Mercury 3U2Z-18124-BJ Shock Absorber Assy - Front

You can Select Your Vehicle to check if 3U2Z-18124-BJ 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.

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.

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.

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.

Start by raising the rear of the vehicle and securely supporting it on jackstands.
