Jeep Structural Repair: Wrangler Body Tub and Grand Cherokee Unibody

Jeep structural repairs range from the Wrangler's body tub and windshield frame to the unibody Grand Cherokee. Here is how each is handled.

Two Very Different Structures

Jeep builds rugged body-on-frame vehicles like the Wrangler alongside unibody SUVs like the Grand Cherokee, Compass and Cherokee. Structural repair looks very different on each.

The Wrangler Body Tub

The Wrangler's body is a steel tub bolted to the frame. Current models use aluminum for the doors, hood, fenders, windshield frame and tailgate. Structural repairs to the tub, such as rocker or floor damage, are handled with steel repair methods, while attached aluminum parts need separate tools and corrosion isolation.

The Windshield Frame

The Wrangler's windshield frame is a key structural piece that also supports the roof. Damage from impacts or rollovers requires careful inspection, and replacement parts must be installed and sealed properly to prevent leaks.

Unibody Jeeps

On the Grand Cherokee and other unibody Jeeps, the body is the structure. Rails, pillars and floor pans are repaired or replaced according to Jeep's procedures, with specified welding and bonding methods and restored corrosion protection.

Rollover Damage

Jeeps can roll in off-road accidents. Roof, pillar and windshield frame damage should always be evaluated professionally, and sport bar or roll cage padding is inspected in Wranglers.

Frequently Asked Questions

Can a Wrangler body tub be replaced?

Yes. In severe cases, body tub replacement is an option.

Why does aluminum matter on a Wrangler?

It needs different tools and methods and must be isolated from steel to prevent corrosion.

Are Grand Cherokee repairs like other SUVs?

Yes. They follow unibody structural repair principles.
