the oil seal. Please note that sharp and frequent rotation of the steering wheel leads to premature wear of this sealing element.

Selection of repair kit

Before starting repair and restoration work, you should decide on the choice of repair kit.

• Minimum set. This set includes the necessary list of fastening and sealing elements: washers, bearings, nuts and fluoroplastic bushings.

• The basic set has bearings and shafts in addition to the minimum set, but its cost can be twice as high as the first option.

How to disassemble and repair a rack when jammed?

The repair procedure, for example, replacing a steering rack, begins with disassembling the unit. To perform a number of actions, we purchase a repair kit.

1. To disassemble the guide, unscrew the adjusting nut, then remove the thrust bushing. If at the moment we are experiencing difficulties, we use a hammer, with which we apply light blows to the body of the rack and pinion.
2. We disassemble the side plugs along with the trunk. Pre-cut plastic fasteners.
3. The boot must be replaced with a new one.
4. We also use a hammer to remove the shaft from the rack housing.
5. Inside the freed crankcase we find a plastic sleeve, which we remove using a screwdriver. We also replace this component with a new analogue (present in the repair kit).
6. We clean the internal cavity of the strut housing from old grease. Wash and dry.
7. Add new fat. Lubricate the gear pair with particular care.
8. We inspect all other rack components and replace them if wear is suspected. Dismantling the steering wheel in Lada Kalina occurs as follows.

1. Disconnect the battery.

2. Turn off the airbags. Loosen the clamps and slide them to the side.

3. Disconnect the two-wire horn connector.

4. Move to the steering axis and in the area where there is an arrow, mark the position (until removal).

5. Loosen the steering wheel nut, but do not unscrew it completely.

6. Take the steering wheel and swing it to the sides to bring it closer to the indicated nut.

7. Now align the wheels and set the steering wheel to a strictly straight position.

8. Remove the pin and insert it into the switch block located directly under the steering wheel. At this stage, the steering wheel rim should be firmly secured.

9. After removing the cables, proceed to removing the steering wheel itself.

10. We check the integrity of all elements.

11. Assembly is carried out using the reverse algorithm.

Diagnosis, repair and reassembly techniques

A knocking noise has appeared and it is impossible to eliminate it without preliminary diagnosis. Before determining the cause of the knocking, you should disassemble the rack and subsequently diagnose all its internal elements for the presence of wear and damage.

The disassembly procedure is carried out following this sequence of actions.

1. We place the rail in a vice, taking care to install gaskets made of non-rigid material.
2. Unscrew the nut that secures the mechanism housing.
3. We remove the crankcase pipe and remove the clamps that secure the pipe bushings, after which we dismantle the bushings themselves.
4. We unscrew the nut, which allows for adjustment. The previously mentioned special key, endowed with special edges that allow effective manipulation, is suitable here.
5. We proceed to removing the rack stop spring, then the sealing ring and then the rack stop.
6. Now we can remove the crankcase cover.
7. After removing the bearing cage and ring, remove the rack from the pipe.
8. We dismantle the second important component of the pair - the steering gear shaft.

After completing the disassembly process, we begin diagnosing the bearings and sealing rings of the LADA Granta. After thorough cleaning, we evaluate the degree of wear on the gear sectors, as well as the rack surface and shaft. It is in this mechanism unit that the main cause of knocking may be hidden. If the condition of the parts suggests the need for replacement, then we carry it out. Or maybe you will have to do without replacement, in which case you need to know how to tighten the steering rack.

During assembly of the unit, we lubricate the entire list of critical connections with a suitable compound. We do not skimp on lubrication, since its shortage can further provoke premature wear of the critical components of the LADA Granta rack and pinion unit. This, in turn, will inevitably cause a violation of the regulatory gap, and, as a result, a knock. This point may explain the annoying situation when a newly installed steering rack bothers you with an irritating knock.
