Ok, I have been listening to this sound for a couple a hundred miles and am stumped.

Best described as a roaring sound coming from the back, but does not occur at all speeds or driving conditions. Specifically, only when in either 4th and 5th and only at lower rpms (say between 2800 and 3200).

Additionally, I only hear it when holding at a constant speed. I.E. if I accelerate through that rpm range - no roar. Only occurs if I let off power, then re-apply power but only to maintain a constant speed. Consequently it only seems to occur while "cruising" in 4th and 5th (at the stated rpm range).

My first fear was tranny bearings, but wouldn't I hear it at all speeds?

CV joints?

please help, so far my only solution is to either downsift or turn on the radio (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)
