You can Select Your Vehicle to check if 13345954 fits your vehicle.

To remove the rear wheels, start by loosening the lug nuts and blocking the front wheels to prevent the vehicle from rolling. Then, raise the rear of the vehicle and secure it on jackstands. Once the vehicle is properly supported, remove the rear wheels. Next, use a floor jack to support the rear axle on the side you are working on, positioning the jack head under the coil spring pocket. Proceed to remove the shock absorber upper and lower mounting bolts. Take a close look at the shock for any signs of fluid leakage or damage to the shock body. Test the operation of the shock by moving the damper shaft through a full stroke and short strokes of 2 to 4 inches. The resistance should be smooth and continuous; if it is jerky or uneven, or if there is any visible wear or damage, the shock needs to be replaced. To install the shock, simply reverse the removal steps, using new bolts and tightening them to the proper torque.

Proceed to the strut disassembly procedure.

Yes, there may be the option to replace the entire strut assembly with springs on an exchange basis, which can save time and effort.
