Re: 04 f250 looses power steering
Possibly low fluid level causing bubbles to get into the lines. Possibly overheated or really old/bad fluid. I'd start with making sure your belt is good and not glazed over, then make sure your fluid level is topped off properly, and then maybe consider doing a flush. I know several guys have noted a big improvement after flushing their power steering system.
