Well, If you read my post below, you would see I may have to do this myself depending on the outcome with BMWNA and the dealer. I understand the hub assy. is a unit and has sealed bearings that press fit on the spindle. Where are instructions on how to replace them, and where can I find good cheaper replacements,(oxymoron!). I can get them through my dealer for 130 ea, but I seem to remember them for 90-100 somewhere. Thanks in Advance for any leads/advice. -Bob
