ABSTRACT:
Method and apparatus are provided for factory pre-aligning vehicle wheels and for subsequently realigning the vehicle wheels after usage and for verifying such re-alignment. A pre-alignment insert (150) is provided for singularly pre-setting the pivot axis of the upper control arm (34) by setting the position of a pivot axis bolt (92) in an elongatged slot (136). The insert (152) is installed on the bolt between an eccentric cam (94) and the sideface (140) of a bracket (130) rigidly connected to the frame (30) and prevents lateral movement of the bolt (92) to limit the bolt to a singular pre-set position. A nut (64) is tightened on the bolt and holds the cam (94) against the insert (150) and to hold the insert (150) against the sideface (140) to in turn hold the cam (94) in a pre-set position in the guide channel (142) on the sideface of the bracket to hold the bolt (.rho.) in a pre-set condition, to provide factory prealignment. The insert also prevents a canted cam condition, to provide a tightly fastened assembly, to prevent premature loss of alignment. After vehicle usage, the nut (64) is loosened, the insert (150) is removed, the bolt (92) is laterally moved in the slot to a desired reset position to previde re-alignment, and the nut is re-tightened to hold the cam (94) against the sideface (140) of the bracket (130), without the insert (150) interposed therebetween. The insert (150) is forwarded to the vechicle manufacturer for verifying re-alignment.
