That sounds like power stearing or somthing else that is belt driven. I olso have a new strange whinig sound, and at first I thought it was the power stering unit, but it wasn't low on fluid. It was low on coolant, but hasn't gotten low since. The whine dosen get louder when I accelerate, but does slightly when I decel. It's probably the loudest at highway speeds. It kinda sound like it's coming from the back of the alternator. (either alt or somthing else near it) but I'm thinking of replacing/upgrading the timing belt anyway just to be on the safe side since I'm over 50000 miles.
