Before raising the vehicle, measure the distance from the ground to the bottom of the rear suspension arm and record the measurement. Loosen the rear wheel lug nuts, then raise the rear of the vehicle and support it securely on jackstands. Remove the rear wheels. Remove the rear suspension arm plastic shield fasteners and shield, if equipped. Place a floor jack with a wooden block under the rear suspension arm below the coil spring pocket and raise the arm approximately 1 inch, keeping the jack in this position. Remove the shock absorber upper and lower mounting nut/bolts, then take out the shock absorber from the brackets. Install the rear shock absorber into the mounting brackets, then install the nut/bolts and temporarily hand tighten them. Using the floor jack, raise the rear suspension arm to simulate the ride height previously measured. Once the rear suspension arm is at the correct ride height, tighten the mounting nuts and bolts to the specified torque. Finally, install the rear wheels and tighten the lug nuts to the specified torque.
