You can Select Your Vehicle to check if 22872084 fits your vehicle.

To reassemble, if the lower insulator is being replaced, it should be set into position with the dropped portion seated properly.

Install the wheel and lug nuts, then lower the vehicle and tighten the lug nuts to the specified torque.

Start by loosening the rear wheel lug nuts and raising the rear of the vehicle.

If leakage is noted, replace the struts/shocks as a set.

Guide the strut into position and secure the fasteners to prevent the strut from falling back through. Slide the steering knuckle into the strut flange and insert the two bolts, matching the previously marked position of the strut to the steering knuckle. Tighten the nuts to the specified torque. Reattach the brake hose bracket and stabilizer bar link.

Park the vehicle on level ground, turn the engine off and set the parking brake. Check the tire pressures. Push down at one corner of the vehicle, then release it while noting the movement of the body. It should stop moving and come to rest in a level position within one or two bounces. If the vehicle continues to move up-and-down or if it fails to return to its original position, a worn or weak shock absorber is probably the reason. Repeat the above check at each of the three remaining corners of the vehicle.

To reassemble, if the lower insulator is being replaced, it should be set into position with the dropped portion seated properly. The dust boot should be replaced, and the damper rod should be extended, and the rubber bumper installed. The coil spring should be placed onto the lower insulator, with the end resting properly. The upper spring seat and top mount should be installed, aligning them correctly. The damper nut should be tightened to the specified torque, and the spring compressor tool can be removed.

Proceed to remove the upper and lower shock absorber mounting bolts.
