Shock Absorber and/or Coil Spring Inspection
1) Inspect shock absorber for oil leakage. If shock absorber is found faulty, replace it as an assembly unit, because it can not be disassembled.
2) Shock absorber function check
Check and adjust tire pressures as specified.
Bounce body three or four times continuously by pushing front end on the side with shock absorber to be checked. Apply the same amount of force at each push and note shock absorber resistance both when pushed and rebounding.
Also, note how many times vehicle body rebounds before coming to stop after hands are off. Do the same for shock absorber on the other side.
Compare shock absorber resistance and number of rebound on the right with those on the left.
And they must be equal in both. With proper shock absorber, body should come to stop the moment hands are off or after only one or two small rebounds. If shock absorbers are suspected, compare them with known good vehicle or shock absorber.
3) Inspect for damage or deformation.
4) Inspect for cracks or deformation in spring seat.
5) Inspect for deterioration of bump stopper.
6) Inspect shock absorber mount for wear, cracks or deformation. Replace any parts found defective in Steps 2) – 6).
