200q Center bearing Repair

[TooManyAudis at aol.com]

I have the exhaust off my 200q20v for some repairs to the rear end (no 
schoolboy giggling, please), and was thinking that now would be a good time to pay 
the center driveshaft some much needed attention.

I have been getting noise when I let off the gas (like a metal on metal 
rattle) and I think it is narrowed down to the U-joint / center bearing area.  Of 
course, with this being a long hollow chunk of metal, it's difficult to say 
precisely from where the noise originates.

I did a google search and there is refererence to both a BMW and a Mercedes 
replacement bearing / carrier that will work with the audi drive shafts, but I 
am having trouble tracking down the exact part numbers and which bearing / 
carrier goes to which audi driveshaft.

If anyone has the information, please let me know, or, alternately, provide 
me with a link where it can be found.

Thanks,

Tom Werner
