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)
