- A) slow return of the body to its original position when driving on rough roads;
- b) increasing body vibrations when the wheels collide with adjacent road irregularities;
- V) bouncing wheels and on a flat road surface;
- G) difficult stop (uncontrollability) car when braking (it may be due to other reasons);
- d) instability and skidding of the car when cornering;
- e) thumps while driving;
- and) increased tire wear, accompanied by tread wear.
The performance of the shock absorber can be checked manually. However, an accurate check of the functioning of the shock absorber is possible only on a vibration stand (without removal from the car) or by using a special shock absorber diagnostic tool.
Manual shock absorber performance test
1. Remove shock absorber.
2. Hold the removed shock absorber in the mounting position. Pull the damper rod out at least 3 times and then push it back into the body. The shock absorber rod must move uniformly and without jerks along the entire length of the stroke. At the same time, there should also not be a stroke length to move equally smoothly and without jerks. At the same time, no extraneous noise should be heard (see illustration).
4.2 Pull the damper rod out and then push it back into the body
3. Push the shock absorber rod in completely and release it. Under the pressure of the fluid, the rod should itself return to its original position.
During normal functioning of the shock absorber, small traces of leakage of the damping fluid are not a reason to replace the shock absorber.
4. Replace shock absorber if fluid loss is significant.
5 Install a new shock absorber.
