Call Beyer Driveline in AZ. You'll need to find a retailer willing to sell their stuff to you (we do) as they only do wholesale (but Beyer Motorworks, their BMW service front, might sell them). Replaceable joints, top quality, expedient, in my book the best you can get for a BMW.

Cool deal, have any idea what these units cost?
