The principle of checking the camber angle of the front wheel. The check is made on a level surface with the front wheels in straight position. The appropriate sizes must be set equally on both front wheels. It must be noted, that the adjustment of the correct alignment of the front wheels should in principle be carried out by a specialist at a service station for motor vehicles, which are equipped with special devices, allowing the measurement of all angles, including kingpin heel and lead angles. The characteristic angles of the front wheels are measured along a precisely horizontal section of a paved road, with the car fully loaded and the air pressure in the tires correct.
