I've been doing research the last few days gathering parts in the midst of my 3.91 install. Came across all the GM part numbers for bearings and seals and figured I'd share. The bearings all come with races. They're not hard to find with google. Anyhoo.....

Inner Pinion Bearing (big one inside the diff closest to the head on the pinion) - 20993936

Outer Pinion Bearing (smaller one next to the pinion seal) - 92243120

Crush Sleeve - 14012691

Carrier bearings - 92230402

Axle seals - 92230580

Pinion Seal - 92230584

All that being said, cheapest place to get them all in one package (that weren't possibly junk bearings) I found was from Lingenfelter (of all places) in a Master Kit from American Axle (maker of the Camaro OE diffs and gears) for $95. Buying it all separately from a dealer will run you probably north of $225-$250.

The AAM Master Bearing kit part number is 74060018. Comes with (2) Carrier bearings, (1) Inner Pinion, (1) Outer Pinon, and (1) Pinion Seal.

Rockauto has the best prices on axle seals and crush sleeves. I didn't need a crush sleeve as one came with the install kit I purchased but I figured to pick up and extra in case I over-torque one. Shipping prices blow but Amazon doesn't have jack in stock right now.

There's my f**k you Friday post because I care. A lot of people on here won't even change their own oil but for those of you wanting to wrench on your ride or save a buck or two (because those shits are valuable), here you go.
