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.

A wheel alignment and measuring apparatus comprising a fixture for precisely mounting onto a wheel having an axis of rotation and defining a rolling plane perpendicular to the axis, an annular surface of the wheel which is spaced from and faces inwardly toward the axis, and a shoulder surface on the wheel substantially parallel to the rolling plane of the wheel joining said annular surface, said shoulder surface being spaced inwardly from an outermost rim edge, said fixture comprising first and second scaler assemblies, each of said scaler assemblies including a scaler bar having a longitudinal axis, and a head member, each of said head members having a mounting surface that is perpendicular to the longitudinal axis of the scaler bar and adapted to engage the shoulder surface of a wheel for precisely positioning the scaler bars perpendicular to the rolling plane of the wheel; means on each head member engaging said annular inwardly facing surface at two separated locations for centering said head members along a diametral line relative to the axis of the wheel; means to create a force tending to separate said head members to securely lock the head member onto the wheel with the scaler bars thereby positioned at a known location with respect to the wheel; means on the scaler bars to provide a distance measurement from the plane defined by the shoulder surface and against which the head members seat in direction parallel to the wheel axis; and angle indicating means on at least one of the scaler bars of one fixture for holding a provided reference line extending to another fixture on a wheel on the same side of a vehicle on which the fixtures are mounted, said angle indicating means having indicia forming radial lines from a center and the reference line being attached at the one scaler bar at such center, the radial lines being calibrated for directly indicating the angle of steer of a wheel on which the first mentioned fixture is mounted by orienting such radial lines relative to the mounting surfaces of the head member of the one scaler bar having such angle indicating means.
