The best way to straighten out frame rails?
 

Like most of these trucks, mine has had a few collisions here and there... the ends of the frame rails have taken some abuse over the years and the bumper brackets don't up all the way.... sledge hammer?

The best way is to take it to a frame shop but most around here charge $90 per hour.

A torch and hammer will work. Having a great big tree or telephone pull close will help. Its awfully hard to get them correct without a machine
