		Permissible difference in caster between right and left sides of the vehicle	*BE40.20-P-1001-20A
		Caster	*BE40.20-P-1002-20A
2	Check vehicle level again at the front axle after the camber adjustment and caster adjustment	 The vehicle level must match the values determined during the initial measurement.	AR40.20-P-0301R
