Frame versus unibody
Trucks and some SUVs use a separate ladder frame with the body mounted on top. Most passenger cars and crossovers use a unibody, where the body shell itself is the structure. Both can be damaged without obvious outside signs, and both are repaired by measuring reference points and pulling or replacing sections to bring them back to manufacturer dimensions.
Signs that a car may have structural damage include doors or hood that do not align, uneven panel gaps, steering that pulls, tires wearing on one edge, and creases in the floor or trunk area. Even if you cannot see these, a hard hit warrants measurement.
How structural repair is done
The vehicle is secured on a frame machine so forces can be applied in controlled directions. Measurements are taken at defined points and compared against specifications. Pulls are applied in stages with re-measurement, rather than one dramatic yank, so metal is not overstressed.
Some structural parts are designed to be replaced, not repaired, and some high-strength materials cannot be heated or re-formed. Repair procedures published by vehicle manufacturers guide what can be done. Where a section must be replaced, it is joined using the specified methods.
After the pull: alignment, safety systems and verification
Once the structure is back within tolerance, suspension and steering components are inspected and a wheel alignment follows. Because structural work disturbs mounting points for cameras and sensors, driver-assistance calibration may be needed afterward, and we cover that under our ADAS calibration service.
We keep you informed on what the measurements show. If a vehicle has damage beyond sensible repair, an insurer may consider it a total loss, and we will walk you through your options.
Why measurement matters more than appearance
A car can look straight and be a few millimeters out in places that change how it tracks. Millimeters at a suspension mounting point translate to degrees at the wheel. That is why we trust measurement, not eyesight, and why a repair that is only judged by gaps can miss real problems.
Documented before and after measurements also give you and your insurer clear evidence of what was done. If you ever sell the vehicle, that record is worth having.
Ask us for the measurement printout if you would like a copy for your records.
Keep alignment symptoms in context
Pulling, an off-center steering wheel or a new vibration can have several causes after a collision. A wheel alignment alone does not establish that the structure is undamaged. Describe the impact direction, whether a wheel struck a curb and any change in door or hatch fit. Do not drive simply to demonstrate a symptom if the vehicle feels unstable. Structural questions are best resolved through inspection and vehicle-specific measurements rather than photographs or a visual comparison of the wheels.
What to gather before your visit
- Describe where and how fast the impact occurred
- Note any steering pull or vibration since the crash
- Check whether doors, hood and trunk close evenly
- Tell us about airbag deployment
- Bring claim details if the insurer has assigned an adjuster
