How to change springs on a VAZ 2106

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 effectively suppress the shock that occurs when driving on uneven surfaces. The springs also prevent the vehicle from tipping over when entering a very tight curve. Finally, the springs keep the body at a constant height while riding on the road.

Externally, the spring is a rod made of structural steel and twisted in a spiral. The suspension of the earliest cars was equipped with springs. But now almost all cars are in spring, because they take up less space in the body and are easier to maintain. In the VAZ-IE 2107, in addition to springs, there are also shock absorbers, the main task of which is to suppress vibrations that arise as a result of spring work.

About the stiffness of car springs

Speaking about the spring definition, it is impossible not to mention such important properties as rigidity. Drivers usually separate the suspension into "hard" and "soft" ones. In the VAZ 2107 model, both types of suspension were used. And their application results with the purpose of the car.

If the owner of the “seven” loves speed and prefers an aggressive driving style, wear a rigid suspension, which makes the car as stable as possible at steep angles. And if the driver is not used to rushing, he should put on a soft suspension, which provides maximum driving comfort on uneven roads. The stiffness of the “seven” springs depends on the following parameters:

• Diameter of the spring rod. As the rod diameter increases, the spring stiffness increases;
• The diameter of the spring itself. Spring diameter means the diameter of the cylinder formed by the coiled spring rod. The larger the diameter, the softer the spring will be;
• Number of turnover. The more rotations on the spring, the softer it is;
• Form. Springs can be cylindrical, barrel or cone. Coil springs are considered the most comfortable, the barrel is too soft, and conical springs occupy an indirect position between coil and barrel springs.

what kind of lubricant is on the rubber spacers?

Isn't this dangerous for rubber products?

I don’t know, I lubricated it “just in case” so it wouldn’t creak

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.

About the choice of springs

As mentioned above, the choice of springs should be based on the purpose of the vehicle. Someone who goes fast expects hard springs, and someone who likes comfort expects soft ones. There is another situation when it does not turn on without replacement: the springs may “get tired”. It's simple: over the course of many years, the flexibility of each spring decreases. If this happens to the back of the Seven, the rear of the car will begin to bend, and the wheels falling into a particularly deep hole will begin to hurt the fenders with a characteristic attitude. Then the driver simply needs to be installed with new hardness sources. Which to choose?

VAZ springs

When the springs are worn out, the best solution is to install a set of standard rear springs in a VAZ 2107. If for some reason you cannot buy “original” springs, there is another option: spring ones from a VAZ-A 2104. They are slightly more stiffer than the original springs, and the driver prefers an aggressive driving style, will likely notice an improvement in the car's handling. Additionally, springs from the "four" are used by those who decide to convert their "seven" to gas fuel. Gas cylinders are heavy, so the rear springs need to be stiffer and have more clearance. Finally, there is a third option: Springs from a VAZ 2101. Today you cannot always buy new springs from Kopek, because Kopek has long been withdrawn from production. But if you can still get these sources, the "seven" suspension after they are installed softer.

About springs from foreign cars

It is not recommended to assemble rear springs from a foreign car in the VAZ 2107 model. The fact is that the parameters of these springs are not even similar to standard vases. Springs for foreign cars are designed for a different car weight, different body type, different shock absorbers, etc.

If the driver decides to build them, he will have to make major changes to the 7's suspension and will almost certainly have to replace the rear shocks, which will incur additional costs. However, even such measures do not guarantee normal suspension. Consequently, drivers who are engaged in their “seven-seater” tuning, they prefer not to combine with springs from foreign cars, cope perfectly with the VAZ-uprings mentioned above.

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.

1. Remove the wheel and place a block under the lower arm so that you can unscrew the shock absorber.
2. Having opened the hood, unscrew the shock absorber rod from above, and 2 bracket bolts from below, and pull out the part.
3. Place the ties on the spring and secure without tightening the studs.
4. 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.
5. 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 modernization of VAZ 2107 springs

In an attempt to eliminate "inherent" suspension defects or solve a specific problem, the driver may resort to upgrading the rear springs by shortening them or using a strut. Let's consider each case in detail.

Spacers for springs

Home roads have never been of good quality. The VAZ 2107 has never been distinguished by its great design. At some point the driver got bored with releasing each hole and decided to increase the clearance of his car using special lines. These are small annular spacers made of wear-resistant materials. Let's change the types of spacers.

• Distance washers installed between the coils. This is the easiest and most popular way to increase the test on a car without major upgrades. Assembly does not require any special skills. The wheels are sequentially raised, suspended and springs slightly pulled out. It is inserted between the coils wet with water soap. These spacers can be found on every aftermarket. The simplest spacers installed between the rear spring coils
• Spring stands. They are installed directly under the back and front springs. The increase in clearance corresponds to the thickness of the washer gasket. Installing spring spacers is more complicated: you first remove the wheels and then the spring. A novice driver will find it difficult to perform such an operation, so it will not be written without the help of a qualified mechanic. Important note: spring distances are only good for new sources. However, if the spring has lost its elasticity and is “sitting”, it makes no sense to put it under it, because the effect of the washer will be zero. A more reasonable solution in this situation is to purchase and install new springs and spacers, which are installed in the thrust sockets for the springs.
• Adjustable spacers. They are the same as spring spacers, but their design allows you to change the gap using special screws. These struts are the best option for those who want to increase the ground clearance of their “Seven”. But these dividers have three disadvantages: they are difficult to install, they are expensive, and they are not available everywhere. Adjustable dividers are the most convenient and expensive.

About spacer materials

The material from which the spacers are made deserves special attention, because this is the most important aspect that determines the reliability and durability of not only the springs, but also the entire suspension. So, spacers can be:

• aluminum;
• polyurethane;
• plastic.

Now a little more about each of these materials:

• Polyurethane gaskets are quite easy to install, but are not durable. Their main problem is that the spring greatly deforms them, and this happens in the shortest possible time. Especially if the driver constantly drives on uneven roads. Over time, deformation of the spacer bushings causes them to rub against the vehicle body, causing serious damage; Polyurethane spacers have never been known for their durability.
• aluminum spacers. They are more reliable than polyurethane spacers and do not allow the liners to rub against the car body. But they also have a downside. Some aluminum spacers may contain steel components that are easily susceptible to corrosion. This is especially true when the driver drives on roads that are frequently sprayed with chemicals; Aluminum spacers are more reliable than polyurethane ones, but also more expensive.
• spacers made of durable plastic. This is the best option. They wear out for a long time, do not deform and are not subject to corrosion. The only drawback of plastic spacers is their high cost. The best dividers for “sevens”, but their price is sometimes very high.

On the advisability of installing spacers

The possibility of attaching struts is a very controversial issue that continues to this day. Walking has many followers and many opponents. If a driver comes to a car service center and asks to install spacers, they are installed. However, as a rule, specialists first dissuade the driver from doing this. Their arguments usually boil down to the following points:

• After installing the struts, the wishbones will be lowered permanently by a few centimeters. This leads to a violation of the geometry of the entire suspension. Therefore, the suspension will work differently. There may be changes in the track, vehicle handling, wheel axle angles, etc. Under normal conditions, all this will not be very noticeable. However, in an emergency situation, improper handling can have very disastrous consequences;
• Attaching struts increases the load on the suspension. Shock absorbers wear out faster, as do silent blocks. This is due to the fact that the steering rod and drive shaft rotation angles change when spacers are installed.

The takeaway from all this is simple: the rider will have to carefully weigh the pros and cons and decide whether he really needs such an upgrade before installing struts.

"Seven" and "Ten"

For appropriate repairs on the “classic” we will take the following tools:

• set of wrenches;
• wheel chocks.

Find out how much it costs to change brake pads and about replacing the rear strut on a Honda Stepwagon.

So, let's figure out how to replace the rear springs of a VAZ 2107. This is what needs to be done, and from the inspection hole.

1. Unscrew and then remove the pressure regulator rod of the brake circuit system from the mount. It is also necessary to remove the brake hose tee.
2. We unscrew the bolt of the lower shock absorber mounting, take it out, and remove the strut from the mounting.
3. Next, having installed anti-roll pads under the front wheels, we lift the rear of the car with a jack so that the axle lowers.
4. We take out the released defective part, as well as the lower and upper linings. We directly replace the spring from the rear suspension of the VAZ 2107, attaching pads to the new spare part.
5. We do the assembly in reverse order.

Conditions for replacement, tool

You can change the rear springs yourself even in the absence of an inspection hole (only a jack is sufficient). You can find out the dimensions of the socket heads and spanners required to unscrew the upper or lower shock absorber mountings in the repair and operating manual for your car model. In some cases, having two jacks will make the process much easier.

Replacing rear suspension springs will be much easier if you use special ties. For example, on a VAZ 2101, 2102, 2106, 2107, you can remove the old spring and install a new one using conventional installation, but the design of the rear suspension of many other cars will not allow such a trick. We will show you how to change rear springs without zip ties, but we recommend using this method only if absolutely necessary. The price of screeds is not so high as to sacrifice your own safety.

DIY Replacement Guide

We will demonstrate the replacement procedure using the example of a VAZ 2101-2107. After reading the instructions, you can easily carry out this procedure on another car, since the basic provisions apply to all types of rear suspension.

1. Loosen the wheel bolts.
2. Raise and secure the rear part of the car on the supports. Be sure to install the wheel chocks diagonally (if the rear right side is raised, the chocks are installed under the front left wheel).
3. Unscrew the lower shock absorber mounting. If for any reason problems arise with the bottom bracket, you can unscrew the top mount. The shock absorber will limit the travel of the beam (on cars with rear-wheel drive and all-wheel drive - the rear axle), so we need to disconnect one of its fasteners from the car body.
4. Using a pry bar, pry the lower end of the spring by the coil to release it from the mounting groove. There is no need for such manipulations if the spring is slightly tightened with ties.

When tightening, be sure to ensure that the coils are tightly secured by the claws of the ties. If the spring jumps out, it can cause serious injury!

How to properly install new springs

On many cars, there are special grooves in the upper and lower cups for fixing the outer turns. During installation, it is important not only to clean the seats from dirt, but also to ensure that the outer turns are positioned correctly.
