Method for wheel alignment

A method of correcting for misalignment of caster and camber on the wheels of an automotive vehicle comprising:

• placing said vehicle on an alignment rack,
• ascertaining the extent of initial misalignment of both caster and camber in the vehicle wheels,
• removing said vehicle from said alignment rack,
• elevating said vehicle frame to remove the vehicle weight from said vehicle wheels,
• screwing onto a wheel spindle a fitting having annular internally threaded means for coupling to a wheel spindle, a first degree gauge mounted on said fitting and adjustable for horizontal orientation parallel to a wheel spindle, a second degree gauge mounted on an annular ring disposed upon said fitting in rotatable fashion relative thereto and adjustable for horizontal orientation in a plane perpendicular to said spindle,
• rotation said annular ring relative to said fitting to bring said second degree gauge into a horizontal orientation,
• securing said annular ring to said fitting to prevent further relative rotation between said ring and said fitting,
• calculating the desired adjustments to caster and camber to correct for any misalignments in caster and camber,
• installing an eccentric on a ball joint which carries said spindle,
• tightening said eccentric until preloading is reached, and
• tightening said eccentric further while concurrently observing camber and caster on said first and second degree gauges, respectively, until camber and caster are at an optimum with respect to said desired adjustments.
