If the noise is coming from the pump, the problem is with the pump.
The steering box itself will NOT create a noise in the pump, since this system uses the slave cylinder/ram system...not fluid routed thru the box.
You need to make sure the ram is adjusted properly before going any further with your diagnosis. Jack the front end up, and disconnect the ram end from the bracket on the frame(driver's side). Take the cup/cover off of the end of the steering valve to get to the adjustment screw. Start the engine, and see if the ram moves in either direction...if adjusted properly it will NOT. If it moves in either direction, turn the screw on the valve in both directions a little to see which way it needs to be turned to get the ram to stay centered, or not moving in either direction. You can do this with the ram connected to the bracket, but disconnecting it keeps you from getting your wrist broken if you happen to start the car with your arm thru the steering wheel...like some folks do. If the valve is not adjusted properly, when you start the car it will snap the steering to one side or the other quite hard....and turning the steering wheel with it...ouch.
Get the ram adjusted first, and see if that helps with the noise. If it does not, and the car drives/steers correctly, then my money is on the pump being faulty.
