Front wheel bearings: 4x4 (Dana 44 TTB)
4x4 F-150s of this era use the Dana 44 Twin Traction Beam front axle. Each front hub has a serviceable inner and outer tapered bearing, each with its own race, plus a hub seal. The easiest buy is a complete kit with both bearings, both races and the seal for each side.

Before you order
- Some 1987–1989 trucks came with 'pancake' hubs that do NOT take these bearings. Check the old bearing's part number if you're unsure.
