Well, I have new gearbox and hydo-boost, must be the pump? The pump is the last thing to change! I drove my friends truck it was an 01 and it turned like a car and mine is still stiff, now does anyone have any suggestions on pump? where to buy etc...

 

Did you check your steering stabilizer ?

 

Nope, it's a classic issue for the later 7.3's! I spent over 8k trying to fix this problem with one of my trucks and just gave up. I had replaced everything except the steering wheel with no luck. Tie rods, ball joints, power steering pump (twice), hydro booster, hydro booster lines, axel shafts, 4x4 hubs, gearbox (twice), brakes pads, calipers, and rotors.

Correct me if I'm wrong, but if you have the truck in park and rev the engine up the problem goes away. But if you have your foot on the brake, or engine at idle its next to impossible to steer the truck, right? I am so fed up with it when I was backing trailers into my shop I don't even use the truck for much anymore. On top of hard steering while trying to park, imagine having a 9'2" Boss V-Plow hanging on the front to make things even harder.

 

Did you use tranny fluid or power streering fluid

 

i had my pump replaced friday and still the same problem. drove around the block and brought it right back to ford. The diesel guy who put it on told me it was cause i was running to big of tire for it. i asked what kind of bs is that so they checked everything out and couldnt find any problems so going to undo the steering stabilizer tomr see if it is the problem.

 

It shouldn't matter FWIR the ATF is only bc it runs quieter, not bc it is better for the system.

 

well in that case the only thing for me to do is change the pump! yah......

 

Yep... I have had this problem with mine now since I bought it... I remember reading somewhere about a high volume pump??? Can't find the link now....

 

This one? I've got the same problem too.

Here's the link to the pump from AGR. I think Autozone can get it. maybe other auto parts stores can as well.

Hey just wondering. How the rest of the front end components?? Ball joints front steering u joints?? You don't have anything ceased, or ball joints
that have been tightened to much?? I have also seen alot of bad rebuilt steering boxes. How big of a tire are you turning..

 

Oh, I forgot to tell you guys how much better this gets.... after I spent all this money trying to fix this truck the service manager, Jon hands me a printed page off of his computer from Ford. He had highlighted my problem of hard steering and underneath, where Ford's fix for the problem he had highlighted "....there is no fix for this problem."

The only thing that I've been told to do is buy and install a hydraulic steering assist kit. Haven't gotten to that yet, but I'll let you guys know if I ever do.

I thought that was the hydro-boost? My truck has this!

 

I was thinking something more along the lines of this

hydrosteering

 

Nope, hydroboost provides power brakes bc your truck doesn't burn gas (thank goodness) nor the vaccum normally used for power brakes.
