This whine has gotten progressively worse over the last couple weeks. It is definitely coming from the mid to rear. At first i thought maybe it was an exhaust whine. Like something humming. But now I've accepted that its something more critical. Highway speed and the whine is very distinct when pressing the accelerator. It quiets down when I let off and coast but does not go away completely. Is their someone way I can narrow it down to either trans or diff (maybe a rear bearing??). I do not mind doing what is correct to extend the life of this vehicle (250k and runs like a top) I just don't want to start blindly replacing expensive components if i don't have to.
