Superduty 99-04 Unit Bearing Tool

The Super Duty 99-04 Unit Bearing Tool is a DIY weld-together fixture that lets you disassemble the front unit bearings on a 1999-2004 Ford Super Duty Dana 60 so you can swap the ABS tone rings. Instead of buying a costly one-off press setup, you weld the supplied laser-cut plates together using the etched guide lines and use it with an impact driver to separate the unit bearing.

Key Features

• Precision CNC laser cut from 3/16" and 1/4" mild steel, plus a 3/16" AR hardened plate for the impact-driver surface
• DIY weld-together kit keeps the cost low
• Laser-etched guide lines so you can weld the plates concentrically and true
• Purpose-built to disassemble 99-04 unit bearings for tone-ring changes
• Reusable shop tool for one-ton Super Duty axle builds

Fitment & Compatibility

Made for the front unit bearings on the 1999-2004 Ford Super Duty Dana 60 front axle. It is commonly used during a one-ton front axle swap when you need to change tone rings to match your ABS setup.

Frequently Asked Questions

What does this tool do?
It lets you take apart the 1999-2004 Super Duty front unit bearings so you can change the ABS tone rings, then reassemble them.

Do I have to weld it together?
Yes. It ships as a DIY weld-together kit; you weld the laser-cut plates together along the etched guide lines. That is what keeps the price down.

Why is there an AR hardened plate?
The 3/16" AR (abrasion-resistant) hardened plate stands up to being driven with an impact driver during disassembly.

Any cautions?
Take your time. Improper use of the tool can damage a unit bearing, so follow the process carefully and support the bearing correctly.
