post up a video. mine was doing the same thing even in neutral and i had multiple shops tell me its my trans/tcase and they even checked my wheel bearings and said theyre all good.....but i still had a feeling that it was the wheel bearings so i replaced the front two and BAM the noise was 95% gone. i gotta do the rears now, i guess all of mine were bad from the previous owner. and i even turned from side to side with no difference in sound, so if yours are both bad you might be having the same issue i did.

Thats what i was thinking about, I wouldn't mind having someone checking out both my trans and the T-case just to be 100% sure. Also did any of you ever hear about the center diff making the same type of noise? I would post up a video but....the car is at the shop, unless i get it back or something but i doubt it.

Believe it or not I had the same whine but it was from my turbo a piece of one of the fins were missing I'm assuming a rock or something kicked up in it, as I got the car with no filter :/
