Frame & Unibody

Frame & Unibody Straightening in Brooklyn.

Frontline Automotive straightens bent frames and unibodies in Brooklyn on a computer-measured frame bench, back to factory tolerance. Computer-measured structural repair for bent frames, deformed unibodies and post-collision alignment problems. If your car pulls, wanders or no longer closes square, the structure — not the wheels — is usually the reason.

Straight Structure Is A Safety Feature.

Your vehicle's structure is engineered to absorb a crash in a specific sequence. Once a rail, apron or floor section is pushed out of position, that sequence changes — and so does how the car handles, tracks and protects you next time. Cosmetic repairs over unmeasured structural damage hide the problem instead of fixing it.

At Frontline Automotive we mount the vehicle on a measured frame bench and compare it to factory dimension data point by point. Pulls are made in controlled increments, sections are repaired or replaced only where the manufacturer allows it, and welds follow specified procedures for the steel or aluminum in question. After the structure reads correct, suspension geometry and wheel alignment are set and verified.

The result is a car that tracks straight, wears its tires evenly, closes its doors and trunk cleanly, holds even panel gaps, and behaves predictably. That is the standard we hold on every structural repair that comes through 1903 Broadway.

Structural Capabilities.

Computer Measuring

Vehicles are measured against factory dimension data before, during and after the pull — no eyeballing, no guessing, and a printed record at the end.

Multi-Point Pulling

Frame bench and tower setups apply controlled pulls in the correct sequence and direction, restoring rails, aprons and mounting points to spec.

Sectioning & Welding

Panel and rail sectioning where the manufacturer permits it, with welds matched to the substrate — high-strength steel, boron or aluminum.

Alignment Correction

Suspension mounting points, thrust line, camber, caster and toe are all verified after structural work so the car actually drives straight.

Hidden Damage Discovery

Disassembly reveals what a walk-around estimate cannot. Everything found is photographed, measured and submitted as a supplement.

Documented Repair

You receive the measurement records and repair documentation — proof the structure was returned to factory tolerance.

Structural Repair Process.

  1. 01

    Intake & Towing

    Not drivable? We tow it in. Structural damage should not be driven on any longer than necessary.

  2. 02

    Disassembly

    Panels, bumpers and trim come off so the actual structure is visible and measurable.

  3. 03

    Measurement

    The vehicle is set on the bench and measured against factory data to identify every point out of tolerance.

  4. 04

    Controlled Pulling

    Pulls are made in sequence with continuous re-measurement until the structure reads within specification.

  5. 05

    Welding & Corrosion Protection

    Sectioning and welds to OEM procedure, then seam sealer, cavity wax and corrosion protection restored.

  6. 06

    Alignment, Calibration & QC

    Wheel alignment, sensor calibration where fitted, road test, and a final measurement record before delivery.

Common Questions.

How do I know if my frame is bent?
The common signs are a car that pulls to one side, uneven tire wear, doors or the trunk that no longer close cleanly, uneven panel gaps, and a steering wheel that is no longer centered when driving straight. A measuring session on the bench is the only way to confirm it — we measure against factory data rather than guessing by eye.
Can a bent frame be repaired safely?
Many can. Modern unibody structures are designed to crush in specific zones, and sections can be pulled back to factory dimensions or sectioned and replaced where the manufacturer permits it. Some damage is beyond safe repair, and in that case we document it so your insurer can evaluate a total loss honestly.
What is the difference between frame and unibody damage?
Trucks and some SUVs use a separate ladder frame under the body. Most modern cars and crossovers are unibody, where the structure and body are one welded assembly. Unibody repair requires measured pulling and manufacturer-specified sectioning rather than simply straightening rails.
Why does my car still pull after another shop repaired it?
Usually because the structure was never measured — only the wheels were aligned. If the thrust line or a suspension mounting point is off, alignment will not hold. We measure the structure first, correct it, then align.
Does structural repair affect resale value?
Structural damage is reported regardless of who repairs it. What you control is whether the repair was measured, documented and done to factory specification — that documentation is what protects the value you have left.
Do you handle the insurance side of structural claims?
Yes. Structural claims involve supplements for damage that only appears after disassembly. We photograph, measure and document each finding and submit it so the repair is not cut short.
