Remove the cap on the shock tower and remove the fasteners that attach the upper end of the shock to the frame. Loosen the front wheel lug nuts. Raise the front of the vehicle and support it securely on jackstands. Remove the front wheels. Disconnect the stabilizer bar link from the shock assembly. Remove the fasteners attaching the lower end of the shock absorber to the lower control arm. Pull down on the lower control arm and remove the shock absorber towards the rear of the vehicle.

To check the shock absorbers, park the vehicle on level ground, turn off the engine, and set the parking brake. Push down at one corner of the vehicle and release it, noting the movement of the body. It should stop moving and come to rest in a level position within one or two bounces. If the vehicle continues to move up and down or fails to return to its original position, a worn or weak shock absorber is likely the reason. Repeat this check at each of the three remaining corners of the vehicle.

Remove the cap on the shock tower and remove the fasteners that attach the upper end of the shock to the frame. Loosen the front wheel lug nuts.

When servicing the left shock absorber, remove the rubber hose between the fuel filler neck and the gas tank and move the filler neck aside. If dealing with dual exhaust or the right shock absorber, lower the exhaust and support it with jackstands or another jack. Place a floor jack under the rear differential to support the suspension and subframe. Support the spring link with a floor jack and wood block and remove the fasteners attaching the upper end of the shock absorber to the frame. Slowly lower the floor jack supporting the spring link. Remove the fasteners at the lower end of the shock and mark the subframe in relation to the chassis before removing the front and rear subframe fasteners on the side being worked on.
