Frame Straightening
WARNING: This page is about a different car, the 2004 Dodge Dakota and 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
When necessary, a conventional frame that is bent or twisted can be straightened by application of heat. The temperature must not exceed 566°C (1050°F). The metal will have a dull red glow at the desired temperature. Excessive heat will decrease the strength of the metal and result in a weakened frame.
Welding the joints around riveted cross members and frame side rails is not recommended.
A straightening repair process should be limited to frame members that are not severely damaged. The replacement bolts, nuts and rivets that are used to join the frame members should conform to the same specifications as the original bolts, nuts and rivets.
