ABSTRACT:
A control arm adjustment mechanism includes a frame bracket connected to a vehicle frame with a bolt extending through the frame bracket. A cam is keyed to the bolt and has a spiraling eccentric slot with the guide tab extending through the eccentric slot so that rotation of the bolt causes the guide tab to track within the eccentric slot causing a displacement of the bolt and a connected control arm end. A nut is threaded onto the bolt so that when the nut is torqued, the bolt is prevented from sliding. To adjust control arm positioning relative to the frame, the nut is loosened without being completely removed, the bolt is rotated to align a selected indicator mark with the first guide tab and the nut is retorqued.
