2021-2026 Ford Bronco & 2022-2026 Bronco Raptor Front Differential Reinforcement Bracket Kit - Driver Side

Ford's Technical Service Bulletin 25-2613 covers a loud clink or clunk from the front end that traces back to a cracked or broken front differential frame mount bracket. Ford ties the failure to the front differential flexing during extended driving in 4L. The dealer repair uses a Ford frame bracket repair kit and an AWD module software update.

• 2021-2024 Bronco, 2.3L or 2.7L, cracked mount, still under warranty — Go to your Ford dealer first and ask about TSB 25-2613.
• Bronco Raptor (any year) — The TSB lists 2.3L and 2.7L Broncos only, so this bracket kit is the way to reinforce the mount.
• 2025 or 2026 Bronco — Outside the TSB's 2021-2024 range. Reinforce the mount before it cracks.
• Out of warranty, or you want it done before it fails — This bracket kit is built for exactly that, and it can go on during a mount repair.

Why does the Bronco front differential mount crack?

Ford's TSB 25-2613 ties it to the front differential flexing during extended driving in 4L. The crack forms in the driver side frame bracket where the diff bushing bolts in.

How do I know if my front diff mount is cracked?

The usual first sign is a loud clink or clunk from the front end. The mount sits above the front differential behind the skid plates, so inspect the driver side bracket with a mirror and a light.

Does this kit bolt on?

No. It is a weld-in kit with no hardware in the box. The brackets weld to the frame and must be installed by a qualified fabricator or professional welder.

Can I install it before my factory mount cracks?

Yes. It's built to reinforce the factory mount before it cracks.

Is there a Ford TSB for this?

Yes. TSB 25-2613 covers 2021-2024 Broncos with the 2.3L and 2.7L engines. If your Bronco is out of warranty, a 2025 or 2026, a Bronco Raptor, or you want the mount reinforced before it cracks, this bracket kit is built for that.
