Full Frame and Unibody


There are two types of automobile construction… Conventional full frame and unibody.

Frame repair involves restoring frame components to their original dimensions, as well as to their original strength. Where metal is bent it becomes hardened in the bend where the molecules are pushed together. During our “stress relief”, the molecules are arranged back to their original configuration and the steel is restored to its original strength.

This type of repair is done on a frame machine (platform where the vehicle can be clamped). It also uses hydraulic rams which will pull with huge force. Along with the devices for pulling, a measuring system is used. A common system uses a laser and reflective targets which are accurate to within one millimeter. This system can be used live and the dimensions of the vehicle can be monitored during the pull. The vehicle is measured in three dimensions; height, width and length. Once the frame has been restored to its original condition, all other parts will fit and the wheels will align correctly.
