Steering Issue Lookin for Advice

[Supershooter]

I got my truck stuck in a snow drift last week. After rocking the truck back and forth I hooked on to it with my tractor and pulled in out. After getting the truck stuck in the snow I have noticed that the power steering doesn't work very well until the motor reaches 1000-1100 rpm's. After 1100 rpm's everything works as normal but below a 1000 rpm's its a handfull to steer? Any ideas on what may have happened or what I need to do to fix my issue? Thanks in advance for your help.

Sounds like one we had in our shop a few weeks ago. He got it stuck in some mud, and was rocking it back and forth while turning his wheels. His power steering fluid was almost black from doing that. We put a new pump on, flushed out all the fluid and that took care of the problem. I wouldn't have believed you could burn up a ps pump on one of these trucks that easy.

Easy fix, and the Ford pump is not that expensive.

Tony, could changing the fluid help the problem? I have the truck traded and am waiting on my new truck to get here, don't wanna spend to much on the truck if possible. Are the brakes tied into the same system?

Changing the power steering fluid might help, but I doubt it.

I can't remember what our cost was for the pump thru Ford, but if you are trading it why not just get an aftermarket pump? Just looked it up, OReilly sells a Cardone reman pump for about $60. Don't know much about the quality or longevity of the Cardone but its an inexpensive fix for a truck your gonna trade.

When you apply the brakes, while in park and turning the wheels are you getting some vibration or kick back from the pedal? The one we replaced the pump on was doing this.
