I had a squealing noise in the power steering pump when I first started the car in the morning. It would squeal about 5-10 minutes until the engine warmed up, and would finally stop. I decided to replace it today, an cannot seem to get the air out of the system. I have raised the front wheels off the ground and turned all the way left and right (with the engine off) at least 40 times. I am wondering if my connections are tight enough. I don't want to break a bolt. Now, when I start the engine, I get a loud whine when I steer back and forth. The fluid is at the proper level. I have seen some advice someone gave, to remove the reservoir and clean the screen with brake cleaner. Have not tried that yet, but before I leave, does anyone have any thoughts?
