99 superduty psd, problem please help!!!

Yesterday I was on my way to get fuel, and while parking in the spot I started smelling burnt rubber and heard a loud squeeling noise. So I killed the truck and popped the hood and realized that the belt was shreaded. After some investgation, I noticed that my tensioner had poped off. So I call a friend to come and pull me back to my shop to replace the tensioner and belt. After relpacing and starting the truck, I thought everything was fine. But when I went to leave, I could hear the powersteering pump was loud like it was out of fluid so I stopped and checked it. Everything was fine. I guessed that it was just some air in the system, so I continued to drive and noticed that I could hear the same noise when I hit the breaks. And now I am scared to drive the truck.

What is going on, why do I hear the same noise when I hit the breaks? Do I need to replace the powersteering pump or what? Any help would be great.

Thanks

I had the same problem with my 01 powerstroke one day. I had my wife turn the stearing wheel while I was under the hood and a little stream of power stearing fluid shot out of the pressure line that hooks up to the master cylinder (your brakes). It made the squealing sound when you turned the wheel and hit the brakes becuase the pressure line was leaking. I replaced the pressure line and have not had a issue with it since.

Release the steering and it will seal back up again. The brake booster is hydraulic on the later trucks and powered by the power steering pump not engine vaccuum like on the earlier ones. Fix the hose and you're back in business.
