I'm trying to figure out where I'm hearing this buzzing noise from. coming from under the car about in the middle. happens most at between 1500 and 2000 rpm in or out of gear and is louder under acceleration. below or above that range it's just a slight rattle and intermitent. It is worse when it's cold and sometimes gone competely once it's warmed up.

I hope these symptoms are detailed enough for someone to point me in the right direction. I was assuming something loose in the exhaust system but I've checked all of that and it seems fine. I thought maybe it was internal in the cat or muffler.

Recently on a Forester forum someone was mentioning their transmission being toast because of what they seemed to describe as a similar buzzing in the front diff. Is it possible that' where the sound is and how bad could that be? Any help would be great.
