ABSTRACT:
An automobile body2with a wheel mount5vertically movably mounted thereon is supported, and the wheel mount5is lifted to an adjusting position which is set so as to be lower than the position that the wheel mount5takes when the automobile is running. The position of the wheel mount5as it is lifted and toe and camber angles thereof are measured, and estimated values of the toe and camber angles at the position that the wheel mount5takes when the automobile is running are calculated based on the measured values. Thereafter, adjustment quantities for the toe and camber angles at the adjusting position are calculated, and wheel alignment is adjusted at the adjusting position based on the adjustment quantities. Wheel alignment of the automobile can be measured and adjusted quickly and accurately for increased productivity without applying the same load to the automobile body as the load that is applied when the automobile is running.
