Do you need to bleed a power steering system after repair on a 1995 Dodge Stratus and if so how?

The book says to jack up the front end fill the reservor and turn the wheel full left to full right, continue this until the system stops squeeling. This took me 10-15 minutes and it still squeels at the full turn radious. Make sure the cap is off and not over full. This bleeds the air from the lines. Make sure to fill the reservor when finished.
