GM 89047814 Rear Suspension Strut Kit

To remove the strut, start by moving the side trim in the trunk compartment to expose the strut upper mounting fasteners. Loosen the mounting fasteners without removing them and pull off the rubber cap on top of the strut if it is equipped. Next, loosen the rear wheel lug nuts, block the front wheels, and raise the rear of the vehicle on jackstands. Remove the rear wheels and support the rear suspension with a floor jack. Detach the stabilizer bar link from the strut and mark the relationship of the strut to the knuckle. Remove the strut-to-knuckle nuts and bolts, separate the strut from the rear knuckle, and remove the upper mounting nuts to take out the strut. Make sure to secure the rear knuckle to prevent damage. To inspect the strut, check for leaking fluid, dents, cracks, and other damage. Also, inspect the coil spring for chips or cracks in the coating and the spring seat for cuts or deterioration. If any issues are found, proceed to the strut disassembly procedure. For installation, guide the knuckle into the strut flange and place the upper part of the strut in position to mount to the body. Install the upper mounting nuts finger-tight and use a soft-face hammer or mallet to install the bolts. Align the marks made and tighten the nuts to the specified torque. Install the stabilizer bar link, wheel, and lug nuts, then lower the vehicle and tighten the lug nuts. Finally, tighten the upper mounting nuts to the specified torque and have the wheel alignment checked and adjusted if necessary.

Start by loosening the lug nuts on the front wheels and raising the vehicle with jackstands. Remove the wheels afterward.
