You can Select Your Vehicle to check if 3W3Z-18125-AA fits your vehicle.

If any free play is noted, check the steering gear mounts and the tie-rod ends for looseness. Verify the steering gear mount bolt tightness. If the tie-rods are loose, the ball joints may be worn.

Compress the shock absorber to clear the hole in the frame, and then remove the inner insulator and washer from the upper retaining stud. Some models may have shocks with a plastic dust tube, which can be loosened using a wrench. Remove the lower retaining nut and the lower shock absorber mounting stud from the mounting bracket to complete the removal process.

During installation, ensure all air is expelled from a new shock absorber (for 2002 and earlier models), install all bushings and grommets in the order of removal, and use 5116-18 locknuts on the self-tapping bolts if the threads in the lower control arm are stripped or damaged. Tighten all fasteners to the specified torque, with locknuts torqued to the same specification as the bolts.
