You can Select Your Vehicle to check if 3W7Z-18125-DA fits your vehicle.

Worn or damaged suspension and steering linkage components can result in excessive and abnormal tire wear, poor ride quality, vehicle handling issues, and reduced fuel economy.

Compress the shock absorber to clear the hole in the frame, and then remove the inner insulator and washer from the upper retaining stud. Some models may have shocks with a plastic dust tube, which can be loosened using a wrench. Remove the lower retaining nut and the lower shock absorber mounting stud from the mounting bracket to complete the removal process.

For 2003 and later models, remove the three shock absorber upper mounting nuts, the brake caliper, and the brake disc. Additionally, remove the upper and lower stabilizer bar links. Remove the upper balljoint nut and separate the control arm from the steering knuckle. Finally, remove the lower mounting bolt and the shock absorber/coil spring assembly from the front end of the vehicle.

After detaching the upper end, raise the vehicle and securely support it on jackstands. Remove the self-tapping bolts attaching the lower end of the shock absorber to the lower control arm, thereby detaching the lower end from the lower A-arm. Finally, remove the shock absorber through the hole in the lower control arm.

Lower the vehicle by removing the jackstands.

Visually inspect the steering system components for damage and distortion. Look for leaks and damaged seals, boots, and fittings.
