You can Select Your Vehicle to check if 7W7Z-18124-C fits your vehicle.

Have an assistant grasp the lower edge of the tire and move the wheel in and out while you look for movement at the steering knuckle-to-control arm ball joint. If any movement is detected, the suspension ball joint(s) must be replaced.

Note the order of installation for any bushings and grommets above and below the upper control arm. Inspect these parts for cracks, tears, and deterioration, replacing them as necessary.

Ensure that all air is expelled from the new shock absorber by extending and compressing it several times before placing the inner washer and rubber insulator on the shock piston rod. Insert the rod through the upper mounting hole in the frame, attach the outer insulator, washer, and a new stud retaining nut on the upper side of the frame, making sure the insulator "pilots" engage properly in the frame attaching holes. Tighten the nut to the specified torque.

Removal starts by removing the shock absorber upper attaching nut, washer, and bushing to detach the upper end of the shock absorber. For upper balljoint replacement on 1992 and later models, it's crucial to mark the location of the alignment marks on the adjustment cams before removing the two retaining nuts.

Park the vehicle on level ground, turn off the engine, and set the parking brake. Check 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.
