Trammel Bar Gauge
A trammel bar gauge is a purely mechanical way to
check toe. It is used to measure the distance between the
center of the two front tires. First a distance measure-
ment is taken at the rear of the tires (centerline to cen-
terline), then the same measurement is taken at the front
of the tires. The difference in the measurements is the
amount of toe. Compare this reading with specifications.
