Fellow Power Strokers, I need some help to figure out an issue I am having with my 2005 F250. While driving today I lost brakes. Pedal became very hard and I could barley stop by pushing as hard as I could. Once the issue started it never went back to normal. I had been having steering issues, hard to turn the wheel while stopped or just starting to go. The pump is making noise when trying to turn while stopped or moving slowly. The truck does have 37" tires on it with two steering stabilizer shocks. I bought the truck late last year. I was told that it had a new pump, new hydro boost, and a new steering box. I have not flushed the system nor do I know what fluid was originally put in it. I am planning to flush and replace the fluid with Mercon ATF but want to hear some of your input first.Thanks for any help that you can provide.
