(NAPSI)-Most owners know their vehicles require routine maintenance, including periodic inspection of their batteries, spark plugs, tires, windshield wipers, filters and fluids. But often the parts drivers can't see-such as shock absorbers and struts, located under the vehicle-don't get the attention they deserve.
In addition to causing an uncomfortable ride and poor handling, weak shocks may cause changes in vehicle ride height. This may lead to increased wear on other suspension components-including tires, ball joints and springs-which could cause premature component failure in extreme cases. These components are often more expensive to replace than the shocks themselves.
"Shocks and struts are the only devices on your vehicle designed to help reduce up and down movement," said Sherry Allen, product specialist, ACDelco Suspension Systems. "Reducing this movement can offer many benefits, such as improved comfort, control and handling. ACDelco shocks and struts fit 95 percent of vehicle models from the 1980s on."
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.
