Frame straightening is a crucial aspect of quality collision repair. Improper or imprecise frame alignment can compromise other aspects of the repair, and can potentially cause premature tire wear, poor fuel economy, suspension problems, alignment issues, uneven steering, not to mention safety issues. So frame damage isn't something to be taken lightly.
While many auto body shops might have the tools and expertise to perform reasonably good general collision repairs, accurate frame straightening requires expert attention and equipment. Returning your frame to factory specifications involves realigning the frame to tolerances of 3mm or less. This level of precision requires state-of-the-art computerized measurement technology in the hands of experienced technicians.
When a vehicle is involved in a collision, visible damage occurs to the panels and components within the area of impact. However, in many cases, damage can also occur to the unibody or inner frame.
