Do you happen to have part numbers or links to the bearings you ordered?

Xfer case is fine, it痴 leaking coolant from behind the motor, down through the bellhousing. Only three things it can be, and from what i can see so far, not the easy one (rear coolant manifold and/or hoses). That leaves the valley pipes and or pan, which will suck, but will be infinitely easier than the rear coolant cover that bolts down on the back of the block above the crank seal. It痴 under the bellhousing, so that痴 cool.
Intake is 50% off this am and I知 hoping to see coolant from the pipes or valley. 10k on a new motor and it痴 already leaking. I値l post some pics later, but the right vanos has a small weep that has made a bit of a mess on the front of the head. Nice work BMW.
Regrading bearings, the FAG taper bearings are no longer made, but Quaife, and others I contacted said FAG makes a ball replacement that will work. See email below from a UK company:

I didn稚 go too far down that rabbit hole as I found taper bearings at DiffsOnline. Ping Dan Fitzgerald at Dan@diffsonline and ask about the bearings he just shipped to New Orleans for an X5 4.4 diff. He痴 the owner I think and does a lot of bmw diff work it seems.
The bearings look identical, but are made in Japan. We値l see how they work. I had them pressed on yesterday by a local steering shop, so the diff is ready to assemble. As soon as I see where the coolant is coming from on my ungrateful x5.
