ABSTRACT:
An apparatus and method for determining the proper position of misaligned vehicle parts utilizes an X, Y and Z coordinate system to provide a proper point of position, or alignment, of vehicle parts which are identified in tables by such coordinates. The apparatus includes a framework which is established about the vehicle by transverse bars, datum plane bars, cross bars and a vertical standard, all with scale indicia, and forming a point of origin as on a graph. Lasers emitting planes of visible light are mounted on the datum plane bars and cross bar and project mutually perpendicular, intersecting planes of light. A laser is also mounted on the standard to project a horizontal plane of light that intersects the other two light planes and establishes a point capable of definition by X, Y and Z coordinates. The lasers are adjusted on the bars and standard to the measurements set forth in the table of coordinates and the error noted between the intersection point established by the X, Y and Z coordinates and the actual position of the misaligned part. Bending forces are applied to the frame area, or removal and replacement of parts is accomplished to correct the mispositioning or misalignment.
