The short version
- A 1994 Ford Explorer wheel bearing replacement means packing a tapered set, not swapping a hub.
- 2WD trucks use seal 6815 with inner SET6 and outer SET2.
- 4×4 trucks use seal 4250 with SET37 on both the inner and outer race.
- The rear is a solid axle. It is axle bearing work entirely, with no wheel position number documented.
Four model years of Ford Explorer trucks share one hardware story from front to back. This page covers 1991 through 1994, before the Explorer changed its bearing setup in 1995. A 1994 Ford Explorer wheel bearing replacement always means repacking or replacing a tapered set on the spindle.
Ford Explorer wheel bearing numbers by drive type

This page covers the 1991-1994 Ford Explorer: 1991, 1992, 1993, 1994. Other years live on the main Ford Explorer wheel bearing page.
Nothing on this Explorer is a hub assembly. Both ends of the front axle want repacking or a full rebuild with new cones.
The rear is axle bearing work entirely, with no wheel position number in the catalogs. A shop quoting a rear number for this truck is guessing, not reading a real listing.
Year by year
One hardware story covers all four years, 1991 through 1994. Nothing changes front or rear across this span.
A shop pulling a part for any single year in this range can use the same catalog page as any other. There is no mid cycle update to track here, unlike many later trucks.
1995 moves to a different setup on the next page entirely.
Before the bearing setup changed
This Explorer sits before the 1995-2001 Explorer, which uses its own bearing setup. Nothing from this page carries forward to that later truck.
A 1994 Ford Explorer wheel bearing replacement on this body has nothing in common with a 1996 truck two years later.
Drive type, not year, is the only real decision point across this four year span.
Diagnosing a Ford Explorer wheel bearing
- Rule out the tires first. Uneven wear or a separating belt can sound like a bad bearing. Compare against tire noise or wheel bearing symptoms.
- Check for play. Jack up the wheel and rock it at twelve and six. See how to check a wheel bearing for the full steps.
- Repack rather than replace. Both fronts use tapered cone and cup pairs. See repacking a wheel bearing before buying new cones.
- Set preload correctly. A tapered set that is too tight or too loose fails fast. See preload and end play for the adjustment.
- Confirm drive type first. 2WD and 4×4 use completely different cones. Check that before ordering any part.
Common questions
What wheel bearing does a 1994 Ford Explorer use?
A 1994 Ford Explorer wheel bearing replacement means SET6 inner and SET2 outer on 2WD trucks, with seal 6815. 4×4 trucks use SET37 for both races instead.
What wheel bearing does a 1991 Ford Explorer use?
A 1991 Explorer uses the exact same setup as 1994. Nothing changed across this four year span.
Is the front a bolt on hub on this Explorer?
No. Both 2WD and 4×4 fronts are serviceable tapered sets. They get packed and adjusted rather than replaced as a unit.
What is the rear wheel bearing on this Explorer?
The rear is a solid axle with no wheel position number documented. This is axle bearing territory, match the old part or run the VIN.
Does the setup change for 1995?
Yes. 1995 moves to a different bearing setup entirely. That generation is covered on its own sibling page.
