There's a way for the dealer to test the pump's pressure without replacing parts to do a diagnosis. They could connect a tee fitting in one of the power steering lines with adapters, then connect a pressure gauge to see what the line pressure is. I don't know if they are willing to do this prior to throwing expensive parts at it.
