[urq] Drive shaft center support bearing

[Buchholz, Steven]

I posted something to the main quattro list many years ago on my experience ... can't seem to find it from an archive search ... or in the KB.  When I rebuilt the propshaft on my car I found that the carrier bearing was pressed into the bushing, so I went out to a bearing shop with the standard sealed roller bearing ... they looked up the number and gave me a direct replacement.  Memory's more than a bit fuzzy, but ISTR something like 6006RSR for a P/N.  

In my search I did find a couple references for the urq ... I'll regurgitate them here:
