Inspection & Adjustments: 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.
