This is a video on how to rebuild your BMW X3 Transfer Case (ATC-400) I got my bearings for here: https://www.americanpowertrainwarehouse.com/bmw-x3-w-tod-atc-400-transfer-case-chain-fits-03-borg-warner-hv-086-made-in-usa/
and the Bearing Kit here: https://cobratransmission.com/bmw-x3-bearing-kit-55133001-1
UPDATE: Before you take the transfer case apart, use a cardboard drawing of the case and when you extract each bolt, stick it through the cardboard. This will guarantee that when put it back together you will put the bolts in the correct location. (You can see my cardboard cut out at 5:35 in the video)
