Mercury 5U2Z-18V125-VF Kit - Shock Absorber

You can Select Your Vehicle to check if 5U2Z-18V125-VF fits your vehicle.

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.

The initial steps are to loosen the front wheel lug nuts and raise the vehicle, supporting it securely on jackstands. Then, remove the wheel and the disc brake caliper, hanging it out of the way with wire.

Locate the upper retaining nut for the shock absorber on top of the frame and remove the nut, washer, and insulator. Compress the shock absorber to clear the hole in the frame and remove the inner insulator and washer. On certain models, open the trunk, remove the side trim panel, and remove the upper mounting nut from the shock absorber rod. Remove the lower retaining nut or bolt and remove the shock absorber from the vehicle.

It may indicate worn or weak shock absorbers.

The shock absorber should be removed through the hole in the lower control arm.

Visually inspect the steering system components for damage and distortion. Look for leaks and damaged seals, boots, and fittings.

After detaching the upper end, raise the vehicle and securely support it on jackstands. Remove the self-tapping bolts attaching the lower end of the shock absorber to the lower control arm, thereby detaching the lower end from the lower A-arm. Finally, remove the shock absorber through the hole in the lower control arm.

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.

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.
