You can Select Your Vehicle to check if F2GZ-18125-F fits your vehicle.

From inside the rear cargo area, remove the interior quarter trim panel. Remove the upper shock absorber mounting nuts. Loosen the wheel lug nuts, raise the vehicle and support it securely on jackstands. Block the front wheels to prevent the vehicle from rolling and remove the rear wheel. Support the rear lower control arm with a floor jack, then remove the lower shock absorber nut and bolt. Maneuver the shock out of the vehicle. On 2015 and later models, if the shock absorber is going to be replaced, remove the piston rod nut and separate the upper mounting bracket. On 2015 and later models, if the shock absorber was replaced, install the upper mounting bracket to the shock absorber and tighten the piston rod nut to the torque. New shock absorbers are gas-filled and come compressed and retained with a fiberglass strap. Do NOT remove the strap until the shock is installed. When installing the shock absorber on 2014 and earlier models, install the upper and lower shock mounting fasteners but leave them loose until after the vehicle has been lowered or the suspension raised with a floor jack to simulate normal ride height. Tighten the lower bolt and nut to the specified torque with the full weight of the vehicle on the ground, then tighten the upper mounting nuts to the specified torque.

Ensure the vehicle is parked on level ground with the engine off and the parking brake engaged while verifying tire pressures.

To reassemble, install the lower spring seat, bump stop, and dust boot onto the shock absorber, followed by the spring and upper mount/upper seat, aligning the arrow or notch appropriately.

Have the front end alignment checked, and if necessary, adjusted.

Examine all components for wear or damage, replacing them as necessary. Check the shock for fluid leakage, inspect the piston rod for pitting, and assess the shock body for damage.

Push down on each corner of the vehicle and observe its body movement, expecting it to return to a level position within one or two bounces. Persistent bouncing or failure to level may indicate worn or weak shock absorbers.

New shock absorbers are gas-filled and come compressed and retained with a fiberglass strap. Do NOT remove the strap until the shock is installed.
