In modern automotive design, the structural frame and outer body panels are integrated into a single high-strength unit known as a unibody. Engineered with targeted crumple zones, ultra-high-strength steel (UHSS), and lightweight aluminum subframes, unibody structures are designed to absorb and deflect collision energy around the passenger cabin. Even a moderate collision can bend unibody frame rails out of alignment, compromising vehicle safety and wheel geometry.

The Autos of Chicago Certified Auto Body Shop, located at 1555 East Rand Road in Arlington Heights, IL, utilizes state-of-the-art computerized laser measuring benches to pull, realign, and restore damaged unibody chassis back to exact millimeter factory specifications.

Our Strategic 4-Stage Chassis Realignment Sequence

Stage 1: 3D Laser Structural Measuring & Mapping
We mount the vehicle onto our dedicated frame rack and use digital optical laser scanners to measure chassis reference points against original factory engineering blueprints.
Stage 2: Multi-Angle Hydraulic Vector Pulling
Using 10-ton hydraulic pulling towers, our collision specialists apply controlled multi-directional tension to reverse crash damage and pull unibody rails back to factory coordinates.
Stage 3: High-Strength Steel & Aluminum Structural Welding
Any crushed non-repairable crumple sections are cut out and replaced using factory-approved squeeze-type resistance spot welding (STRW) or pulse MIG aluminum welding.
Stage 4: Laser Suspension Alignment & ADAS Verification
Once the frame is aligned, we perform a 4-wheel laser alignment and calibrate safety radar sensors to ensure all driving assist systems operate correctly.
