It is definately a mechanical sound. I have a 2001 and have noticed this for about a year now
I posted on our forum, but nobody else had experienced the same problem.
It only happens when I accelerate for a few seconds and then fades out. It is not the exhaust or anything loose in the engine bay. It is definately from the engine / Tranny area.
It almost sounds like the timing chain slapping etc...???
