Shock Absorber

TESTING



The function of the shock absorber is to dampen harsh spring movement and provide a means of controlling the motion of the wheels so that the bumps encountered by the wheels are not totally transmitted to the body of the truck and, therefore, to you and your passengers. As the wheel moves up and down, the shock absorber shortens and lengthens, thereby imposing a restraint on excessive movement by its hydraulic action.

A good way to see if your shock absorbers are working properly is to push on one corner of the truck until it is moving up and down for almost the full suspension travel, then release it and watch its recovery. If the truck bounces slightly about one more time and then comes to a rest, you can be fairly certain that the shock is OK. If the truck continues to bounce excessively, the shocks will probably require replacement.
