So since i put new tires on my truck, i have noticed that the power steering doesnt work to the right at all, but works fine to the left. So bad that i got a ticket cuz i tried to make a wide turn to make the turn, anybody ever heard of this? is my steering box going or my pump?

 

A ticket for turning radius? I hope your going to appeal that. My guess would be the box but I have no clue. I've never heard of a steering box only working in one direction and not the other.

 

If its got power to 1 side then the power works , so whats maybe not working is the valves , give the system a flush and see if it gets better.

 

In general, a power steering system has a shuttle valve in the steering box and a double acting hydraulic cylinder tied to the steering linkage. When turning left, the shuttle valve cycles over and applies hydraulic pressure to one end of the hydraulic cylinder. When turning right, the shuttle valve cycles the other direction and applies hydraulic pressure to the other end of the hydraulic cylinder, letting the opposite end (the left turn end) bleed.

It sounds like you could have a bad valve or broken hose that's only applying hydraulic pressure to one side of the hydraulic cylinder.

FYI,
I bent my steering stabilizer once and could only turn one way, might want to check the easy stuff first.

 

Technically its not a shuttle valve its a torsion valve A spring steel bar that twists under a certain load when the load on the sector shaft is greater than the force required to twist the bar you get assist (from the pump) any other time the box works mechanically and simply cycles fluid

I would say it IS possible to have the torshen valve working one way but not the other due to some crap stuck in the valve (there CAN be all kinds of metal floating around in the system) but not likely to stick one way and not the other

you may have a crack inside the box allowing assist pressure to leak to parts other than the intended destination OR you may have a blown seal ring on the torshen valve

 

Sorry. I was at the office and didn't have a shop manual. I was only trying to explain conceptually how a power steering system operates. That's why I introduced my post by saying, "In general...." Again, I apologize for using a name which perhaps doesn't agree with the shop manual even if it did explain the function.

I wasn't trying to be a **** about it just didnt want any one to get the wrong idea as to whats going on

 

I've had a same problem on my old 1972 Power Wagon.
It's a control valve inside the power steering box. It's held in place by a pin. The pin eventually get loosen up and the valve doesn't function properly any longer. It hard to explain the design of the power steering box. I've rebuilt a few of them... not a fun job!

 

doyou mean in the steering gear box?

 

Yes... It's inside... It's a round piece inside with slots in it. Wthe the steering shaft turns left or right the valve open to feed pressure to on side or the other on the piston. This round piece has a pin through it and sits on the steering shaft. The shaft itself is spring loaded to center the valve. But if the pin wears out a bit the valve hangs up in the left or right position.

At this point you have only one choice to replace the steering box. You might try getting a used one at a salvage yard.
