The only complaint I have here is not about the pump itself, but the fact that the pump's design allows for the power steering belt to be routed around the motor mount to change the belt, you must remove the engine mount and jack up the engine with a block of wood. Terrible design. But back to the pump. Thanks to this detail, my engine compartment differed in noise level day and night when I turned the steering wheel. The hum is gone, the pump is working properly.
