During a trip malfunction of shock-absorbers can be determined by the following signs:

 – the long fluctuations of a body caused by roughnesses of the road;
 – a body swing on two following one after another road hillocks;
 – jumping of wheels on the normal road;
 – breakthrough of the car when braking (it can be caused also by other reasons);
 – a road incontience on turns, a drift;
 – strong knocks;
 – the increased wear of tires with bald places on a protector.

The shock-absorber can be checked by effort of a hand. Exact definition of degree of wear is possible only by means of devices: a rod tester (the shock-absorber is not removed) or the test car of shock-absorbers.

Check of the shock-absorber by effort of a hand

1. Remove the shock-absorber.
2. Stretch 3 times in assembled form and squeeze the shock-absorber. During all course the shock-absorber has to move evenly hard, without breakthroughs, besides, without undesirable noise.
3. Completely move a shock-absorber rod, then release it. The rod has to move forward outside with a uniform speed.
4. At excellent job insignificant traces of oil are not the basis for replacement of the shock-absorber.
5. Replace the shock-absorber at big loss of oil.
6. Put the shock-absorber.

Utilization of shock-absorbers


The shock-absorber contains mineral oil, and, for example, in Germany, according to the law on waste its contents are given together with engine oil.

1. To merge oil from the shock-absorber, it is necessary to produce previously from it nonpoisonous gas without color and a smell, having drilled at distance 20 mm from the basis a hole with a diameter of 3 mm.
2. To merge oil, it is necessary to drill a hole with a diameter of 5 mm at distance of 60 mm from the basis.
