Weak damping
- Check the left and right front suspension dampers by vigorously rocking the corresponding corner of the body down
- The pitching of the body must be done with the same effort. Note the resistance of the shock absorber in compression and rebound
- Compare test results with a serviceable car with good smoothness
- move. Both shock absorbers must provide the same resistance force
Noise during suspension strut operation
..- Check tightness of all screw connections
- Noise may be caused by loose suspension strut fasteners
- If the fasteners are in order, it is necessary to rock the car sharply to determine the source of extraneous noise in the suspension
- If possible, test the vehicle while driving to check for signs of a problem
Leaks
- Fully hang the car wheels to inspect the shock absorber rod seal cover
- Check shock absorber rod seals for signs of fluid leakage
- The presence of traces of the working fluid ("fogging") does not indicate a faulty shock absorber seal
- A slight seepage of the working fluid through the seals provides lubrication of the shock absorber rod. The initial amount of working fluid filled into the shock absorber is designed to compensate for such an expense
- A leaky shock absorber is easily detected by the traces of a strong leakage of the working fluid on the body and seal cover. Defective shock absorber should be replaced
