You can Select Your Vehicle to check if F8VZ-18124-AA fits your vehicle.

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.

On models with air suspension, turn off the air suspension switch and disconnect the height sensor connector link before allowing the rear suspension to hang past its normal point of full rebound. Raise the rear of the vehicle and support it securely on jackstands. If the vehicle is a pre-1992 model with automatic leveling rear suspension and coil springs, allow the rear axle to hang free until the shock absorbers are finished venting through the compressor. Support the rear axle with a floor jack to prevent it from dropping when the shock absorber is disconnected. If removing an air-assisted shock absorber, detach the air line.

If the threads in the lower control arm are stripped or damaged, locknuts should be installed on the self-tapping bolts.

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.
