Setback applies to both the front and the rear wheels. Setback is the amount that one wheel spindle may be aligned behind the other wheel spindle. Setback may be the result of a road hazard (heavily hit pothole, for example) or a collision. The first clue is a caster difference from side-to-side of more than one degree.
