Driveshaft center mount bearing symptoms?

[pachieh]

I have a separate thread where I'm troubleshooting some weird random noises taking off from a stop: https://f15.bimmerpost.com/forums/sh....php?t=2067842

Thinking on my drive this evening (where it happened from a dead stop and medium throttle), could a bad center mount bearing on the main driveshaft cause the driveshaft to flex enough to where it would temporarily "bounce" off the aluminum heat shield between it and the exhaust?
