You can Select Your Vehicle to check if 9T4Z-18125-A fits your vehicle.

To maintain balanced characteristics on both sides of the vehicle, it's advisable to replace components on both sides simultaneously.

1. Loosen the wheel lug nuts. 2. Raise the vehicle and support it securely on jack stands. 3. Remove the wheel. 4. Unbolt the brake hose bracket from the shock absorber. 5. Remove the wheel speed sensor and detach the wiring harness by removing the clamp bracket bolt. 6. On 2015 and later models, remove the stabilizer bar link nut and disconnect the link from the strut. 7. Support the control arm with a floor jack. 8. Unscrew the nuts securing the strut to the steering knuckle. 9. Tap the bolts out with a hammer. 10. Use the floor jack to lower the knuckle to allow room to remove the shock absorber/coil spring assembly, being careful not to overextend the inner CV joint.

Attempt to move each control arm up and down to check for play in the ball joints. If there is play, replace the worn ball joint.

Assess tire wear patterns, inflation, and inspect the universal joint, steering gear housing, dust boots, boot clamps, tie-rod ends, and all suspension and steering components for damage, wear, loose bolts, and deteriorated rubber bushings.

If the shock absorber was replaced on 2015 and later models, install the upper mounting bracket to the shock absorber and tighten the piston rod nut to the torque.

1. Guide the assembly up into the fenderwell. 2. Align the previously made match marks. 3. Insert the upper mounting studs through the holes in the body. 4. Once the studs protrude, install the new nuts to prevent the shock from falling back through, but don't tighten them yet.

If the shock absorber is going to be replaced on 2015 and later models, remove the piston rod nut and separate the upper mounting bracket.

Signs of wear include leaking fluid, loss of damping capability, or issues like sagging or cracked coil springs.
