Question on Borgenson power steering box

Well I drained my fluid and filled it with Redline synthetic power steering fluid. The car does not die anymore while I'm trying to turn the wheel but it still makes noise all the time that you can feel. I have an appointment to get the car realigned to be sure that the system isn't fighting itself from poor alignment. Hoping that fixes things. Also it seems to have a catch just before center as you bring the wheel back to center. It don't stop but it changes the feel. I don't like that. Hoping the alignment addresses that. Any thoughts input is appreciated.
