what is this sound

[Deshi Kicks]

I don't know man, all I know is my buddy's Jeep does the same thing, gets louder with RPMs, doubles sound when he turns, and just whines like a bitch when he's just driving. Could be the pulleys in your vehicle, won't know until you check it out. I was just saying that since you said your power steering pump was already fucked up, go ahead and change that first and it might fix it.
