The two types of automobile construction are body on frame and unibody. Body on frame is mostly used for trucks and SUVs. Unibody is the construction used for most automobiles and smaller crossover SUVs. Some vehicles like Jeep Cherokees are a combination of these two designs. Regardless of the design, the frame of a vehicle has multiple functions. First it defines the dimension of the vehicle. The frame is what all other parts align with. Secondly, the frame is designed to provide safety in the event of a collision. It is built to bend and crumple in certain places in order to absorb the energy of a collision while at the same time protecting the passenger compartment.
In about half of collisions there is some degree of frame damage. It could just be the bumper mounting member that’s bent of the damage could be extensive enough to require the replacement of a part or all of a frame rail. Frame repair not only involves restoring frame components to their original dimensions, but also to their original strength. Where metal is bent it becomes hardened in the bend where the molecules are pushed together. Through a process called 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 our Korak frame rack which is a platform onto which the vehicle can be clamped. It also uses hydraulic rams which will pull with a force of up to 20,000 lbs. Along with the devices for pulling, our Shark electronic measuring system monitors the progress. 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 can then be aligned correctly. Our Shark measuring system provides printed before and after frame measurements to accompany your records. A four wheel alignment then follows all structural repairs.
