The short version
- The Bronco wheel bearing chart splits by locking hub type, the only vehicle on this site sorted that way.
- Auto-locking hubs, 1990 to 1994, and all 1995 to 1996 trucks use SET37 inner, SET45 outer, seal 4250.
- Manual-locking hubs, 1990 to 1994 only, use SET38 inner, SET45 outer, seal 710091.
- The rear Sterling 8.8 axle uses seal 8835S and bearing-and-seal kit TRP1559TV.
A previous owner may have swapped the locking hubs on this truck long before it reached its current driveway. That swap changes which Bronco wheel bearing set fits, since the split here runs by hardware type, not model year. Every other chart on this site sorts by date or VIN, not by which hub is bolted on.
The split that actually matters
SET37 is the front inner bearing for auto-locking hubs, used from 1990 through 1994, and for every 1995 and 1996 truck regardless of hub type. SET38 is the inner bearing for manual-locking hubs, but only on 1990 through 1994 trucks.
Both share the same outer bearing, SET45. The seal differs: 4250 for auto-locking hubs, 710091 for manual-locking hubs.

Check the hubs before ordering. A 1990 through 1994 Bronco can wear either auto-locking or manual-locking hubs, and a previous owner may have swapped one for the other.
Ordering a Bronco wheel bearing set by year alone will not settle it for those model years. Look at the physical hub hardware first, then match the set above.
Not the same truck as the new Bronco
Ford revived the Bronco name starting in 2021 on an unrelated platform. That truck runs its own listings, matched by VIN, and nothing on this chart carries over. Shoppers cross-referencing the modern Raptor or F-150 should treat the 1990 to 1996 Bronco as a separate parts family entirely.
Serviceable bearings, front and rear
Every bearing on this truck is a serviceable tapered design, front and rear alike. That means repacking and adjustment are routine maintenance, not a last resort. Trucks in the wider Ford lineup from this era mostly share that same service pattern.
Diagnosing a Bronco wheel bearing
- Identify the hub type first. Look at the wheel center caps to confirm auto-locking or manual-locking hubs before ordering anything.
- Listen for a load-linked growl. A worn Bronco wheel bearing often gets louder off-road or under a heavy load.
- Check for play at the wheel. With the truck raised, grip the tire at 12 and 6 o’clock and rock it firmly.
- Inspect the grease and seal. Dry, gritty, or discolored grease during a repack points to a seal that failed early.
- Confirm with a bearing check. A full walkthrough is available on the bearing check page before any part gets ordered.
Common questions
How do I tell if my Bronco has auto-locking or manual-locking hubs?
Auto-locking hubs engage automatically with four-wheel drive and have no dial on the wheel. Manual-locking hubs have a visible dial that a driver turns by hand.
Do 1995 and 1996 Broncos ever use manual-locking hubs?
No. Every 1995 and 1996 truck uses the SET37 and SET45 auto-locking hub set with seal 4250.
Does the new Bronco share any parts with this one?
No. The 2021 and later Bronco is its own listings, matched by VIN.
What does the rear axle need for this truck?
The Sterling 8.8 rear axle uses seal 8835S and bearing-and-seal kit TRP1559TV across the full 1990 to 1996 run.
Can a previous owner change which hub set my truck needs?
Yes. Swapped hub hardware changes the correct Bronco wheel bearing set, so check the physical hubs before ordering.
