You can Select Your Vehicle to check if 1W7Z-18125-CA fits your vehicle.

Inspect the shock absorber for leaking fluid, dents, cracks, and other damage. Examine the coil spring for chips and cracks that could lead to premature failure. Also, inspect the spring seats for hardness and general deterioration.

Depress the retainer ring(s) and pull the air lines free.

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.

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.

If any components of the assembly are worn or damaged, have the unit serviced by a qualified repair shop, or replace it with a rebuilt or new unit.

Raise the vehicle, support it securely on jackstands, and check the shock absorbers for evidence of fluid leakage. A light film of fluid is generally not a concern. If leakage is noted, replace the shocks as a set.
