Toe Pattern Adjustment

After a toe pattern arc has been plotted, and is outside of allotted area on toe pattern graph, steering gear, rear toe links or both must be adjusted. If front toe pattern requires adjustment, steering gear can be raised using split shims. If steering gear must be lowered, gear mountings are misaligned and will require alignment.

If rear toe pattern requires adjustment, rear toe links can be raised or lowered using toe link shims. The rear toe links are mounted to frame in vertical elongated holes that allow toe link to be moved up or down. Toe link shims in increments of .079" (2 mm) above or below design (nominal) are used to position toe link. A .079" (2 mm) change in steering gear or toe link height will effect toe pattern by about .15 degrees when measured from design height (nominal) to either jounce or rebound positions. It is typical for a shim to have about .039" (1.0 mm) up and down play.
