TESTING



Visually inspect the shock absorber. If there is evidence of leakage and the shock absorber is covered with oil, the shock is most likely defective and should be replaced.

If there is no sign of excessive leakage (a small amount of weeping is normal), bounce the truck at one corner by pressing down on the bumper and releasing it. When you have the truck bouncing as much as you can, release the bumper. The truck 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.
