You can Select Your Vehicle to check if HG9Z-18124-J fits your vehicle.

Examine the shock for signs of fluid leakage. Check the piston rod for signs of pitting along its entire length, and check the shock body for signs of damage. Test the operation of the shock, while holding it in an upright position, by moving the piston through a full stroke, then through short strokes of 2 to 4 inches. In both cases, the resistance felt should be smooth and continuous. If the resistance is jerky or uneven, or if there is any visible sign of wear or damage, replacement is necessary.

Tighten the mounting bolts/nuts to the torque.

Start by parking the vehicle on level ground, turning off the engine, setting the parking brake, and ensuring proper tire pressures.

Tighten the mounting fasteners to the torque. Note: Any rear suspension fasteners should be replaced with new fasteners on assembly and should only be tightened with the hub raised to a height of 15.5 inches from the hub center to the center of the fenderwell.
