My p/s pump is about to go. It makes a low-pitch hum when I'm stopped at lights, but if I turn the wheel to the right a bit (under load) the sound stops.
Also, if I make a sharp right turn and hold the wheel to the right I hear this small thudding noise like something is tapping against the inside of the engine compartment...
