Weak damping
- Check the left and right shock absorbers of the front suspension by vigorously shaking the corresponding corner of the body downwards
- The body rolls must be done with the same force. Note the shock absorber resistance during compression and rebound
- Compare the test results with a well-maintained vehicle that has good ride quality
- stroke. Both shock absorbers must provide the same resistance forces
Noise when operating suspension struts
..- Check the tightness of all threaded connections
- The noise may be caused by loose suspension strut fasteners
- If the fasteners are in order, you need to sharply rock the car to determine the source of extraneous noise in the suspension
- If possible, test drive the vehicle to identify any signs of malfunction
Leaks
- Raise the vehicle's wheels completely to inspect the shock absorber rod seal cover
- Check the shock absorber rod seals for signs of fluid leakage
- The presence of traces of working fluid ("sweating") does not indicate a malfunction of the shock absorber seals
- A small amount of working fluid seepage 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 consumption
- A leaky shock absorber is easily detected by traces of a strong leak of working fluid on the housing and seal cover. A faulty shock absorber should be replaced
