Steering no one can figure it out

So have a very odd one on my 2000 Monaco exe turning the wheel to the left is no problem all the way and back to center.

Turning the wheel to the right I get 3/4 to 1 turn then I have to roll even ifís it a 1/4 inch forward or backward to get the wheel to turn more. This is only on a hard surface (pavement).

More RPM does not make a difference. Gear drive, neutral or reverse will not make a difference.

On grass or gravel will turn fine both ways.

I have replaced the steering box. Shepherd to trw. Does it with both.

Alinement is good. Tires are new but have not swapped them.

I have a feeling something is binding up but what?

Odd one to be sure .

Questions .
On road steering performance is fine ?
This is only a paved parking lot maneuvering problem.

You mentioned in gear or neutral , the issue is the same .

If you have the park brake set , trans in neutral, and try moving the steering , with your foot OFF the service brake pedal , is there any difference in the issue?

have you tried having someone turn the wheel while your out front looking up at all the steering components and looking to see if it binding some where? Make sure all the fitting are all greased also chock the wheel while doing this don't want to get run over....

Two things to check.

Jack it up, knock off the tie rod ends, and see if one or the other king pins is seized.

If your steering pump also supplies your cooling fan, it may have a priority valve in the system.
They send pressure to the steering before it sends it to the fan.
Check that the lines to it are not crossed, giving priority to the fan.

Sheesh, Twinboat is a wealth of knowledge as usual.

Since you changed the steering box I would assume you inspected the rubber boot that protects the shaft. It would be hard to miss.

Did you have the steering column cover off to do any re-centering of the wheel.

Maybe you have the u-joint in that area binding one direction.

The reason for inspecting the rubber boot if I can make the story very short. My new RV developed a sudden problem turning one direction. I mean it took two strong arms to turn the wheel. That is a bit of a problem doing 60 mph and trying to get off the freeway. Thankfully I managed to get pulled over.

Looking upward into the steering shaft area I found the rubber boot had been sliced byt some carpet installer from the factory. The rubber boot had managed to drop down, get bound up in the U-joint of the steering column and acted like a rubber band wound up around a pencil. It was so strong it would not allow me to turn the wheel one direction.

I found this issue on another RV when discussing the issue. I was stunned.

So as crazy as it may be, look carefully for anything wound around the shaft. Remove the steering column cover.

I agree, something in the king pins or elsewhere in the steering linkage.
I never turn the steering wheel unless the wheels are rolling. Turning the wheel while the vehicle is still puts tremendous force on the steering lingage. Learned that early on in cars and tractors without power steering.

Wow lots of suggestions I will try to remember and answer the ones I remember.

When driving the steering is fine.

Steering wheel turns fine and loose when not connected to the steering box (no u-joint issue)

My mechanic is checking for a bind this week. I assume will include the king pins.

Neutral no brakes same issue.

Power steering pump seems fine due to left works right does not.

My mechanic is also going to change the power steering fluid this time but he does not think thatís the problem. I am having him do it because I have no idea when last done.
