Mercury 9L8Z-18125-B Shock Absorber Assembly

You can Select Your Vehicle to check if 9L8Z-18125-B fits your vehicle.

Front suspension struts leaking fluid, damping loss, sagging or cracked springs if showed signs of wear should be disassembled and overhauled as needed. The individual replacement of springs and related components is possible. For balance maintainability, both sides' components should be replaced at once. The strut should be cleaned and mounted into a vise; the spring compressor tool will compress the spring. It is necessary to unscrew the retaining nut, remove top mountings, thrust bearing, spring seat, spring itself, boot, and bump stop to lower the vehicle down until its wheels touch the ground. Examine all components for wear and damage: replace parts if necessary. Check for fluid leakage on piston rod pitting and strut body damage. If there are issues with the operation-test it out; otherwise replace it anyway.

Reconnect the following components: Brake hose bracket to the strut. Speed sensor wiring harness bracket (if equipped with ABS). Stabilizer bar link to the strut bracket.

Access to the shock absorber upper mounting nut.

To reinstall the strut assembly, follow these steps: Guide the strut assembly up into the fender well. Align the previously made matchmarks. Insert the upper mounting studs through the holes in the body. Install the nuts to secure the strut in place. This may require assistance due to the weight and awkwardness of the strut.

During the inspection, the following parts of the strut should be examined: Strut for signs of fluid leakage. Strut piston rod for signs of pitting along its entire length. Strut body for signs of damage.

Nuts, upper retainer, bushing, and lower retainer.
