Should a Stock Steering Pump on a 99 F250 Turn 38's?

[FLYING BONES]

...cause mine don't turn them tires.

I'm going to have to pull the water pump soon, thinking it's time to get this issue fixed as well. Would a f350 steering pump bolt right up and have more turning power? Or is the stock pump ok but mine is shot?

Thanks again!

Not sure...but mine won't turn 37's if I'm not rolling at least a hair. Been that way since I put them on. They are known to be relatively weak so I haven't bothered to replace mine. Been that way for 4 years now.

I had a PSC pump with a stock box it moved 46s the the pump exploded so I went back to stock and I turned 37s like nothing,

big tires or stock, the original pump might be ready for replacement... I have no lift, and standard size tires on my F350 and have to be rolling to turn the wheel... this seems to be a common problem. The advice I've gotten is replace the PS pump, and it should cure, or at least help, the problem. Good luck...

Thanks for the input.
Dereku - If you turned 37's like nothing it makes me think I should be able to turn 38's, although they are 38-14.50's.

Is there a difference in the F250 and F350 pumps that anyone knows of? Seems like the F350 may have a more powerful pump? Wondering if it would bolt up.

No idea I had a new PS pump from ford. I put it in last year, and a reman gear box. Mine all took a dump at the same time.

I have a f250. Maybe you just need to clean your out and put new fluid in. I run synthetic. You could have a clog or something somewhere.

There's no difference in the pumps. The power steering on these trucks have never been something to brag about...

That's a good idea...is there a way to dump the PS fluid?

Its easy to flush the system. Most people go to a synthetic fluid. Look here
