Steering Locks up when Brakes applied
Well I have a Real problem, yesterday when I was driving I was making a slow turn as I applied the brakes. What happened was the steering got real hard to move, when I stopped I tried to turn the wheel with my foot on the brake but it took two hands to make it move. As soon as I took my foot off the brake, everything was OK.
I called North-Side Ford here in Portland, and they said I had a Vacuume leak???
Well today I took my handy dandy Vacuume pump out to the truck and connected it to the Vacuume hose manifold, and I took a -10 pound draw on the system. It held for 15 minutes, then over the next hour it drained down. So I don't believe I have a leak. And why would putting on the brakes affect the steering???

Putting on the brakes would affect the steering because it requires more vacuum to help the booster which makes the vacuum pump work harder which slows down the engine which makes the power steering pump turn slower.
10 inches of vacuum isn't all that much, I don't know if diesels are different but a gas engine will pull 18 inches at idle. Your PS pump may also be on it's way out and doesn't work as effectively at really low rpm. I'd try running more vacuum in the system and see if it holds.

I cant remember which belt runs which pulley. Look under the hood and determine if the power steering belt and the vacuum pump are the same belt, but I dont think so. Your power steering belt may be slipping and that will cause the steering to be pretty hard. I would first suggest you check the fluid level in the steering reservoir then the tension on the belts, this is the cheapest starting point. The belts may not be squealing but are still slipping if they are older belts. If you change one, go for the gusto and change them all. Let us know what you find and we will attack the problem from there.

Hi,
When this happened I took it right over to my machanic, he had just changed all the belts. And the day before this I had the engine serviced and all levels were full.
The power steering pump in on the other side of the engine, belts are tight with no slipping, the Vac pump is run off the Alt.
The thing I don't understand is, whats the connection between the Brakes and the steering?

The only thing the two have in common is the crankshaft which drives them both. If it's still doing it I would try holding down the brake and giving it a little gas, if the steering gets easier you know it's something with the pump, either it's slipping or just doesn't have enough rpm to work correctly. Maybe your idle is set a little to low. I'm just tossing out ideas and it doesn't hurt to double check a mechanics work, sometimes they get in a hurry and miss something.

Well I went out and started it up, checked all the belts. But when I tryed to turn the wheel it wouldn't turn. So I took off the power steering dip stick, and checked to see if the fluid was moving in the tank.
It wasn't moving at all, so I'm going to replace the pump today.
Now this might be a good thing, my wife says se doesn't want to be stuck out on the road with a trailer and a broken truck!
And I was just looking at a New 04 Super Duty Diesel yesterday!!

Good job,
I just read the post's
Glad to see it up and running right again.
Was at Mudfest yesterday, playing with my Bronco..
Saw some older Ford idi's still bringing the play toys in...
So who knows about when to get a new one...
But one things guaranteed if you do buy one.
You'll give up more money real fast, and it goes down in value..
Even if your truck gave out today...
It wouldn't cost you as much in when driving a new one off the lot..
Anotherwords, if you really, really want it..
Just make sure you do... Then i do understand..
Good luck...
