Carefully lower the differential with the floor jack to remove the shock absorber. Installation is carried out in reverse, ensuring to follow the specified points like installing the lower shock absorber fasteners before raising the subframe, aligning the subframe with reference marks, using the appropriate length bolts, and tightening all suspension fasteners. Finally, have the wheel alignment checked and adjusted if necessary.

Installation is the reverse of removal. Tighten the mounting fasteners. Note: Raise the lower control arm with a floor jack to simulate normal ride height before lightening lower shock absorber mounting fasteners. Tighten the wheel lug nuts.

Worn or damaged suspension and steering linkage components can result in excessive and abnormal tire wear, poor ride quality and vehicle handling, and reduced fuel economy.

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.

In the steering and suspension check, visually inspect the components for damage and distortion, including seals, boots, bushings, and leaks. Examine the bushings where the control arms meet the chassis, the tie-rod ends, the ball joints, and the steering gear boots.

Inspect the shock absorber for leaking fluid, dents, cracks and other damage. Inspect the coil spring for chips and cracks which could cause premature failure. Inspect the spring seats for hardness and general deterioration.
