To remove the model of a coil-over shock absorber, start by loosening the front wheel nuts which hold together its lug, lift up the automobile and remove it tire. Use a floor jack to support the external end of lower control arm and detach the tie-rod end from steering knuckle. Remove top mounting nuts and two bolts that attach bottom of shock absorber to lower control arm. Pull it out from below. To install, reverse removal steps for installing new shocks and tighten fasteners as per their torque specifications. If equipped with a suspension control system, reconnect electrical plug at top of shock absorber. For torsion bar models, follow same steps but back up wrench on stem is used for removing upper mount nut as well as related hardware. Observe direction in which bolt points while removing the lower mounting nut and bolt. Reverse removal steps when installing making sure that lower mounting bolt is pointing exactly in the same spot it did before.

If the vehicle is equipped with a ride control system, the electrical connector and the airline should be disconnected from the shock absorber.

Start by loosening the front wheel lug nuts, raising the vehicle, and removing the wheel.

Visually inspect the steering and suspension components (front and rear) for damage and distortion. Look for damaged seals, boots, bushings, and any leaks.

The outer CV boot should be inspected more frequently because it wears out sooner due to constant pivoting following the steering action of the front hub.

The rear axle should be supported with a floor jack placed under the axle tube closest to the shock absorber being removed.
