In the rear compartment of the car, open the upper shock nut access panel in the trim cover (hatchbacks only) and remove the upper shock nut. The upper shock stud must be kept from turning while the nut is loosened. Raise the rear of the car enough to take the weight off of the suspension, but do not lift the tires off the ground. Support the car with jackstands placed at suitable locations under the car's frame. Do not place them under the rear axle. If more clearance is needed under the car, the car can be raised higher, but then the rear axle must also be supported with jackstands. Remove the lower shock attaching bolt and nut and remove the shock. It may be necessary to use a screwdriver to pry the lower end of the shock out of its mounting bracket. The shock should be compressed and then extended its full length a few times to check for any free movement of the shaft, noise, or fluid leakage. If any of these conditions are found the shocks should be replaced with a new set. To install, extend the shock to its full length and place it in its lower mount. Then feed the lower attaching bolt through the mount and shock and install the nut loosely. Lower the car enough to guide the shack's upper stud through the body opening and loosely Install the upper attaching nut. Tighten the lower attaching nut, torquing it to specs. Lower the car completely and torque the upper attaching nut to specs. Again the upper shock stud must be kept from turning while tightening the upper nut. On hatchback models, close the access panel in the trim cover.
