To get an accurate measurement it is best to jack up one front tire on level ground and then put a piece of chalk in some kind of holder and scribe a line by spinning the tire. Do that on the other side. Then measure up to mid height on the front and back side of the tires. Mark those spots with a thumbtack or a push pin. Lower the vehicle and roll it back and forth a couple times to take out the squirm. Make sure you are back in the original position, equal height front and back, and then measure between the two points in front and in back. The front ought to be about 1/8 shorter than the back. I can tell you how to measure camber and caster if you want. But it is a little more complicated. Jim
