How to service and repair the lower control arm on 2003 Ford Mustang?

Begin the lower control arm servicing process by applying markings to the rear shock absorber relative to the protective sleeve when the vehicle rests on level ground at the parking curb height. The first step involves removing the muffler assembly together with the rear spring. Start by detaching the lower suspension arm along with its bushing from their body attachment points by removing the old bolt and nut then removing the lower arm. The new lower suspension arm with bushing should be installed onto the body attachment while using a fresh bolt and nut but avoid tightening at this moment. When installing the rear spring you should first verify the suspension height reaches curb level then complete the bolt tightening procedure on the lower suspension arm and body-bushing connection. Finally, reinstall the muffler assembly. Proper retention of important suspension components can be achieved by following torque values and by using new parts with matching part numbers during required replacements.
