So I replaced the rack and during the process quite a bit of fluid drained out of the lines. When I started up the car the power steering pump was making some noise so I shut it off for a bit. I tried to read about how to get the air out of the system.

I probably did it wrong but with the car on jack stands and off I turned the wheels lock to lock a few times. Then I started the car and turned lock to lock but it was making a noise and the movement got kind of bumpy and I shut it off. I checked the level and it was a bit low and had some froth.

How should I proceed? I want to make sure the new rack is bled and there is no air in the power steering system. Should I follow the fluid flush procedure how-to on here?
