ACDelco, a global leader in automotive replacement parts and service, offers the following vehicle maintenance quiz on shock absorbers:
Q: Is there an obvious sign, like a noise or a jolt, that shock absorbers make when they wear out and need to be replaced?
A: Not really. Shocks wear out gradually, so an incremental loss of handling, control or ride performance may not even be noticeable to the vehicle owner. The vehicle's shocks should be inspected every time the vehicle comes in for any service.
Q: Which of the following are indications that a vehicle's shocks may need to be replaced?
a) Vehicle continues to bounce after hitting a road bump
b) Vehicle may take longer to stop
c) Vehicle nose-dives when braking
d) Vehicle ride is shaky or bumpy
e) Vehicle sways or leans on turns
A: All five are symptoms of worn-out shocks. Because shocks deteriorate slowly, most drivers say that until the new shocks are installed, they don't realize what a significant difference shocks make in comfort, control and handling.
Q: Is there any physical evidence that may indicate a vehicle's shocks need replacing?
A: The two most common physical signs are: 1) cupping of the tires; that is, fairly regular, small patches of rubber dug out around the tire's circumference, and 2) oil leaking from the shocks. ACDelco encourages drivers to have their vehicle's suspension system thoroughly inspected every time the vehicle comes in for any service by a service center that has ASE-certified technicians.
