Unibody repair uses some of the same tools as frame repair does. It is a little the same and a lot different. Unibody vehicles are made strong enough that the car or truck does not need a frame. There are a lot of high strength steels and crush zones in unibody vehicles. That means a lot more replacing so the car will crush the same if it is in a second crash. Crush zones are designed to crush and use up energy in a crash.
They should be replaced once damaged. We have an Auto Robot that was designed for repairing unibody vehicles. It has the ability to hold, measure, and pull a unibody back into shape. All this equipment is great. We add training, experience, and pride in workmanship. Now we’ve got a unibody repair system we can be proud of.
