This problem has plagued fords for years. I would say in general, it is more of a design problem than anything, however, periodic maintenance and in-line filtering will go a long ways towards helping this problem. In short, these power steering pumps, like all others have a bypass valve in them that keeps the pump from blowing out seals at high RPMs. Over time crud builds up and these valves get stuck in the open position, meaning that the fluid is in bypass mode all the time, and until you rev the motor you don't have enough overall fluid flow to operate things properly. As for rebuilt pumps that act the same, it goes back to design, and the design can be tweaked a bit.
There are a couple things people have done. One, is to take the valve apart and clean it, and while it is apart there is a tiny spring in side that they stretch to force the valve to stay closed longer. The second thing people have done if the spring mod is not enough is to enlarge a specific orifice that will let more fluid flow. Gotta be careful not to enlarge it too much though or it WILL blow seals.

After all of this, install a filter in the return line of the steering system. Magnefine has been used with a decent amount of sucess. http://www.emergingent.com/magnefine/faq.htm

 

I got a 2000 with the V-10 and 38inch Ground Hawgs. The truck is really hard to steer at a stop. On top of the over sized tires the addition of dual steering stabilizers dosen't help.
I hear this is a common problem. I read some where of changing the pump with a GM pump. Dont remember.
I think I read an article in Offroad magizine or FourWheeler.
I'll have to look around and see if I can find it.

Miker67....I tried to PM you, but the site won't let me because I havn't been a memeber long enough!

What you have said makes perfect sence to me! could you tell me more about the "specific" orifice so I can print this and take it to a Mechanic to understand how to do what you are talking about??? If you want to PM me, please do!!

Thanks to EVERYONE who has replyed about this. I am feeling much better about it!

 

I will try and take some pics and post them in my gallery. I will email you when I have been able to do this. May take a few days though. Just a friendly note, putting email addresses in posts is a no-no. For your protection, the mods will probably be along shortly to remove it.

-Edit- Until your PM function is activated you can talk to others on the side by asking them to PM you with their contact onfo/email address, and initiate things that way.

 

So sorry!!
