pitman arm help!

My steering keeps getting lose. I have found out that the pitman arm keeps coming loose. When i have the wheel turned i can see just a slight movement on the pitman arm to shaft. I have used a three foot bar and the correct socket and the nut is on there as much as the three foot bar will let me.

I do know that i have some rotational play in the ball joints of the currie HD steering bars. The trac bar is an adj RE bar with good bushings. I also looked at the control arm bushings while turning the wheel and they are all solid.

The pitman arm has come loose 2 times in a month (still tight but able to see play between the arm and shaft)

How do i set the arm on the shaft?

Also i get a very light sopt in the wheel. Lets say the wheel takes 2 pounds to turn it. At the 11-1 position its like .5 pounds to turn the wheel. When i tighten up the pitman arm nut it gets better but not gone. The ball joints dont move in and out but they do rotate a bit when the wheel moves.

I believe my pitman arm has a lock washer on it. If yours doesn't, it should. If it does, it may be flattened out and not doing it's job. You can always add some lock tight to the pitman arm nut to keep it from coming loose on you. Being that the dead spot gets better when the arm is tight, hopefully torquing it properly (with a torque wrench, not a breaker bar) and keeping it tight with a new lock washer or lock tight will fix that. If not, do another dry steering test and find the loose component. Don't forget to look at the track bar axle side mounting hole. Good luck!

I didnt see any play in any bushing. The ball joints rotate a bit but they do not have laterial play.

When the wheel is mover the jeep will rock a bit. I tried to look as to what is moving but i didnt see and control arm movment. The trac bars seem fine. I can clearly see the body roll a bit.

If it has come loose a few times, I would be worried that the splines are damaged on the box or arm, or both.

Is there a lock-washer under the nut? The nut should be torqued to 180 foot-pounds. My guess is you probably reached that if you had a 3' breaker bar.

It may have lost some of it's "spring". I think you'd be better off replacing it if you can find the correct size at your local hardware store.

Torque to Spec Using a Torque Wrench,It's likely not as tight as you think you will be suprised when you put a Torque Wrench on it how much you have to turn it to get it torqued to Spec.

X2....if you tightened it all you can with a 3' bar, then you have torqued it more than you ever could with a <24" torque wrench. I have a suspicion that you're due for a steering box, especially if there are light spots in your steering.
