Abstract
A light projector mounted on a front wheel of a vehicle provides a pair of light beams. The first light beam is projected to a roof mirror mounted on an adjacent rear wheel and is reflected to a first target mounted with the projector on the front wheel of the vehicle. The toe angle of the front wheel relative to the axis of rotation of the rear wheel of said vehicle is calculated from signals which are developed by said first target. The second light beam is projected to a mirror mounted on the other front wheel and is reflected to a second target mounted adjacent to the projector to determine the total toe angle between the front wheels. The difference between the total toe angle and the measured individual toe angle of the front wheel upon which the projector is mounted is calculated to provide the individual toe angle of the other front wheel relative to said axis of rotation of the rear wheel of the vehicle.
