Abstract

A portable laser emitter, laser target, and method for measuring the toe angle of a commercial truck steer axle are disclosed. The laser emitter is mounted to the wheel of a truck steer axle while the laser target is placed in front of the truck. Measurements are taken of the laser dot position on the target with the emitter mounted at either end of the steer axle. The process is then repeated with the target positioned behind the truck. The measurements taken from either end of the steer axle with both front and rear target positions are compared to determine the toe angle of the steer axle.
