  • Appartus and method for adjusting vehicle toe alignment angles
    Patent number: 5553389
    Abstract: Toe of a pair of wheels on the same axle is adjusted by first measuring the toe of a first wheel of the axle. A specification value for the toe of the first wheel is then subtracted from the measured value of toe for that wheel, and the difference is stored as a first toe comparison value. The toe of a second wheel on that axle is adjusted until the total toe of the wheels on that axle minus a specification value for total toe for the wheels on that axle equals the first toe comparison value. The toe of the first wheel is subsequently adjusted until the total toe of the wheels on the axle is substantially equal to the specification value for the total toe for the wheels on that axle. Apparatus which performs the method is also disclosed.
