Loosen the rear wheel lug nuts, raise the rear of the vehicle, support it securely on jackstands, and remove the wheels. Position a floor jack under the coil spring seat portion of the rear suspension beam, then raise the suspension arm slightly. Remove the shock absorber lower bolt. Carefully lower the suspension arm using the floor jack until the coil spring is fully extended. Remove the coil spring, the rubber mount, and the rubber seal. Installation is the reverse of removal, ensuring to tighten the shock absorber lower mounting bolt and the wheel lug nuts to the specified torque.

Set the new lower insulator into position, extend the damper rod to install the dust boot, place the coil spring onto the lower insulator ensuring the end rests correctly, then install the upper insulator and spring seat, aligning the marks or arrows outward.

Inspect the coil spring for chips or cracks in the coating, which could lead to premature failure due to corrosion, and examine the spring seat for cuts, hardness, and general deterioration.
