I have searched far and wide for 31212226640 hubs as specified in Real Oem.
Car is 91 M5 5/90 build. They don't seem to be for sale any where.

Anyone have a reliable cross reference for alternate part numbers that can be used?

TIA, Rob

Front bearing hub assy.

The part # you have (31 21 2 226 640) is correct and should be available to order from any BMW dealership. Nine are available at varios warehouse locations in US.
