The front strut rods, also called the radius rod or control arm strut, serve to locate the lower control arm and prevent fore-and-aft movement. Except for impact damage, the rods rarely fail. The rubber bushings on each end are prone to fatigue and wear and may need to be replaced after a few years.
Loosen the rod-to-body bolt but don't remove it. Remove the nut at the control arm. This is sometimes easier said than done; the control arm bolt can be very tight. Once the front nut is loosened, the back mount may be removed and the rod placed on a workbench.To install:
If the bushings are to be replaced, press them free of their mounts and install the new ones. Reinstall the rod, attaching the rear bolt first. Make sure the front bushings seat properly in the control arm and that the front nut draws tight against its washer.
