Mercury F7AZ-18125-FA Kit - Shock Absorber

You can Select Your Vehicle to check if F7AZ-18125-FA fits your vehicle.

The steering linkage and suspension components should be checked periodically as worn or damaged components can lead to excessive tire wear, poor ride quality, reduced fuel economy, and compromised vehicle handling. To check the shock absorbers, park the vehicle on level ground, turn off the engine, and set the parking brake. Push down at each corner of the vehicle and observe if it stops moving and returns to a level position within one or two bounces. If the vehicle continues to move or fails to return to its original position, it may indicate worn or weak shock absorbers. Raise the vehicle and inspect the shock absorbers for fluid leakage, ensuring that any fluid noted is from the shocks and not from another source. Replace the shocks as a set if leakage is present. Additionally, check the shock absorbers for secure mounting and any signs of damage. For the steering and suspension check, visually inspect the components for damage, leaks, and worn seals, boots, and fittings. Clean the lower end of the steering knuckle and have an assistant move the wheel in and out while checking for movement at the steering knuckle-to-control arm balljoint. If there is any movement, the suspension balljoint(s) should be replaced. Grasp each front tire at the front and rear edges, push in at the front and pull out at the rear to feel for play in the steering system components. If any play is noted, check the steering gear mounts and tie-rod ends for looseness. Finally, check the steering gear mount bolt tightness and if the tie-rods are loose, the balljoints may be worn.

The steering knuckle should be inserted into the lower mounting flange of the strut assembly, and the two bolts should be installed. If recommended, new bolts and nuts should be used and tightened to the specified torque.

The vehicle should be raised and securely supported on jackstands.

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.
