Replacing the rear springs of a VAZ 2107: how to remove and install, which ones are better, instructions with photos and videos

The need for such an event as replacing the rear springs of the VAZ 2106 is caused by their wear or destruction. Wear is expressed in the subsidence of the car during operation; destruction occurs with constant overload or driving on country roads. Some car enthusiasts remove springs in order to change worn rubber spacers, which can also cause the car body to settle.

Replacing the VAZ 06 springs can be done on an open, flat area, having good anti-recoil means, since the car will have to be raised and lowered several times. The process itself is simple; almost every VAZ 2106 owner can do it. To do this you will need:

jack and wheel wrench;
wheel chocks or comfortable stones;
a set of spanners or open-end wrenches;
2 spring ties;
low wooden block or cinder block;
powerful flat screwdriver;
hammer;
fabric gloves.

During such repairs, cloth gloves are worn to avoid injuring your hands during the work on the protruding parts of the suspension and car body. Spring ties can be found from one of your car enthusiast friends; many VAZ 2106 drivers have this device in their arsenal. As a last resort, it can be purchased at an automotive supply store. Replacing springs also involves replacing rubber spacers, which serve as a gasket between the upper coil of the product and the glass in the car body.

Purpose of rear springs on VAZ 2107

Rear springs are essential for a comfortable ride. They are the most important part of the suspension and successfully dampen the shaking that occurs when driving on uneven roads. The springs also prevent the car from tipping over when entering a very sharp turn. And finally, when driving on a flat road, the springs keep the car body at a constant height.

The rear spring on the VAZ 2107 is located far behind the wheel

Externally, the spring is a rod made of structural steel and twisted into a spiral. The suspensions of the very first cars were equipped with springs. But now almost all cars have springs, because they take up less space in the body and are easier to maintain. In addition to springs, the VAZ 2107 also has shock absorbers, the main task of which is to dampen vibrations resulting from the operation of the spring.

About the stiffness of car springs

Speaking about the purpose of springs, one cannot help but dwell on such an important characteristic as rigidity. Car enthusiasts usually divide suspensions into “hard” and “soft”. The VAZ 2107 uses both types of suspensions. And their use is determined by the purpose of the machine.

Spring stiffness depends on many different parameters

If the owner of the “Seven” loves speed and prefers an aggressive driving style, he installs a stiffer suspension, which makes the car as stable as possible on sharp turns. And if the driver is not used to rushing, then he should install a soft suspension that provides maximum comfort when driving on uneven roads. The stiffness of the “seven” springs depends on the following parameters:

diameter of the spring rod. As the diameter of the rod increases, the stiffness of the spring also increases;
diameter of the spring itself. Spring diameter refers to the diameter of the cylinder formed by a twisted spring rod. The larger this diameter, the softer the spring will be;
number of turns. The more turns in the spring, the softer it is;
form. Springs can be cylindrical, barrel-shaped or conical. Cylindrical ones are considered the hardest, barrel-shaped ones are the softest, and conical ones occupy an intermediate position between cylindrical and barrel-shaped ones.

Front suspension assembly disassembly sequence

Replacing the front springs of a VAZ 2106 is somewhat more complicated; you will need to completely unscrew or remove the shock absorber or unscrew its lower mounting bracket, which is not very convenient. The operation is complicated by the fact that the stand is located inside the spring and will not allow it to be pulled out. Otherwise, the process is very similar, only the block will need to be placed under the lower suspension arm. It is important to maintain consistency here.

Remove the wheel and place a block under the lower arm so that you can unscrew the shock absorber.
Having opened the hood, unscrew the shock absorber rod from above, and 2 bracket bolts from below, and pull out the part.
Place the ties on the spring and secure without tightening the studs.
Turn the steering wheel all the way out to gain access to the lower ball joint nut. Loosen and unscrew the nut, and lightly hit the bushing with a hammer to knock the ball joint pin out of it. The force of the compressed spring will help push it out.
Now you can raise the jack and remove the spring along with the ties. Further work is performed as described above.

In order not to buy new springs, VAZ 2106 owners often purchase higher rubber spacers, these are commercially available. They are also placed under the rear springs in order to raise the rear of the car for transporting heavy loads. In this case, the matter becomes simpler. After removing the tie part, there is no need to twist it, just change the rubber product, and then assemble the entire assembly.

About the choice of springs

As mentioned above, the choice of springs should be based on the purpose of the vehicle. Those who drive fast install hard springs, and those who love comfort install soft ones. There is another situation in which replacement is indispensable: the springs may get tired. It's simple: over the years, the elasticity of any spring decreases. If this happens with the rear springs of the "seven", then the rear of the car begins to sag greatly, and the wheels, falling into a particularly deep hole, begin to touch the fender liners with a characteristic grinding sound. After this, the driver is simply obliged to install new hard springs. Which ones to choose?

VAZ springs

If the springs wear out, the best option would be to install a set of standard rear springs for the VAZ 2107. If for some reason it was not possible to purchase “original” springs, there is a second option: springs from the VAZ 2104. They are slightly stiffer than the “original” springs, and drivers who prefer aggressive driving style, you will probably notice an improvement in the car's handling. Also, springs from the “four” are installed by those who decided to transfer their “seven” to gas fuel. Gas cylinders are heavy, therefore the rear springs must be stiffer and their free travel must be shorter. Finally, there is a third option: springs from a VAZ 2101. Today, it is not always possible to purchase new springs from a “kopek”, since the “kopek” has long been discontinued. But if you still managed to get such springs, the suspension of the “seven” will become softer after installing them.

About springs from foreign cars

It is not recommended to install rear springs from foreign cars on the VAZ 2107. The fact is that the parameters of these springs do not even come close to the standard VAZ springs. Springs on foreign cars are designed for a different car weight, a different body type, different shock absorbers, etc.

Installing springs from foreign cars on a VAZ 2107 is impractical

If the driver decides to install them, he will have to seriously modify the 7's suspension and will almost certainly have to change the rear shock absorbers, which will lead to additional costs. But even such measures do not guarantee normal operation of the suspension. Therefore, drivers who are tuning their “sevens” prefer not to mess with springs from foreign cars, getting along just fine with the VAZ springs mentioned above.

Instructions for working with rear springs

Before proceeding with the replacement, you should place 2 shoes under the wheel located diagonally from the one being removed. Replacing the rear springs begins with unscrewing and removing the wheel, after which you need to place a block at the end of the rear axle beam and lower the jack. The entire mass of the car will fall on the block and compress the spring. The block should be positioned in such a way that it does not interfere with unscrewing the lower shock absorber mount. Follow the instructions further.

Loosen the shock absorber mounting nut, unscrew it and remove the long bolt. The shock absorber must be unscrewed so that the spring can then be removed.
Place 2 ties on opposite sides on the spring coils and securely fix them by pressing the pins with a wrench.
Raise the car body with a jack until you can pull out the spring along with the ties.
As a rule, the rubber spacer sticks to the metal of the body and remains in the glass, only the iron ring falls out. Therefore, you need to use a long flat screwdriver to pry up the rubber and remove it from the socket.
Loosen the grips of the ties by unscrewing the studs one at a time with a wrench. Replace the ties on the new spring and tighten it to the approximate dimensions of the old one.
Place a new rubber spacer with an iron washer on the upper coil of the spring. Its configuration is such that it must coincide with the shape of the upper turn.

1 — lower longitudinal rod; 2 — rubber bushing; 3 — bracket for fastening the lower longitudinal rod to the body; 4 — spacer sleeve; 5 — upper longitudinal rod; 6 — additional compression progress buffer; 7 - spring; 8 — upper spring cup; 9 — compression stroke buffer; 10 — upper insulating gasket of the spring; 11 — shock absorber; 12 — lower insulating gasket of the spring; 13 - transverse rod.

Place the part in the socket together with the ties and, supporting it with one hand, lower the jack with the other until the grips of the ties relax.
Remove the ties, screw on the shock absorber and perform further assembly in reverse order.

When it's time to replace

There are several signs by which you can determine that it is time to replace the springs. These signs are:

Detection of damage and defects in the product design. This malfunction can be determined by visual inspection, but first you need to put the VAZ 2107 car on an overpass.
Their significant subsidence. If the vehicle's ground clearance decreases significantly, this indicates sagging of the devices in question. Springs quickly sag in such cases when the car is used to transport heavy loads every day. Also, those cars that are used as taxis also require frequent replacement of the devices in question.

If you find a problem with the springs on a VAZ 2107, then you should replace them without delay. This will extend the life of other suspension elements and save money. It is recommended to replace devices in pairs, since replacing only one element will cause the body to skew, which will negatively affect driving. In some cases, spacers help when the springs have sagged but are not deformed. Experts believe that you should not get carried away with spacers, since the physical properties of a car with spacers are many times worse. As a result of such modifications, the suspension does not function correctly, which affects many factors: from control to comfort. Therefore, if necessary, it is better to replace the springs, both rear and front. We will learn how this is done on a VAZ 2107 from this material.

Replacing the front springs of a VAZ 2107

Replacing the front suspension elements on the “seven” is carried out according to the following scheme:

First, you need to install the car on an inspection hole or overpass, and then begin to remove the wheels, having first jacked them up.
The front shock absorber needs to be removed.
The nuts that secure the lower arm to the axle are loosened.
Using a second jack, you need to place it under this lever, thus adding the suspension load. This is done to make it easier to disconnect the stabilizer.
At this moment, you can use special spring ties (if available) to secure the springs in a compressed state. This will make further removal actions much easier.

The front springs of the VAZ 2107 need to be changed in pairs, just like the rear ones.

Changing the rear springs on a VAZ 2107

Replacing the rear springs of a VAZ 2107 is carried out according to the following principle:

Install the jack and remove the wheel.
The pressure regulator rod in the brake system is unscrewed.
The rear pipe tee bracket is unscrewed.
The shock absorber fastener at the bottom is unscrewed.
Jack up the car and thereby release the shock absorber and spring fasteners.
Now you can remove the spring, which also has a rubber spacer. If the spacers are deformed, they should be replaced.
Replace the removed springs with new ones, installing all the removed parts in the reverse order of removal. When installing products, it is important to purchase special ties, as shown in the photo below.

Replacing the rear springs is much easier and faster, so it will take half a day to replace all four products.

What springs to install

It remains to figure out the question of what springs to put on the VAZ 2107? Instead of standard products, you can install reinforced devices. The replacement principle is similar, but the result will be significant. The suspension with reinforced devices will become stiffer, but it is important to know that at the same time you will need to install new shock absorbers (more powerful).

Many car owners are wondering what springs are best to install on a VAZ 2107? The best option for a rear-wheel drive sedan is products marked 2101. They are quickly and easily installed in standard places and do not require modifications. When choosing products, you need to pay attention to their manufacturer. There are many manufacturers, both domestic and imported, but it is important to pay attention to the cost. When choosing, pay attention to the stiffness class of the springs, the number of turns and their thickness. There are two types of hardness:

Frequent malfunctions

Knocks

Knocks in the rear suspension can be of different types and the reasons for their occurrence are also different:

knocking sound when starting. The malfunction occurs when one of the rear axle reaction rods or the brackets that hold them break. To solve the problem, it is necessary to inspect the suspension, identify the damaged rod and replace it;
knocking noises while driving. Broken silent blocks of jet rods can knock. Over time, the metal bushing simply begins to dangle in the rubber, and the bridge “walks,” which leads to the appearance of extraneous sounds. The malfunction is treated by replacing the rubber bushings of the rear axle rods;
knocking noise when the suspension is compressed too hard. This happens when the bump stop is damaged, causing the suspension to “break through.” Therefore, it is necessary to inspect the buffer elements and replace the failed ones.

Breaks through the suspension

Such a concept as “breakdown” occurs when the suspension does not cope with its function. There may be several reasons for this:

rear axle overload. The suspension can often “punch” due to an overloaded rear axle, for example, if the car is heavily loaded. In this case, you need to unload the rear axle;
breakage or settling of the spring. Despite the fact that the springs are made of durable steel, they still sag over time, especially with frequent transportation of goods. The way out of the situation is to install new or stiffer springs;
failure of shock absorbers. If the shock absorbers are unable to dampen vibrations, then full operation of the suspension is impossible. The shock-absorbing elements will need to be replaced.

The car is pulled to the side

Sometimes with the suspension of the VAZ “Seven” there are such nuances when the car pulls to the side. Let's list the reasons why this can happen:

spring breakage or settling. Due to a damaged spring, the car will stand unevenly on the road, which may cause it to move to one side. The spring will need to be replaced;

Damage to the spring may cause the vehicle to pull to one side.
displacement of the rear axle due to wear of the silent blocks of the reaction rods. The appearance of free play in the suspension elements leads to unstable behavior of the car on the road, which indicates the need to replace rubber-metal components.

There can be many more reasons why a car pulls to the side. In addition, a malfunction is possible not only in the suspension, but also in other components, for example, with a flat tire.

Other sounds

Extraneous noises and sounds can come not only from faulty suspension elements, but also from the chassis, which is not always easy to determine with insufficient experience. While driving, a hum from the rear axle gearbox itself may be heard from the rear of the car, which requires adjustment or replacement.

In addition to the gearbox, the axle bearings may hum as a result of wear or a small amount of lubricant. When the springs sag, the wheels may touch the plastic wheel arch liners when cornering, if they are installed. They can also simply loosen the wheel bolts if they are loosely tightened, which will lead to extraneous noise.

Therefore, each specific case needs to be dealt with separately, where and at what moment this or that sound comes from. Only in this case will it be possible to more accurately diagnose the malfunction.
