Vehicle alignment gauge fixture

A gauge fixture includes a chassis and a plurality of wheels mounted to the chassis. For each wheel, the gauge fixture includes a steering knuckle mounted to the wheel and a first member, a first end of the first member being mounted to the steering knuckle. The gauge fixture further includes, for each wheel, an adjustment stage mounted to the chassis, a second end of the first member being mounted to the adjustment stage, the adjustment stage configured to adjust a position of the second end of the first member relative to the chassis to change alignment of each wheel included in the plurality of wheels relative to the chassis, the adjustment stage including an indicator indicating a position of the second end of the first member relative to the chassis. Values from indicators and measured values from alignment sensors are used to calibrate the alignment sensors.
