Proper measuring procedures produce accurate repairs and make quality wheel alignment possible. Frame measurement manuals teach two completely different methods. It is necessary that you understand both methods. 1.)Grid Method: Frame manual horizontal side view length dimensions apply only to grid type measuring equipment which measures straight line distances in the square-box sections of a grid. A study of any vehicles' frame or Uni-Body control hole locations, proves that seldom are any two holes in exact square alignment with each other. 2.) Tri-Angulation Method: Bottom view frame manual measurements teach the exact angular distance from Point-to-Point between control holes and work on the principal of tri-angulation. This DVD will make measuring a simple and valuable tool that you can rely on.
