Vehicle alignment gauge fixture

A method for alignment sensor testing, the method comprising:

• positioning a gauge fixture relative to one or more wheel alignment sensors, the gauge fixture including:
• a chassis;
• a plurality of wheels mounted to the chassis;
• and
• for each wheel of the plurality of wheels:
• a steering knuckle mounted to the each wheel;
• a first member, a first end of the first member being mounted to the steering knuckle;
• and
• 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;
• adjusting the position of the second end of the first member relative to the chassis for one or more wheels of the plurality of wheels;
• reading the indicator to obtain a measurement for each wheel of the one or more wheels;
• measuring the plurality of wheels using the one or more wheel alignment sensors to obtain measurements;
• and
• calibrating the one or more wheel alignment sensors according to the measurements.
