Mercury 7W7Z-18125-B Shock Absorber Assembly

You can Select Your Vehicle to check if 7W7Z-18125-B fits your vehicle.

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

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.

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.

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

For 2003 and later models, remove the three shock absorber upper mounting nuts, the brake caliper, and the brake disc. Additionally, remove the upper and lower stabilizer bar links. Remove the upper balljoint nut and separate the control arm from the steering knuckle. Finally, remove the lower mounting bolt and the shock absorber/coil spring assembly from the front end of the vehicle.

If the vehicle has an air suspension, turn the air suspension switch to On, start the engine, and let the compressor inflate the air suspension springs before driving.
