[quote=”Ben” post=21830]I worked for Chrysler for a short while.
I don’t have the info in front of me, but I seem to recall that certain parts of the frame can be worked, others not. Cold is the best way, if possible. The centre section and hydroformed crossmembers shouldn’t be touched much, if at all. The front and rear sections can be worked a bit. If you heat it, you are supposed to use a heat crayon (800 degreee IIRC) and not heat the frame for more than a total of 3 minutes. Heating multiple times is not acceptable.
It can compromise the integrity of the frame by changing the characteristics of the metal. The front are rear are intended to be weaker than the centre (like a crush zone on a uni-body). And the centre is designed to be more rigid. I am sure you understand the dynamics of heating and cooling metal[/quote]
This is really what I wanted to hear. It’s something I felt I knew anyways but it’s nice to have confirmation. The job I am speaking of had a front frame horn down only 3 inches, without severe buckling and I’m sure I could have done it cold. Thanks for the awesome info!
:clappy No actually I work at a body shop and my boss was afraid to straighten this frame which is something I could have done in about an hour. The end result is me losing a weeks pay while he wonders what to do. It probably would have worked cold but I suggested heat and he panicked. All I would have had to do is tie it down behind the suspension and jack it up 3 inches, not rocket science.
LOL @ your insurance adjuster accusation!
