Home › Vehicles › Toyota › Toyota T100 Wheel Bearing Part Numbers
The short version
- The T100 wheel bearing setup is serviceable tapered hardware at every corner, not a bolt-on hub.
- 2WD fronts run 1993 to 1998: seal 1948, inner cone and cup M38549H-M38510, outer cone and cup 1380H-1328X.
- 4WD fronts are documented 1993 to 1997: seal 710092, inner cone and cup JLM104948-JLM104910, outer seal 710266, outer set SET47.
- A 1998 4WD front has no clean row in the catalogs; match the old part or confirm the VIN.
Toyota built the T100 as a full-size truck with mid-size roots. The front end shows it: hand-serviceable tapered bearings, the same approach Toyota used on the Tacoma it stood beside on the lot.
Two drivetrains, two number sets
Every T100 wheel bearing at the front is a tapered roller design: a seal plus an inner and outer cone-and-cup set.
2WD and 4WD trucks use entirely different parts, so the drivetrain has to be confirmed before ordering.
Repack and adjustment on this style of front end are covered on the repacking page and the preload page.

The 1998 4WD gap
The catalogs carry the 2WD front all the way to 1998. The 4WD row is only documented through 1997.
A 1998 4WD T100 has no clean listing behind it. Match the old part on the truck or confirm the VIN.
A serviceable front, not a hub unit
Nothing on the T100 front end is a sealed cartridge you unbolt and swap. Every listing here is a seal plus loose cone-and-cup sets. They are meant to be cleaned, inspected and repacked first.
Replace parts only when the rollers or races are actually worn or pitted. That holds for 2WD and 4WD alike.
The truck between the Tacoma and Tundra
The T100 was Toyota’s first full-size pickup, sized between the compact Tacoma and its eventual successor, the Tundra. The T100 wheel bearing hardware did not carry forward to either truck.
Both the Tacoma and the Tundra use their own separate listings.
Diagnosing a T100 wheel bearing
- Confirm 2WD or 4WD before pulling any part numbers.
- Pull the hub and inspect the grease rather than assuming a bearing is shot.
- Check races and rollers for pitting, not just for play.
- Set preload correctly on reassembly; a tapered set that is too tight runs hot.
- On a 1998 4WD or any rear job, work by VIN since there is no clean row.
The general check routine is on the checking page.
Common questions
Is the T100 wheel bearing a bolt-on hub?
No. It is serviceable tapered hardware, a seal plus cone-and-cup sets, meant to be repacked and adjusted.
Do 2WD and 4WD trucks share parts?
No. The two drivetrains use entirely different seals and cone-and-cup sets at the front.
What fits a 1998 4WD T100?
The catalogs stop documenting the 4WD front at 1997. Match the old part or confirm the VIN for a 1998 truck.
What about the rear?
There is no clean rear row in the catalogs for this truck. Match the old part or confirm the VIN.
Did the Tacoma or Tundra inherit these numbers?
No. The T100 sat between the two in size, but its front hardware stands on its own.
