Suspension Strut / Shock Absorber: Testing and Inspection
CHECK AND ADJUSTMENT
Coil spring
If loading is normal and vehicle attitude is not, check for spring damage, spring sag, or non-standard replacement springs.
Struts
Bounce test the vehicle at each front corner and at the rear bumper to check the strut function. Damping action should be positive and uniform all
around.
Inspect the struts for evidence of oil leakage. A thin film is normal. Check the rear strut upper bushing by shake testing with the vehicle raised just
enough to unload the struts (wheels still on the ground). Any looseness is indicative of worn or deteriorated bushings, which must be replaced.
Lower arm
Check the following points, repair or replace if necessary.
1. Loose installation bolts and nuts.
2. Deformation or cracks in the lower arm.
Tension rod
Check the following points or replace if necessary.
1. Looseness of the installation bolts and nuts.
2. Worn or deteriorated bushing.
