1.8.1 Toe-In Adjustment
Toe-in is a condition in which the front of the tires are closer together than
the back. This is used to compensate for the natural tendency of road-to-tire

steering linkage wear would allow the wheels to actually toe-out. By setting a
certain amount of toe-in, the wheels will be nearly parallel in actual use.
should be checked using a toe gauge or trammel.
1. Jack up each front wheel and chalk a band near center of tire while
spinning the wheel.
2. Use a sharp-nosed scriber to form a thin line near the center of the chalk
band while spinning the wheel. Keep the line THIN.
