To reassemble, install the lower spring seat, bump stop, and dust boot onto the shock absorber, followed by the spring and upper mount/upper seat, aligning the arrow or notch appropriately.

Check the shock body for leaking fluid, dents, cracks, and other obvious damage that would warrant replacement. Check the coil spring for chips or cracks in the spring coating. Inspect the spring seat for cuts, hardness, and general deterioration.

The initial steps include loosening the wheel lug nuts, raising the vehicle, and securely supporting it on jack stands while ensuring the front wheels are blocked to prevent rolling. The wheel also needs to be removed for access to the suspension components.

1. Guide the assembly up into the fenderwell. 2. Align the previously made match marks. 3. Insert the upper mounting studs through the holes in the body. 4. Once the studs protrude, install the new nuts to prevent the shock from falling back through, but don't tighten them yet. 5. Use the jack to position the steering knuckle. 6. Install the two lower mounting bolts and nuts. 7. Tighten the nuts to the specified torque. 8. Install the wheel and lug nuts. 9. Lower the vehicle and tighten the lug nuts to the specified torque. 10. Finally, tighten the upper mounting nuts to the specified torque.

For 2010 and earlier models, the removal steps include removing the brake caliper, brake disc, brake cable bracket, stabilizer bar link, and wheel speed sensor. On all-wheel drive models, the inner and outer drive axle/hub nuts need to be removed and the drive axle needs to be separated from the hub and bearing using a drive hub remover.

The springs and related components can be individually replaced.
