Abstract
An improved method, and apparatus for performing the method, is disclosed for measuring and correcting the individual toe of pairs of steerable and non-steerable wheels of a vehicle relative to a longitudinal centerline passing through the midpoints of the wheel pairs. The improved methods utilize aimable alignment heads which are alternately mounted on the non-steerable wheels and the steerable wheels and are sighted only once on targets on the other wheels thereby eliminating the need for resighting after each toe adjustment is made. Optical cross-toe paths of each head operate in a continuous mode and provide a running display of incremental toe angle adjustments of one wheel while the toe display value associated with the other wheel of the pair is frozen, which other wheel is not being adjusted for toe.
