To disassemble the strut and spring assembly, you need to mount the strut clevis bracket portion in a vise and mark the components for reassembly. Then, install a spring compressor on the spring and compress it to relieve pressure from the upper mount. While holding the damper shaft, loosen the shaft nut with a socket. Remove the nut and upper mount, inspecting the pivot bearing and upper spring seat for damage. Lift the compressed spring from the assembly and remove the dust boot from the damper shaft. Slide the rubber bumper off the damper shaft and check the lower spring isolator for damage.

To simulate normal ride height, the rear suspension should be raised with a floor jack positioned under the knuckle.

Slowly release tension from the spring by backing off the spring compressor. Ensure the spring has settled in the locator holes and the brackets/mounts are not twisted or off-center.

Before starting any work, it is recommended to explore all options. The strut body cannot be serviced and must be replaced if there is a problem. However, complete strut assemblies with springs may be available on an exchange basis, which can save time and effort. It is important to check the cost and availability of parts before disassembling the vehicle.

After simulating normal ride height, the lower mounting bolt should be tightened, the wheel and lug nuts should be installed, and the vehicle should be lowered and the lug nuts tightened. On 2014 and earlier models, the shock absorber upper mounting nuts should also be tightened. Finally, the trim panels in the trunk should be reinstalled.

Hold the damper shaft with a wrench and remove the damper shaft nut.
