Front wheel bearings: 2WD (Twin I-Beam)
2WD F-150s from this era use two serviceable tapered roller bearings in each front rotor/hub, an inner and an outer, each with its own race. Replace them in matched sets (bearing + race) and put in a new inner grease seal whenever the hub comes off.

Specs
- Bearings per side
- 2 (inner + outer)
- Hub style
- Serviceable rotor/hub, tapered roller bearings
- Typical Ford adjustment
- Seat the nut at 17–25 ft-lb while turning the rotor, back off ½ turn, then snug to 10–15 in-lb (inch-pounds). Install the retainer and a new cotter pin.
How the job goes
- Loosen the lug nuts, jack the truck up, support it on a jack stand, and pull the wheel.
- Remove the brake caliper and hang it with wire. Don't let it hang by the hose.
- Pop off the grease cap, then remove the cotter pin, nut retainer, adjusting nut, and washer.
- Wiggle the rotor to drop the outer bearing out, then slide the rotor off the spindle.
- Pry out the inner grease seal and remove the inner bearing.
- Drive out both old races and drive the new ones in until they seat fully. Don't mix old races with new bearings.
- Pack both new bearings with grease, install the inner bearing, and tap in a new seal.
- Reinstall the rotor, outer bearing, washer and nut, then adjust per the spec above and install a new cotter pin.
Before you order
- Confirm the exact procedure and torque in a service manual (Haynes, Chilton, or a Ford shop manual) for your truck.
- Bearings and races are a matched pair. Replace them together.
