Front springs VAZ 2107 - problems, replacement procedure

The shock-absorbing system of a car is important for comfortable movement. It ensures a smooth ride and successfully absorbs uneven road surfaces. The quality of the suspension largely depends on the condition of the springs. The slightest wear of elements can cause a lot of trouble for the owner. Therefore, it is recommended to carry out timely diagnostics and replacement of old parts.

VAZ passenger cars are equipped with an independent double-wishbone suspension at the front, where springs play a key role. The famous “seven” also requires periodic maintenance of its moving parts. We will discuss further technical diagnostics and repair of the front suspension for the VAZ-2107 model.

Problems with front springs

The springs on the VAZ front suspension are located in the front part of the car on the sides of the engine compartment. Their main task is to “absorb” road imperfections. With prolonged use, parts inevitably wear out and require immediate intervention by a mechanic. Atypical behavior of the car indicates an imminent breakdown. If the car body sags significantly compared to the initial condition of the car, this is a sure sign of wear and tear. Trouble does not come alone, so as a result of body roll, accompanying troubles emerge:

• Drastic reduction in ground clearance

• Increased tire wear

• Rapid failure of other suspension elements
• The muffler and driveshaft periodically cling to the road surface
• The body sways intensely when moving

How to lower the classics correctly?

Welcome! Classic - this name came from the people and it stuck to old cars, many manufacturers have their own line of classic cars (That’s what people call them, in real life, each car has its own real name, which was given to it by the manufacturer), if we talk specifically about Russia, then these cars are the well-known VAZ 2101-VAZ 2107, in common parlance simply “Zhiguli”, of all the cars that are produced at AvtoVAZ, the so-called “Zhiguli” are the hardest to underestimate, and it is especially very difficult to put such cars on the doorsteps, in this In this article we will give you advice on how to properly lower such cars and tell you how to lower the car’s suspension to make it exactly the same as on stock (Comfortable).

Note! To lower such cars, you will need a lot of tools, various kinds of keys, a grinder is required, but you just need to work with it carefully and wear a protective suit, there have already been many cases when a disc flew out of an grinder and simply maimed people, so you can’t joke with this and you need to be extremely careful, and also if the car is planned to be lowered very low, then you will have to touch upon the bodywork, and all this depends on how low the car will lie and how big the wheels will be, you will learn about all this as you read the article!

Summary:

Causes of failure of front suspension springs

The warranty period for standard suspension elements is 5 years. However, actual operating conditions are very different from ideal factory tests. The reason for this is the deplorable state of domestic roads and frequent transitions to different road surfaces.

Therefore, professional drivers advise changing components at least once every 3 years or after 30,000 km of travel.

Front suspension failure occurs for several main reasons:

• Late diagnosis and replacement of consumables
• Defective part
• Driving on poor quality roads

When identifying the first “symptoms” of the disease, it is better to eliminate the problem immediately. Constantly postponing repairs can lead to breakdown of other elements of the car, which will cost the car owner a significant amount of money.

Reviews from car enthusiasts about lowering the Priora suspension

Suspension 2110, supports VAZ 2110, front shock absorbers Plaza Sport shortened -50 gas oil, rear Bilstein b8 gazmas, springs all around Eibach -45 pro kit. To be honest, Eibachs lower the front well, but the rear is almost like stock. I put standard and Eibach springs next to each other, the difference is a centimeter and a half. I didn’t like the fact that the rear didn’t sit down at all and I put the phobos back: they really lowered them - 50, although they were on the 12 and sagged a little. Therefore, I would like the front to be a little lower.

Understated. The racks around the SAAZ are ten-size, with shortened rods. In front there are TechnoRessor -90 springs, SS20 queen support springs (with a lowering of 1 cm), at the rear I cut off the original springs by 3 turns. The struts were pumped up for stiffness, because... the rod stroke is short. Bottom line, the car is a bouncer, it’s very rough, I feel every bump, a small wave - me and the sub in the trunk are bouncing.

On the original struts, put -30 in the rear, -70 in the front, it will lie flat. At first I set everything to -30, the rear was as it should be, the front was generally as it was, then I changed the front ones to -50 and still 2 cm higher than the rear.

Lowering a car suspension is not an amateur activity. However, if you decide to carry out this procedure with your Priora, you need to familiarize yourself with the possible options, choosing the most suitable one. It is advisable to entrust changes to the suspension to an experienced mechanic or use special kits for lowering the landing, which you can easily install yourself.

Signs of spring replacement

There are 3 main signs that indicate problems with the front springs. The presence of any of them or a combination of several indicate one thing - not everything is in order with the car.

Rolling the car to one side

To check the car for the presence of this defect, it is enough to place the vehicle on a flat surface without additional cargo inside. The unnatural skew of the car instantly catches your eye. If the body “leans” heavily on the left or right side, the front springs on the VAZ 2107 need to be replaced. A similar situation concerns an excessive slope on the front or rear axle.

But you definitely shouldn’t blame them alone, and here’s why. The design features of the suspension of VAZ cars from the “kopek” to the “seven” include a landing part in the upper part of the spring (popularly it is nicknamed “glass”). It acts as a top stop. During long-term operation of the vehicle, the glass tends to “fall through”. Externally, the body tilts to one side. The cause of the problem can only be diagnosed by removing the rubber cushion and glass. Typically, the failure of the glass occurs on the front springs, and especially often on the left wheel.

Extraneous noise in the suspension

A breakdown can be signaled by extraneous sounds, the source of which is located in the suspension area. This may include an obvious rattling or clanging sound, or a subtle knocking or grinding noise. Noises occur when the car drives on uneven sections of the road. For example, when hitting a bump or a wheel falling into a hole.

If atypical sounds are detected, a complete diagnosis of the vehicle's suspension and steering should be carried out. The source of the noise may be a ball joint, tie rods, or worn rubber gaskets. If everything is fine with them, the reason lies in the malfunction of the springs.

Extraneous sounds often indicate a split in a certain location. But sometimes the part breaks exactly in two. Then the car body looks skewed to the “sore spot”.

Metal fatigue

Auto mechanics often say that metal is “tired.” What does it mean? Metal fatigue means the loss of its initial properties due to prolonged use. Over time, the element copes worse with its assigned responsibilities.

Several extreme turns on both sides of the part fall into the risk zone, since they bear the main load. At the moment of compression, the rings are pressed tightly and hit each other. After some time, mining areas appear at the contact points of the rings. There is a transformation of the round rod, which gradually takes on a flattened shape.

A spring with a defect does not fully respond to road unevenness, and the suspension gently “sags.” If such a malfunction is detected, it is recommended to replace the part with a new one.

Preliminary inspection

You should start with a visual inspection of the car, preferably in an inspection hole, and compiling a list of parts that need to be replaced along with the springs.

1. Inspect the internal arches and spring seats for cracks in the supporting metal. Welding work may be required.

2. If there are oil stains on the shock absorbers , then they will also have to be changed.

3. Along with the rear springs, it is worth replacing the shock absorber bushings, and at the same time the bushings for the rear links.

4. Inspect the rear brake hose for cracks. A cracked hose should be replaced, followed by bleeding the brake system.

Replace the cracked brake hose with a new one

The list of spare parts for replacing rear springs usually looks like this:

a) rear springs with rubber spacers and metal linings of standard size;

b) bushings for shock absorbers;

We replace shock absorber bushings on a VAZ-2107

c) new torque rods or rubber bushings on them.

When the bushings wear out, it is easier to replace the tie rods as an assembly

What to look for when choosing

When choosing a new consumable, you should pay attention to key characteristics. Knowing the basic parameters will allow you to find the optimal part that suits your specific needs.

Length

The ride height depends on the length. Typically, the manufacturer mentions the recommended clearance value in the technical documentation of the model. In rare cases, the spring lengths of the rear and front axles may differ. But it is advisable not to deviate from the technical parameters from the manufacturer. These parameters are determined by precise technical calculations.

You can deviate from the recommendations in two cases:

• “pumping” the car for the sake of visual customization
• modernization of the chassis for transporting heavy loads

Rigidity

The degree of rigidity determines the behavior of the car on the road and distributes the load across the remaining suspension elements. Soft springs are suitable for comfortable, smooth rides, while hard springs cope well with high loads. Therefore, the choice of rigidity largely depends on the purpose of using the machine.

Among owners of VAZ cars (including the Seven), there is a common problem with purchasing new consumables for their “swallow”. In a single set from one manufacturer, sometimes there are elements with different degrees of rigidity. Unfortunately, it is impossible to know about this in advance, and the body defect appears during use.

To resolve the issue, car owners resort to one of two methods. The first option involves purchasing another pair, usually foreign-made. The second method involves installing spacers.

A spacer is a rubber lining that is placed under the seating area of ​​the “glass”. This method will significantly save the budget of the owner of the Lada.

The degree of spring stiffness depends on several indicators:

1. The thickness of the rod section. A simple law applies here: the thicker the rod, the higher the level of rigidity. However, there are models with different ring diameters, and therefore the rule applies only to classic straight models.
2. Total diameter of turns. Increasing the width of the rings leads to increased softness.
3. Number of turns. The higher the number of revolutions of the rod, the lower the rigidity of the part.

Turning parameters

The main characteristics include two indicators: the number of turns and the thickness of the section. They determine the final degree of rigidity of the part.

It is not uncommon to find original springs with different ring diameters. Externally, they have an oval shape: wide in the middle with a gradual decrease towards the edges. The different diameters of the rings are also made of metal of different thicknesses. For massive turns, a thick rod is used, and the small rings on the sides are made of thin material. This design feature gives it versatility: it dampens small vibrations and large shocks equally well.

But the main “disease” of these models is hidden in the extreme turns. Due to the small thickness of the metal, the side parts of the part are very fragile, and therefore often break on uneven roads. This is the price of comfort: for a soft ride you have to pay for frequent repairs.

An alternative to factory springs is products from third-party manufacturers. A non-original product is made from a rod with a constant cross-section. This negatively affects ride comfort due to high rigidity. But non-original consumables are distinguished by their reliability and durability.

Types

The springs of the shock-absorbing system are conventionally divided into 5 categories, which can be presented in table form:

Finding the optimal solution depends on the intended use of the vehicle and the manufacturer's recommendations.

The standard kit for the VAZ 2107 is original parts from a “penny”. But to improve aerodynamic performance, car owners resort to tricks. Often, instead of standard elements, spare parts from the “four” are chosen, which have a positive effect on handling. True, to install them in the “seven” you need to remove the outermost turn.

Helpful information

A short rod unscrewed from the stocking will facilitate dismantling and installation. For ease of assembly, a new rubber spacer and a metal lining are fixed to the spring with electrical tape or tape. Reinforced springs with VAZ 02 - 04 will increase the load capacity, but the car will become rougher to drive. It is easier to replace the torque rods with new ones without wasting time pressing the bushings in a vice. When experimenting with the height of the springs, you should remember the length of the shock absorber stroke. They may have to be lengthened or different ones used. During disassembly, the brake hose receives extra stress, which can lead to damage.

Follow safety precautions and replacing rear springs will not be a hassle.

AvtoVAZ began production of the VAZ 2101 in 1972. More than three decades have passed since then, but the concept of the “Classics” was discontinued only recently, less than a year ago. Over the course of 300 years, the car has acquired a huge number of supporters, and just as many enemies who hate the domestic auto industry. Let's not take either side. It’s better to talk about how we can improve this line, and more specifically, the VAZ 2107. I must say, this car lends itself well to tuning, although many believe that this task is a useless and thankless task. But in fact, tuning a VAZ is quite simple, relatively cheap and quite interesting. Thus, even minimal modifications make the car much better than it is. Not to say that “it can’t get any worse,” but the fact remains. So, external tuning, which is mainly used for domestic cars, is always capable of changing a VAZ for the better. But, as a rule, things rarely go further than that. But in order to make your car unique, you need to approach this activity with a creative component, so to speak, in a versatile way. After all, the aerodynamic body kit of the VAZ 2107, no matter how effective it is, is not capable of making it drive at a speed of 200 km/; this requires completely different modifications. We will not go into details of increasing power, we will turn towards improving maneuverability.

Main types and ratings of suspension springs

How to choose the best springs for the VAZ 2107 presented on the domestic market? It is impossible to give a definite answer to the question, since each driver eventually finds “his” company, whose products he is ready to trust. A list of 14 well-known companies that have long proven themselves to be the best will help you understand the huge number of brands.

LESJOFORS

The real flagship of the industry comes from Europe. The company has been producing spare parts for car suspensions for many years. The company has a developed network of branches with representation in four European countries.

Lesjofos springs are cast from special steel with a high carbon content. A special protective coating is applied to the surface of the part and then painted. The products are distinguished by their long service life, confirmed by numerous tests. There are over 3 thousand items on the market under a well-known brand. The main disadvantage of the product is the “biting” price tag.

KILEN

At the end of the last century, the company came under the wing of “lesjofos”, and today it is a “daughter” of the giant. Accordingly, the sub-brand’s products have twice the service life compared to the original parts from the Volga plant. Car owners praise the product for its high quality combined with an adequate price.

LEMFORDER

The company is a well-known supplier of original products for many premium cars. Therefore, the price of the product is not the lowest. But in return, the buyer receives unsurpassed quality, supported by countless positive reviews.

CS GERMANY

German company producing components. The products are in the middle price category. Drivers respect the brand for the optimal ratio of cost and quality of the goods offered.

KONI

The company's products are distinguished by a large margin of safety and are widely represented on the market. The price of components is in the “above average” category. The main feature of the springs is the ability to dynamically adjust the stiffness level.

BOGE

The manufacturer produces various parts for car suspension. The manufactured products belong to the “premium” category. The cost of boge products fully corresponds to the class of the company. Manufacturing defects occur rarely; reviews from car owners are mostly positive.

EIBACH

is one of the key players in the automotive market. Its products practically do not lose their initial properties over time and are popularly considered “immortal”. The only thing that spoils the overall impression is the cost of parts from the eminent flagship of the industry, which is many times superior to its competitors.

SS20

The key feature of the manufacturer is a painstaking approach to manufacturing technology. The factory carefully selects pairs with equal hardness. Therefore, when purchasing, you can be sure that the kit is guaranteed to have similar parameters. Production technologies are based on cold and hot winding methods.

K&F

belongs to the leading manufacturers of spare parts for cars and trucks. In addition to supplying new parts, the company actively operates in the secondary market. The rich product range includes over a thousand items. Springs from a famous brand are famous for their quality, but they cost a lot of money.

TEVEMA

Polish manufacturer of shock-absorbing springs operating in the European and Asian regions. The insane demand for the company's products is dictated by the low cost of parts, which are several times cheaper than original components.

SIRIUS

The company produces products in the budget segment. A wide selection of components received positive feedback from car owners. It is especially worth noting the possibility of producing parts according to an individual sketch.

FOBOS

The company does not have enough stars in the sky, but the price tag for the products is appropriate. A small range of products with mediocre quality. Car owners note that the first defects “pop up” after just a year of active use.

ASOMI

The company is famous for its own production technologies, which are kept in the strictest confidence. "Asomi" offers high-quality products at reasonable prices.

TECHNORESSOR

An economical option for those who are broke. The company produces spare parts for cars and trucks. Springs gradually lose their initial properties. An excellent solution for economical drivers.

Work order

1. If there is no hole or repair overpass, select a flat place with a margin around the machine.

2. The front wheels are tightly fixed on both sides using improvised means (shoes).

3. Lightly loosen the rear wheel bolts on the first side.

4. One side of the car is lifted with a jack and a safety trestle is installed.

5. The wheel is removed.

6. Place a hydraulic jack under the edge of the rear axle and lift it slightly to relax the shock absorber.

7. Unscrew with two 19mm wrenches and carefully tap the bottom bolt of the shock absorber.

8. The jack is completely released so that the bridge hangs on the reaction rods (rods).

9. Using a pry bar or a screwdriver, the spring is removed from its regular place on the stocking and removed (towards you, slightly to the side).

Using a pry bar, carefully remove the rear spring of the VAZ-2107

10. Use a wire brush to clean the landing areas for new parts.

11. Installation of a new spring, scrolling until it fits into the standard groove.

Spring Upgrade

The process of upgrading springs involves changing the length of the part on your own. To do this, the element is shortened or replaced with a longer sample.

Shortened springs

Drivers resort to reducing the size of a part in order to improve the characteristics of their iron comrade. Trimming the springs gives the car some advantages:

• Lowering the body position
• Better steering response
• Reduced roll when entering a turn

Many manufacturers offer a ready-made solution in the form of special versions of short springs. However, it is worth remembering that after tuning the ground clearance will decrease significantly. Such a “seven” will not be able to drive on uneven roads.

You can lower the “seven” yourself. To do this, you need to cut 2 turns from each spring using a grinder.

It is not recommended to cut off more rings, because the body will touch the ground.

The video shows working with a VAZ 2106, but the technological process for the “Seven” is completely identical.

Some bad decisions

When a person decides to tune his VAZ 2107, he must be prepared for the fact that he will have to change the characteristics of other parts of the car. In this case, it is imperative to lower the suspension, as it will help maintain stability on the road.

Inexperienced owners use a rather primitive method of how to do this. They simply shorten the spring by about 2-3 turns

. Yes, indeed, the clearance in this case becomes smaller, but such a procedure carries with it a number of negative aspects.

When cutting the springs, there is a high probability that the car will become not just stiff, but super-stiff. In addition, its handling will deteriorate significantly. At the same time, we should not forget about the wear of the chassis, which also increases significantly.

Thus, if a car enthusiast decides to do such tuning on his own, then he has to look for alternative methods that do not have such a detrimental effect on the car.

Spacers for springs

Even the most innovative springs gradually exhaust their service life. And the owner is faced with a choice: replace the part with a new one or extend the life of the element with the help of a spacer.

The spacer for the VAZ 2107 has several varieties:

• Interturn (attached between the rings)
• Butt (between the spring and the cup)
• Suspension spacer

An interturn spacer is suitable for spring repair. You can buy it at a VAZ car parts store. Installation is performed in the following sequence:

• Raise the wheel with a jack
• Unclench the required coils of the spring with crowbars
• Soak the spacer with soapy water
• Insert the spacer with a screwdriver and secure it
• Remove the jack from under the wheel
• Repeat all steps on the other wheel

The best way

In order to achieve your goal, you definitely need to think about purchasing only high-quality spare parts

, which are created specifically for tuning. They were listed in the tools and materials section. This is the only way to reduce the harmful effects on all parts of your steel horse.

If we talk about other classic models of the domestic automobile industry, then here all the work is carried out in a similar way. Experts also advise using exclusively special parts and not cutting springs.

As for the actual process of installing new springs

, then it is standard, that is, no additional innovations are required. Everything is done in accordance with the rules of standard assembly of the vehicle chassis. Moreover, each individual part is always equipped with a manual, which you need to study in order to do everything really well.

Do not forget about the negative aspects that this procedure brings. The most important thing is that the car becomes much stiffer. This is felt throughout the body. There are also undeniable advantages.

We also recommend reading our article: “Do-it-yourself modifications to the VAZ 2107.”

Do not forget that after carrying out the work, the brake force regulator on the rear axle must be adjusted. If this is not done, the car will consider that it is overloaded. The rear wheels will skid during heavy braking.

Thus, there are two main ways to lower a VAZ 2107. As you can see, simply trimming the springs is ineffective

, as it leads to a decrease in the performance of the machine. It is better to use special spare parts for tuning, since only they can truly replace original components with high quality.
