Front suspension VAZ-2107: replacement, repair, tuning, scheme and price

Just have to say that the front suspension VAZ-2107 two-link type, as well as on most rear-wheel drive vehicles. From time to time, it is necessary to check the technical condition of all suspension components, as this affects the normal handling of the car, as well as the comfort of the driver and passengers. Unfortunately, the quality of many components leaves much to be desired, so any element can unexpectedly fail. All the work to check and replace the suspension elements can easily be done independently. However, for diagnosis, for example, it is best if there is a viewing hole in the garage or overpass.

Suspension status diagnostics

And now about how to make a technical inspection of the car, more precisely its suspension, for the detection of malfunctions. First of all, look carefully at the tires. Their wear should be uniform. If the rubber began to wear out on one side more, and on the other - less, then the collapse-convergence of the wheels is clearly broken. In addition, the uneven wear of tires indicates that there is a breakdown in the steering rods. Then you do not need the repair of the front suspension VAZ-2107, and the replacement of the steering.

Then it is necessary to check the clearance in each of the front wheel hub bearings . Do it with a car on a flat surface. It is necessary to take up the wheel, or rather the upper part of it, then sharply pull it toward you. If the play in the bearings is very large, then you will hear characteristic knocking. Please note that in the front hub of the VAZ-2107 there are tapered bearings. They must have a very small backlash. If the bearing adjustment did not help, you will need to replace it.

Check of shock-absorbers

If the front shock absorbers are out of order, they must be replaced. In the presence of oil stains or deformations on the body, you need to install new ones. Note that a broken shock absorber can not extinguish all vibrations of the body of the car while driving. In this case, the front suspension VAZ-2107 will not work properly. Before starting repairs, you need to carefully check the shock absorbers to fully verify their malfunction. To check how well the front shock absorbers work, carefully, trying not to damage the wing, press on the front of the car.

If the shock absorbers are completely serviceable, the body will immediately return to its original state. If the body continues to jump on the springs, it can be concluded that there is a malfunction of the shock absorbers. It does not matter if one or both of the shock absorbers are broken, they need to be replaced only in pairs. It is worth noting that it is necessary to install new ones in the event that there is a leakage of oil from the shock absorber cartridge. In this case, only repairing the front suspension VAZ-2107 will help.

Removal of shock absorbers

First open the hood, turn away the nut, with which the rod is attached to the body of the car. After unscrewing the nut, remove the washer and rubber gasket. Note that the shock absorber rod must be held with the key on 6. But you can use a special device. After that, turn away the two nuts with which the levers are fastened. The shock absorber is pulled down. Full replacement of the front suspension VAZ-2107 is not required.

Note that on a flat surface it can not be removed, even if the stem is completely recessed. It is necessary to slightly raise the entire side of the car on which repairs are carried out. But it is most convenient, of course, to do all the work on the lift or observation pit. After removing the shock absorber, it is necessary to unscrew the nut, which is fastened to the bracket. This bracket is installed on the new shock absorber.

Installing a new shock absorber

Next, proceed to install a new suspension element. In fact, all work is done in the reverse order. First, a lower cushion made of rubber is put on the rod. Then the shock absorber body is placed in its place through a special hole in the lower arm. The rod must be fully extended and held in the bore of the body. That's so easy to repair the front suspension VAZ-2107. The price of one shock absorber is 900 rubles on average.

After that, you need to install a rubber cushion and a washer. You make a nut. At the bottom, tighten the bracket nuts to the lower arm. Then tighten the nut on the stem until it stops. The installation of the new shock absorber is finished, similarly the repair is done on the other side of the car.

How do I replace the upper arm?

It is necessary to change the upper arm of the front suspension VAZ-2107 only in one case: if it has mechanical damages. It should also be removed if the silentblocks are replaced. To carry out the work you will need to 13 and 22, as well as a puller to work with silentblocks. First, remove the wheel, and then unscrew the bolt that secures the car bumper bracket. The upper ball joint must be disconnected from the lever.

All three nuts with which the support housing has been fixed to the lever must be unscrewed with a key by 13. Lift the upper lever, and then turn all nuts on the bolt with the key. With their help, the lever is attached directly to the body of the car. The second, with exactly the same key, is to hold the bolt on the other side, so that it does not rotate.

With a convenient knockout, take out the bolt and remove the lever, from which the front suspension VAZ-2107 consists. To remove the silent blocks, it is necessary to clamp the entire lever in the vice and install the puller. Slowly turn the bolt, thereby pressing out the rubber mount. A second silicone block is likewise dismantled. After this, you can repair the suspension lever.

Installing the lever

With the help of a puller, silent blocks are installed in their places. Note that when installing the upper lever, which is done in the reverse order, it is best to use a new self-locking nut. Also, do not tighten the nut when the wheel is hung. First, it is necessary to replace the bolt that secures the bumper, then load the suspension.

If you need tuning the front suspension VAZ-2107, then it is best to put reinforced levers. For example, from the "Niva". Then install under the lower lever spacer and lower the car on the jack. Next, you need to put in place the ball joint and only then tighten the nut. In the event that you removed the ball joint completely, pressing the finger out of the hub, you also need to replace the nut on it.

Preparing to remove the lower lever

As in the case of the upper arm, the lower one changes when there are damages. Completely remove during the replacement of rubber mounts it does not need. Please note that the transverse link has been attached to it. This is how the front suspension scheme of the VAZ-2107 looks. To make repairs, you need to have heads on 22 and 19, and a puller for springs is also useful. First, remove the wheel and remove the spring together with the shock absorber. The lower ball is detached from the wheel hub and completely removed. After this, using a key on 22, it is necessary to unscrew both nuts that secure the lever to the body of the car.

Removing the lever

Using a key on 19, unscrew the nuts securing the transverse link to the suspension arm. Only then, with the aid of a mounting blade, the shaft must be moved and the lever completely removed. Note that under the axle on which the suspension arm is mounted, there are special washers. With their help, the camber is regulated. Installation of the new lower lever is done in the reverse order. Always install new nuts. With a puller in the new lever, press the silentblocks. That's all, the front suspension VAZ-2107 has been restored, now it will serve for a long time.
