Remove the lower retaining nut or bolt and remove the shock absorber from the vehicle.

The floor jack can be removed from under the control arm.

Park the vehicle on level ground, turn off the engine, and set the parking brake. Check tire pressures. Push down at one corner of the vehicle, then release it while noting the movement of the body. It should stop moving and come to rest in a level position within one or two bounces.
