Quick Measurement Method
Instead of using welding gauges for frame repair, the advancement of technology now prescribes the usage of straightening benches such as those made by Celette Co. or, Car Bench Co.
For quick evaluation of damage on the vehicle underbody, instructions are given in this group for the usage of an economical test method with the Telescope Measuring Instrument MKM-642-A. Its usage is quite simple. Exchangeable measuring points are used to quickly locate actual values at different measuring locations. Removal of components or trailer hitch (if present) is not necessary.
Checking the axle geometry gives further information on the extent of the damage. For measuring the front axle geometry see operation "Chassis Alignment" in group "E". For measuring the rear axle geometry see operation "Chassis Alignment" in group "F". Lifting of the outer spring winding from its seat is also an apparent sign of deformation of the outrigger or frame side member.
