[s-cars] Center Support Bearing?

[Stefan Richter]

Yesterday, my new to me 95 S6 Avant began making a slight metallic
knocking sound somewhere from the middle of the car, when accelerating
in 1st gear. The knocking was faster than the turning of the wheels. In
second gear, about 3-4K RPM, the knocking turned to a chirping sound. -
No Laughing please.  Today, knocking, chirping, and vibration in first
gear and second gear up to about 3500RPM.  No vibration at medium and
high speeds.  From my lurking on the list, I am thinking center support
bearing, or maybe driveshaft CV joints.  I got under the car and was
able lift the driveshaft near the center support bearing at least 1/2 an
inch upward and sideways with a long screwdriver.  The rubber busing
looked brittle but I cannot tell if it is torn.  Does this sound
familiar to anyone?  I vaguely remember something about a BmVee Part No.
Any help is appreciated on this rainy miserable spring day.

TIA
