Loosen lug nuts, lift vehicle, and remove rear wheels. Support trailing arm with a jack, remove damper cover and shock absorber mounting nuts. Remove lower shock absorber bolt, lower jack and arm, and remove shock absorber/spring assembly. Installation is reverse of removal. Before tightening lower bolt, raise trailing arm to simulate ride height and tighten all fasteners.

Guide the shock absorber assembly into the fenderwell and insert the upper mounting studs through the body holes. Install the nuts to prevent the assembly from falling back through, without fully tightening them yet. Enlist assistance due to the weight of the shock absorber. Insert the lower end of the shock absorber into the damper fork, ensuring alignment between the tab on the shock body and the slot in the fork. Connect the damper fork to the lower control arm, simulate normal ride height by raising the lower control arm with the floor jack, then tighten the self-locking nut and the damper fork pinch bolt. Reconnect the stabilizer bar to the control arm, secure the brake hose to its bracket, and tighten the bolt firmly. Install the wheel, tighten the lug nuts, lower the vehicle, and further tighten the lug nuts. Finally, complete the process by tightening the upper mounting nuts.

Mount the shock absorber assembly in a vise, line the vise jaws with wood or rags to prevent damage to the unit and don't tighten the vise excessively. Mark the relationship of the damper mounting base to the spring.
