for almost a year i've been convinced there was either debris in the hvac blower motor, or a hamster was running on a wheel somewhere in or under the car... it drives me crazy!!! this is the exact noise my 99 540i/6 makes from around 25mph and up - i'll stop looking for the elusive hamster wheel, and go ahead and replace the center support bearing ;-) thanks for posting this!!
