Had to make small adjustments.
Are you using wheel with the tires mounted? I prefer to use bare wheels to set camber and toe. It gives a more accurate reading then dealing with the flex of the tire. Also, be sure the vehicle is on a clean, flat, smooth surface. Cutting boards make for good inexpensive set up boards.
