I have a 04 Lincoln Aviator with whinning noise coming from my power steering pump. I have changed the pump twice with no change. Do I need to bleed the lines to get possible air out of the lines or is there something else I need to do?

The noise is constant or higher pitched the higher the RPMs. The noise doesn't get worse when the wheel is turned.
Thank you for using just answer.
Different tech here.
I think you have another issue. I have saw this in the shop before. Turns out it was a idle pulley and belt. I would take the belt off and turn the pulleys. See if you hear the noise coming from a pulley. If no noise put the belt back on. With the motor running spray wd40 or belt dressing on the belt see if the noise goes away. If if was a pump or rack it would make the noise when turning the wheel. Let me know
