I have about 10 degrees slack in my steering either way and wondering if there is anything I can do about it. I have checked all other steering component and the only movement I see is the pitman arm attached to the steering box. If correct there is some type of adjustment on top of the steering box. It does have power steering. Any advice.....

 

You could tighten the adjustment screw on the gearbox. However, I would say that you may need a new box in general.

 

To adjusr do I just loosen the nut and then tighten down the screw until the slack is gone? The threads are sticking up at least an inch above the nut.

 

I believe so

 

Only tighten it about a quarter turn at a time. Then drive it down the road and adjust it more if it needs it.

 

Do not drive after the adjustment that's a good way to end up in a ditch. After tightening a 1/4 turn jack it up and turn it lock to lock to check for binding. You can cause the box to lock up if tightened to much. The box isn't wore as much when you turn left or right most of the slop is in the center. Adjusting the sector screw on the top isn't the only adjustment either. Give Red Head steering gears a call they will help you and can provide you with a great rebuilt gearbox if you want it.

 

Do you mean pitman arm is moving on gearbox shaft? Have you made sure the nut is tight?
If its loose the splines could be worn on the pitman arm already.

 

When do you see this movement? Is it while someone else is rocking the steering wheel?

I notice it while driving down the road and can see it while moving the steering wheel and watching the movement of the tire.

 

Well, a good way to narrow down where the slack is would be to have someone sit in there with the engine off and move the wheel back and forth like they are a kid playing bus driver. While they do this, pop the hood and look at all the movement going on.

If you see anything moving more than it should, there's one of your slack areas. One of the big places would be the rag joint; you'll often see the upper portion of the shaft rotate much more than the lower portion.

Dont just stop under the hood, though. Look under the whole front of the vehicle. Bushings, ball joints, all that good stuff can all have play in it and is a good sign that it may need some attention.

If you narrow it down to the steering box, though, boy are you in luck. The link above goes to a group by to the best rebuilt box you can put into your truck and it looks like it all kicks off on the 15th (I think) of this month.

It's a hundred times better than fooling with that little screw on top of it; I've never had a bad experience with it, but other threads have mentioned having problems with the steering failing to re-center after too much adjustment.
