Major steering problems

[AKDREDGER]

Ok guys need some help here. Truck has been at Ford for 2 weeks. I am into it $2200 and its not fixed. 2006 F350 6.0 6" Lift, 37" toyos dual steering stablizers. No other mods. Not off roaded, mostly highway driving. 45K miles

Now the problem. Steering goes away at stop with brakes on. Arnold Swartzaneger couldn't turn the wheel!

Dealer installed new steering pump, steering gear box, and hydro boost. Called and said it was good now. Drove 10 feet and stopped and tried to turn wheel, no steering. Went back in and they are going to try a new pump again.

Anythoughts on this matter? It steered fine until just recently, first started with a little jerkiness then went to complete unturnable. Only at a stop, fine when moving, unless going down hill with brakes on!

Any help would be appreciated.

Can someone try it and let me know if your truck does the same? Press the brakes hard then try to turn wheel. thanks.

Mine does the same thing! I changed the power booster, didnt help any. When you hit the brakes on mine, it wines really bad and you can feel it in the pedal. Turns like **** when barely moving or stoped and anytime you get on the brakes hard. Somebody give us some answeres as mine will be in the shop soon to try to fix it.

Ford dealer here cant figure it out says its normal. Bull. Going down a bumpy dirt road with the brakes on & off, steering doesn't work smoothly and its dangerous. I am going to take it an independant powerstroke shop for diagnosis. I ask several F350 owners I came across yesterday & today and theirs turn properly. What is the deal? I checked the pump & belt while running just incase the belt was slipping, it wasn't. I have spent alot of money for no resolution. Mine doesn't make any sounds or vibrations. Just doesnt turn with the brakes on.

mine has started to do the same. never used to. i have not looked into it yet but i know something is up. it is not normal. some say it is cause we have bigger tires, but like you and i have experienced, it didnt do it before. i will try to find out what it is as well.

I have found dozens of these problems with all makes on line. No one has posted a solution yet! Going to flush the fluids and go with synthetic today and see if it helps. All parts but the cooler & hoses are new.

If you want it fixed you have 2 choices, either get rid of the hydro boost or get a high pressure high volume pump, your using the pumps pressure on your brakes and there isn't enough left for the steering.

Where can I find a high pressure pump? thanks.

IAM HAVING THE SAME ISSUE AND I CANT FIND A SINGLE THING TO CORRECT THIS AGR PUMP PORTED HYDRO BOOST NEW BOX THIS ISNT RIGHT ANY SOLUTIONS ????

Yes. The solution is to go to a hydraulic ram assist. That will make all of your problems go away. It is common behavior with these trucks when you start getting into 37" and over tires for the steering not to be able to handle it.
