Frame & Unibody Repair

If the impact reached structure, the repair has to be measured. Panels can be judged by eye; rails, pillars and floor pans cannot.

Overview

Frame & Unibody Repair

Unibody vehicles do not have a separate frame — the body shell itself carries the load and manages crash energy through engineered crumple zones. When a collision deforms that shell, everything downstream is affected: how the doors close, how the suspension geometry sits, how the vehicle tracks at highway speed, and how it will behave in the next impact.

Straightening it correctly means comparing the vehicle against the manufacturer's published dimensions at dozens of control points, pulling it back within tolerance, and verifying the result with a second measurement — not eyeballing the panel gaps and calling it done.

What this service covers

  • Computerised three-dimensional measuring against factory data
  • Multi-point anchoring and controlled pulling
  • Rail, apron, pillar, rocker and floor pan sectioning
  • Structural panel replacement to manufacturer procedure
  • Corrosion protection and cavity wax on all repaired structure
  • Suspension component inspection and replacement
  • Four-wheel alignment and thrust-angle correction
  • Documented before-and-after measurement report

Signs of structural damage you can see from outside

Any one of these after a collision is worth having measured, even if the outer panels look acceptable and the vehicle drives.

Key points

  • Uneven gaps between doors, hood, fenders or trunk lid
  • A door that catches, drops, or needs to be lifted to latch
  • The vehicle pulling to one side or the steering wheel sitting off-centre
  • Uneven or unusually rapid tyre wear after an impact
  • Wrinkling or buckling in the floor pan, wheel arch or rocker area
  • A hood or trunk that no longer sits flush when closed

Modern materials change the procedure

Today's vehicles mix mild steel, high-strength steel, ultra-high-strength boron steel, aluminium and composites within the same shell, and the manufacturers publish specific instructions for each. Some components may be straightened; others must be replaced outright because heating or pulling them destroys the properties they were engineered for. Sectioning is permitted only at defined locations, with defined joint types.

We work to the published repair procedure for the vehicle in front of us. Treating a boron-steel pillar like ordinary sheet steel produces a vehicle that looks repaired and will not perform as designed in a second collision.

Corrosion protection after structural work

Alberta roads are salted, and every cut, weld and drilled hole made during a structural repair is a new place for corrosion to start. Cavity wax, seam sealer and corrosion-inhibiting primer applied to the correct areas are part of the repair, not an upsell — leaving them out is how a properly straightened vehicle rusts from the inside out three winters later.

Collision & Autobody FAQ

Questions about frame & unibody repair

If yours is not here, call the shop — somebody who works on the vehicles will answer it.

Can a vehicle with frame damage ever be safe again?

Yes — provided the repair follows the manufacturer's procedure, the structure is measured back within published tolerance, and the correct materials and joining methods are used. That is exactly what the measurement report is for: it is documented evidence rather than an assurance.

Will structural damage show on a vehicle history report?

A reported insurance claim may appear on services such as CARFAX. A repair completed and documented to manufacturer specification is a far stronger position at resale than an undocumented one — keep the paperwork we give you.

How do I know the measurements were actually done?

Ask for the report, and we will hand it to you. Every structural repair we complete includes before-and-after measurement documentation in the file.
