Ensure the vehicle is parked on level ground with the engine off and the parking brake engaged while verifying tire pressures.

New shock absorbers are gas-filled and come compressed and retained with a fiberglass strap. Do NOT remove the strap until the shock is installed.

1. Loosen the wheel lug nuts. 2. Raise the vehicle and support it securely on jack stands. 3. Remove the wheel. 4. Unbolt the brake hose bracket from the shock absorber. 5. Remove the wheel speed sensor and detach the wiring harness by removing the clamp bracket bolt. 6. On 2015 and later models, remove the stabilizer bar link nut and disconnect the link from the strut. 7. Support the control arm with a floor jack. 8. Unscrew the nuts securing the strut to the steering knuckle. 9. Tap the bolts out with a hammer. 10. Use the floor jack to lower the knuckle to allow room to remove the shock absorber/coil spring assembly, being careful not to overextend the inner CV joint.

Utilize coil spring compressor tools to fully engage and compress the spring until tension is relieved from the upper mount.

Scrutinize suspension arm bushings for deterioration.

In the engine compartment, mark the relationship of one of the mounting studs to the body, then remove the four upper mounting nuts.

With the spring compressed, install the rod nut, ensuring the ends of the spring fit into the recessed portion of the seats and maintaining the specified gap. Tighten the nut to the prescribed torque while keeping the position at both ends consistent.

Loosen the wheel lug nuts, raise the vehicle and support it securely on jackstands. Block the front wheels to prevent the vehicle from rolling and remove the rear wheel.
