TESTING



There are 2 possible clues that the shock absorbers are worn and may need replacement. The first is how the vehicle rides and the second is how the shocks appear. The shocks should be checked if the ride of your vehicle has become increasingly bouncy or if oil is visible on the shock, indicating possible fluid leakage.

Visually inspect the shock absorber if trouble or wear is suspected. If the shock absorber is covered with oil and there is evidence of leakage, the shock is defective and should be replaced.

If there is no sign of excessive leakage (a small amount of weeping is normal) but the ride is still suspect, bounce the vehicle at one corner by pressing down on the rear bumper and releasing. When you have the vehicle bouncing as much as you can, release the fender or bumper. The vehicle should stop bouncing after the first rebound. If the bouncing continues past the center point of the bounce more than once, the shock absorbers are worn and should be replaced.
