Abstract
A device for measuring and determining the condition of wheel position and alignment in a unibody automobile, include wheel setback, toe-in, toe-out, front end squareness, camber, caster, wheel base, tram, and tracking in a simple single configuration tool. The basic instrument is a fixture that installs on each wheel within the perimeter of the wheel, and includes angle measuring and distance measuring arms that interplay geometrically to diagnose each required wheel/body condition. Simple mechanical rulers and levers are all that is necessary for use.
