For 2014 and earlier models, start by removing the trim panels from the sides of the trunk to access the shock absorber upper mounting fasteners. Then, loosen the rear wheel lug nuts, raise the vehicle, and support it on jackstands. Remove the rear wheels. In the trunk, remove the two nuts that hold the shock absorber to the vehicle body. If equipped, remove the trim panels covering the lower control arm. Finally, remove the shock absorber lower mounting nut and bolt to remove the shock unit. For 2015 and later models, raise the rear of the vehicle and support it on jackstands. Remove the wheels and the rear fenderwell splash shield. Use a floor jack to support the knuckle and raise it slightly. Remove the shock absorber lower mounting bolt. If necessary, loosen the fuel filler tube bolt and move the filler tube aside for better access to the shock upper mounting bolts. Remove the shock absorber upper mounting bolts and the shock absorber assembly from the vehicle. If needed, transfer the shock upper mount to the new shock and tighten the center nut. For all models, grease the lower mount with white lithium grease for easier installation and to prolong the life of the lower shock bushing. If you plan on removing the springs and overhauling the shock unit, follow the procedures. On 2014 and earlier models, ensure that the side of the upper mount that protrudes more is facing towards the outside of the vehicle. On 2015 and later models, tighten the shock absorber upper bolts. Raise the rear suspension with a floor jack positioned under the knuckle to simulate normal ride height, then tighten the lower mounting bolt. Install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts. On 2014 and earlier models, tighten the shock absorber upper mounting nuts. Finally, reinstall the trim panels in the trunk.

Loosen the lug nuts on the rear wheels and raise the vehicle on jackstands. Remove the rear wheels. Remove the rear shock absorber/coil spring assembly.

Marking the position helps ensure proper alignment during reassembly.

To reassemble the strut and spring assembly, you need to extend the damper rod and install the rubber bumper. Put the dust boot onto the damper and carefully place the coil spring onto the damper, aligning it with the reference marks made during disassembly. Install the upper spring isolator and seat, followed by the upper mount, and tighten the nut on the damper shaft. Loosen the coil spring compressor until the top coil is properly seated against the upper spring seat and upper mount. Finally, remove the tool from the coil spring and install the strut/spring assembly.

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

Before lowering the vehicle, the wheel and lug nuts should be installed and tightened. Additionally, the front end alignment should be checked and adjusted if necessary.

Some signs of wear include leaking fluid, loss of damping capability, and chipped, sagging, or cracked coil springs.
