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 lower rear suspension arm and raise it slightly. Mark the relationship of the adjusting cam to the subframe before loosening the bolt for the rear lower suspension arm at the subframe. Remove the nut and bolt for the lower rear suspension arm at the knuckle. Carefully lower the suspension arm using the floor jack until the coil spring is fully extended, then remove the coil spring, the rubber mount, and the rubber seal. For installation, raise the lower suspension arm with a floor jack until it is at normal ride height, then tighten the suspension arm bolt and nuts to the specified torque, ensuring the marks on the adjusting cam and the subframe are aligned before tightening the fasteners. Finally, tighten the wheel lug nuts to the specified torque.
