    Q:
    How to remove and install a front coil-over or torsion bar shock absorber module? Posted by Customer
    A:
    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.
