A4 driveshaft/bearing problem

["TM" <mizutanit@mindspring.com>]

Okay listers,
I asked if there are any listers w/ A4s and it appeared that not too
many people did. However, I have a problem that I can't figure out.

I'm getting a grating/rubbing/groaning sound from approx. the middle
of the car, only when decelerating or turning left and only when the
engine is warm. Can anyone give a suggestion as to why this may occur?
I had the car up on a lift Sunday and it appeared that nothing was really
amiss, although the heat shielding between the driveshaft and the exhaust
was slightly bent. That was bent back into place, although now I'm
wondering if it needs further bending and something is contacting the
driveshaft.

It sounds like something is rubbing, but it is very difficult to say
exactly what is going on, as I cannot take a look under the car while
it is running down the road and I can't really see any visible damage
or anything.

Any suggestions? This is driving me nuts.
