The Mueller-Kueps Wheel Camber Adjuster, No. 514 300/2, allows a single technician to complete wheel alignments. Users place one end of the adjuster on the chassis and the other on the interior rim of the car. When the user releases the camber, the tool stops the wheel from pulling inwards and holds until the job is finished, according to the company. To achieve a more precise adjustment, users can span the camber tool.
