Loosen the rear wheel lug nuts, then raise the rear of the vehicle and support it securely on jackstands while blocking the front wheels to prevent rolling. Remove the wheel and support the lower rear suspension arm with a floor jack placed under the coil spring pocket. Take off the shock absorber upper mounting nut and then remove the lower mounting bolt and nut to detach the shock absorber. For installation, reverse the removal process, ensuring to raise the lower suspension arm with the jack to simulate normal ride height before tightening the mounting fasteners to the specified torque. Finally, install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the specified torque.
