Loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands while blocking the front wheels to prevent rolling, then remove the wheel. Support the rear suspension arm "B" with a floor jack and a board to protect it from damage, raising the jack slightly to relieve spring pressure from the shock absorber lower mount, approximately 1.5 to 2 inches. From underneath the vehicle, remove the lower two bolts from the shock absorber bracket, followed by the upper mounting bolt. Take out the shock absorber, then remove the lower mounting bracket and separate the shock absorber from it, ensuring to install the bracket on the replacement shock absorber. For installation, reverse the removal steps and tighten the mounting fasteners, raising the lower arm with a floor jack to simulate normal ride height before tightening the shock absorber-to-lower mounting bracket fasteners.
