Just wondering if anyone knows a part number for the transfer case rear output bearing and seal. I found a bearing on rockauto but I think it's for a different transfer case than the one I have. I would like to order them before I pull it apart. Any help is greatly appreciated

 

Some help as to whether you have a manual or automatic tranny would be helpful

 

My bad, it's a 4 speed manual with 4x4

 

For RF1-A case>> Rear output bearing is Toyota 90363-28004 which is SKF 63/28J

The seal numbers are>> 90311-38140 which is SKF 14730

>> 90312-48001 which is SKF 18962

Once the SKF numbers are known, it is possible to cross reference these bearing and seal numbers to those of just about any other maker.

One of these seals is the final output seal and the other one is the oil pump seal that is found inside the output tail case

I don't remember which is which, but an examination of the seal number dimensions would tell

Here are the SKF Master lists>> SKF_bearing_master_interchange_2009.pdf

Thank you that's perfect!

 

Can this bearing be changed with the transfer case still in place or is it easier to do it on the bench?

 

It can be changed with the case still installed.
You should consult the factory service manual before disassembly because there is a small ball that retains the speedo gear that can be lost into the deeper case.

Often times though, the larger front bearing on the output shaft line might found to be worn when the output side has suffered and needs changing.
Both that front bearing and the rear output bearing are turning any time the truck is operated, both in 2WD and 4WD.
In order to change the front bearing, the case must be removed from the tranny in order to disassemble it that far.

 

Okay I'll maybe just pull the transfer case to check the other bearing for peace of mind. The manual I downloaded says to remove the transmission as part of removing the transfer case. Is that really necessary or can I remove transfer with transmission still in place?

 

The transfer case can be removed, leaving the tranny in place, but support will be needed under the tranny, as the crossmember that supports both of them has to be removed.

 

Right on, thanks for the info!

 

If you’re looking for the transfer case rear output bearing and seal, the best approach is to identify your exact transfer case model — the part numbers vary depending on whether it’s an NP231, NP241, or another variant. The rear output bearing is typically a high-load tapered roller or ceramic ball bearing, often matched with a specific output shaft seal, so using the correct model number or casting code from the case ensures a proper fit. While RockAuto lists several options, it’s common for listings to mix variants, so cross-check dimensions or use your vehicle’s VIN at a dealer or parts supplier to confirm the right BM500015 bearing and seal set before disassembly.
