Answer
You should never hold the wheel at full right or left. That put full pump pressure to the rack and the rack cant go any farther.
It will always hum/buzz a little at "full turn".

You may have air in the system.Fill it up and turn back and forth 10-15 times then shut off
wait 15 min and do that again. then check the level.

If it still makes noise then, you may have gotten a bad pump.
