Body and Frame: Description and Operation

Frame and Underbody Description

The front suspension lower control arms are bolted to a suspension support. The front suspension support attaches to the underbody using four bolts. The engine bolts to the integral front side rails. Ensure that the suspension strut towers are dimensionally correct in relation to the remainder of the underbody. This will allow the vehicle to maintain correct caster and camber angles.

The individual underbody components contribute directly to the overall strength of the body. Ensure that you use the proper welding techniques. Properly seal and rustproof the underbody components under the following conditions:

-Whenever the body repair operations destroy or damage the original sealing

-Whenever the body repair operations destroy or damage the rustproofing

When rustproofing critical underbody components, use a good quality type of air dry primer such as corrosion resistant chromate, or an equivalent material. Do not use combination type primer surfacers.
