GM 25793745 Rear Shock Absorber Assembly

To remove the rear wheels, start by loosening the lug nuts and securing the front wheels with chocks. Then, raise the rear of the vehicle and support it with jackstands. Once the vehicle is secure, 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, follow the reverse steps of removal, using new bolts and tightening them to the specified torque.

To remove the strut, start by loosening the wheel lug nuts and raising the vehicle on jackstands. Then, remove the wheel and disconnect the stabilizer bar link from the strut. If the vehicle is equipped with ABS, detach the ABS harness from the strut.
