Hi everyone!
I am rebuilding my front axle, and have split my axle and am replacing the bearings and races that marry the differential gear to the axles.
I wanted to post this since I have not seen this in any other posts.
The replacement bearings/races for this are:
Bower (original bearings)
BT-3920
BT-3984
I am replacing them with Timken
3984/3920 set
Just thought I would share if anyone else decides to go through this process.
Good luck!

Hope this helps. These are for the hubs not the carriers. I recommend you get the bearings from Kevin Lockwood. He usually has the best prices anywhere.

I looked up all the bearing numbers for the carrier. All these numbers come from the ORD 9, SNL G-102 parts book which everyone should have as an owner. Here are all the numbers. They are all Timken numbers.
Front axle
carrier side bearing 3984, cup (race) 3920
pinion inner 1305
pinion outer bearing 53176, cup 53375 (you will need two of each)

Thanks, Steve!
Copy all!
I noticed your earlier post, and just wanted to add the additional information for completeness.
Tracking on your sets of bearing numbers--all good!
Got my front axle rebuild set from Kevin, and am in the process of putting everything back together now. ;D
Cheers,
