Steering box rebuild

[Gerry]

How complicated is it to do a rebuild? I have the box out and thought it would be a good time to do it if needed. I have never driven my truck so dont know if its loose. It didnt leak.
Appreciate all input,
Thanks,

These boxes are really simple. Just a worm and sector. If it's not leaking I would tend to leave it alone. The power train body and frame book has the best info on it.
