RE: Wheel bearing search

Hi John.  If my info is correct at my end, that bearing number indicates
a bearing approximately 80 mm OD x 40 mm ID x 18 mm wide, open type
bearing, single row ball.  Is that right or is my cross reference wrong?
That seems to be about the right size and type of bearing to me, but I
haven't taken apart the hub on a quattro.  Let me know.
