Power Steering Issue

I have a 99 F250 S.D. with a 6.8 V10 in it. A week ago I replaced the power steering pump as the original was leaking pretty badly thru the front shaft seal. Problem now is that when the truck is sitting still and you try turning the steering wheel it is like there is no power steering but if you bring the truck off idle a ways it works fine. I am just wondering if there is something I may have missed doing when replacing the pump. Any info would be greatly appreciated. Thanks in advance

Are you sure you got all of the air out of the system ? Have you checked your fluid level again ?

Well you turn the steering wheel fully to one side and then to the other side a few times, and this’ll bleed the air out, you want to check the fluid level while doing this and add as needed.

I just replaced the psp in my 99 V10 also. It was leaking like yours and if sitting idling sometimes it was real hard to turn. I thought Id spring for a new unit from R/A that had a heart by assuming its the hot item in new pumps. No surprise when I opened the box, made in China Like the rest of todays crap parts. It dont leak but the steering whines a tad when turning unlike before. I also bled it well and drove it 250 miles the other day, steered fine etc. Id guess the Chicom crap doesn't produce the pressures the ford one did.

Just made this same reply in Apache's thread the other day -- jack the front up so the front wheels are off the ground. With engine off (and key to ON, so you can turn the wheel), rotate back and forth and look for bubbles. It should bleed itself after going back and forth about 10 times.

That being said, I think it is a common problem with these trucks having a lack of power when not moving, like trying to get out of a parking spot. Mine does it even after replacing the pump with a Ford reman... seems to get better after its warmed up.

Ok, I dont feel so bad now that both of your trucks kinda do the same thing with idle speed hard steering on occasion.
