Start by loosening the wheel lug nuts, raising the vehicle, and securing it with jackstands. Remove the wheel. Then, unbolt the brake hose from the shock absorber assembly and disconnect the stabilizer bar from the lower control arm. Position a floor jack beneath the lower control arm to provide support during shock absorber removal. Proceed to remove the damper fork pinch bolt and the damper fork-to-lower control arm bolt, detaching the fork from the shock absorber. Support the shock absorber and coil spring assembly, and take off the two upper mounting nuts, ensuring not to remove the larger center nut. Carefully remove the unit from the fenderwell.

Support the trailing arm with a floor jack, remove the damper upper cover (if equipped), remove the shock absorber upper mounting nuts, remove the shock absorber lower mounting bolt that attaches the lower end of the shock absorber to the lower arm, lower the jack and the lower arm and remove the shock absorber/coil spring assembly.

Following the tool manufacturer's instructions, install the spring compressor on the spring and compress it sufficiently to relieve all pressure from the damper mounting base. Remove the damper cap, unscrew the self-locking nut while holding the damper shaft with an Allen wrench to prevent it from turning, then carefully lift the compressed spring from the assembly and set it in a safe place. Slide the rest of the parts off of the damper shaft, install the bump stop, bump stop plate (if equipped), dust cover and dust cover plate onto the new damper unit, extend the damper shaft as far as it will go and slide the components down to the damper body, carefully place the coil spring onto the shock absorber body, with the end of the spring resting in the lowest part of the seat, install the spring mounting rubber, lower mounting rubber, damper mounting collar, damper mounting base, seal, upper mounting rubber, damper mounting washer and a new self-locking nut, before tightening the nut, align the previously applied marks on the mounting base and the spring, then tighten the self-locking nut, again using the Allen wrench to prevent the shaft from turning, remove the spring compressor, install the damper cap and install the shock absorber/coil spring assembly.
