ABSTRACT:
A system for monitoring the alignment of the wheels, such as the front wheels, that control the steering of a vehicle is provided. The system includes a pair of alignment sensing devices that extend between each steering arm and a tie rod coupled to the arm, of the vehicle's steering assembly. The sensing devices include a pair of concentric tubes retained in a slidable relationship and an alignment sensing system. After the wheels are aligned, the tubes are coupled to the steering assembly and are slid relative to each other, until the sensing system indicates that the tubes are aligned, thus indicating that the wheels are aligned. The sensing system is activated whenever desired by an operator of the vehicle. The sensing system provides a first signal to indicate that the front wheels are aligned and a second signal to indicate that at the front wheels are not aligned. Alignment is verified when the operator rotates a steering wheel of the vehicle in a desired direction until the front wheels are rotated fully in the direction. The sensing system is then activated. The operator then rotates the steering wheel in the other direction, until the front wheels are positioned fully in the remaining direction. During or after the front wheels are being positioned in the remaining direction, the sensing system provides either the first signal to indicate that the front wheels are aligned or the second signal to indicate that the front wheels are not aligned.
