Power steering whine/ groan

[Fox Hunt]

Okay I'm going to post this here cause the problems section doesn't get as much traffic.
So a while back my trucks hydroboost was leaking so i had it replaced under my extended warranty. Then a few days later it was leaking ATF fluild turns out it was a bad line on the power steering pump. Had that replaced as well. No the leaking hose drained my reservoir and I drove to the dealer 3-4 miles with no power steering fluid. They changed the hose and refilled the fluid but now my get a whine/groan idling and when I turn the wheel or put the brake pedal to the floor it gets even louder. brakes and steering work fine and but I have this noise. I did jack up the front end and turn the wheel back and forth all the way with the cap off trying to maybe get some air out but nothing seemed to change. So my question is what do you think is making the noise and if everything works right is it worth changing?

How tight/hard is it to turn the steering wheel while not moving?
Engine started.

It's normal to hear it whining after it has been replaced or there hasn't been any oil in it. The more you drive it - it should get quieter. If it DOESN'T get quieter over time than your pump is going out. My pump used to whine like that ALL THE TIME, drove me INSANE lol. I also couldn't turn my steering wheel if I was sitting still. When I did my head studs and gaskets I replaced the PS pump and it whined again REALLY bad like before, BUT it was working and over the course of about a week or so it really started to get quieter and now I can't hear it at all.

Also DON'T put lucas additive in there. These PS pumps and Hydroboost systems run on ATF not PS fluid.
