TESTING



Adjust the tire pressure before testing the shocks. If the truck is equipped with heavy duty equipment, this can sometimes be misleading. A stiff ride normally accompanies a stiff or heavy duty suspension. Be sure that all weight in the truck is distributed evenly.

Each shock absorber can be tested by bouncing the corner of the truck until maximum up and down movement is obtained. Let go of the truck. It should stop bouncing in 1-2 bounces. If not, the shock should be replaced.
