Start by unscrewing the rear wheel nuts, lift the rear of your car, place jackstands under it, and block the front wheels to make sure the car stays put. Pull out the wheel and lower the trunk panel to make it easy to reach the shock absorber top mounting point in the trunk. Place a jack underneath the
Trailing Arm, where it connects to the knuckle, to stabilize the lower arm while you work. Keep the suspension shaft steady by tightening a hex tool on its lower end as you loosen the upper mounting nut holding the shock absorber. First, unscrew the lower mounting bolt, then easily pull out the shock absorber. Look over the shock body for signs of fluid leaks, dings, cracks, and other visible damage. See how much work you need to do to fix or replace it. Bring the new shock absorber into the fender area and slip the damper through the body opening - keep the damper rod visible - and fasten the bushing, washer, and nut to stop the assembly from sinking back below, using fresh mounting bushings for better stability. Place the shock absorber on the trailing arm, lift the trailing arm to normal ride height with the jack, secure the shock both on top and bottom by hand-tightening the relevant bolts and nut. Last, attach the tire, thread on all lug nuts, let the car return to the ground, and tighten the lug nuts.
