Replacement of Silentblocks VAZ-2107. Replacement of upper and lower silentblocks VAZ-2107

Replacement of Silentblocks of VAZ-2107 is quite simple. For this you do not need to have any special skills, to get a secondary technical education in the specialty of a mechanic. It's enough just to get a normal tool and necessary for work pullers. However, sometimes you can do without them, only repairs will last a little longer. In this article, we will try to consider how the rubber-metal hinges are replaced on the seven. This same manual can be used for all other models of the classic series.

What are Silentblocks for?

All cars, which are called classic, have rear wheel drive. Consequently, the front suspension is more complicated, compared with the "MacPherson", which is used for front-wheel drive cars. From here it can be concluded that the replacement of the front silencers VAZ-2107 should be made as often as possible in order to avoid problems with control. The appearance of rubber-metal hinges resembles a glass. Inside, it is made of metal, topped with rubber.

The suspension levers are exactly the elements in which the silent blocks are mounted. In total, on the front of the VAZ-2107 there are four levers - two on the left side, on the right there is the same. They are attached to the body by means of rubber-metal hinges. It was possible, of course, to use ball bearings for this purpose, but they would have a much lower resource. And they could not smooth out the blows while driving on a rough road.

Diagnostics of rubber-metal hinges

To check the condition of the silent blocks, it is necessary to use a pit or trestle. Without such facilities, it will be problematic to carry out diagnostics of the suspension and drive of the seven, so the pit must be in each garage. The car is budgetary, therefore, it can be repaired without any problems with one's own hands. But you need to determine whether replacement of the V-2107 silentblocks is necessary, the price of one is about 50 rubles. For a set of 8 silentblocks you will give 400 rubles.

Carefully inspect the suspension on the lever, evaluate the appearance of the rubber mount. If the rubber has obvious damages - it began to become covered with cracks, or there are cuts in general, it is necessary to replace all the elements. When carrying out repairs, try to make the most of the work. Therefore, not only all eight silentblocks are changed, but also, after evaluating the condition of the ball joints, carry out replacement if necessary. It is also worth looking at the condition of the bearing of the hub, if necessary, tighten the nut.

Tools for work

You need a good jack. It is desirable, of course, hydraulic, since it is much more convenient to work with it. But if there is not one, then use the one that is available in your arsenal. Also need support for the car and chocks. With their help, you will not let the machine roll down and fall. The replacement of the upper silent blocks VAZ-2107 is made after removing the lever. But for pressing out the hinge you will need a special puller. Its cost is slightly less than the set of hinges, but it will be useful in the future, the next repair of the suspension. And of course, you need a standard set of tools - car keys, spanners, and end caps.

Replacement of Silentblocks on the upper lever

To replace the hinges on the upper arm of the seven suspension, you need to remove it. It is not difficult to do this, you just need to lift the wheel and unscrew the bolts of its fastening. After that, your eyes will open a charming view of all the suspension elements, including the upper lever. It replaces the V-2107 silicone blocks only after complete dismantling. Note that the lever is attached to the body by means of an axle-bolt, and also to the hub by means of a ball bearing.

The ball does not need to be pressed out of the hole in the hub, just unscrew the three bolts that secure it to the suspension arm. Completely to remove it it is necessary only in case of replacement. After you unscrew the three bolts ball, it is necessary to remove the lever from the body. To do this, unscrew the nut from the shaft and knock out the latter. That's all, the lever is removed, now grip it more tightly in a vice and using a puller to dismantle the old hinges. With the same remover, put new ones in place. And now you can mount the lever in place.

Replacement of Silentblocks on the lower arm

A little easier is to replace the lower silent blocks VAZ-2107, as it is not necessary to remove the lever. Instead, one by one, unscrew the fastening nuts (first ahead, then behind). Install the remover and press it out with a hinge. Installation of the new is done in the reverse order. In a similar scheme, change the rubber mounts on the left and right side of the car. But you need to make a few comments to all of the above.

When carrying out work, be sure to look at the condition of all suspension elements. In particular, for the presence of damage or deformation of the levers. If those are present, then you can never make a convergence. Moreover, any master who deals with this procedure will simply wrap you up, say that you first change the suspension. And he's right, because you can not adjust the angles of the wheels on the dead suspension. No matter how well the adjustment has been carried out, after a few kilometers the corners will disintegrate, rubber will begin to break down.

Conclusion

In conclusion, I would like to note a few details that you need to know when replacing the silent blocks VAZ-2107. The most important thing is the need to replace not only the silentblocks, but also all the nuts that you unscrew during the repair. They are everywhere self-locking - they have on their threads small plastic inserts that fix the position on the bolt. Reuse of such nuts is not recommended. In addition, try the day before the start of the repair process all threaded connections with penetrating lubricant. If it does not help, you will have to use a gas canister, with which you need to warm up the carving.
