If your slot is into the nut and you are sure everything else is tight than the box is past adjusting and is worn out.
What other adjustments are there? I know there are some set up procedures when the box is assembled but I am not aware of any normal field adjustments other than the adjuster screw.
The procedure is in the FSM. You need a big/special spanner wrench.
Thats what I thought you were referring to. I would have to read up on it but I did not think that was considered a normal field adjustment. I might be wrong but I thought is was just an assembly adjustment.
I just looked that up and see what you mean. I remember doing that when you could see the worm gear moving in and out of the box by the coupler or rag joint. But that was a long time ago. It would be worth the posters time to watch as someone rocks the steering wheel. As I recall most of the time the boxes were pretty beat up because no one ever checked them for being lubricated. They ad been run dry for years and we ended up replacing them. We always had a lot of like new manual boxes on hand as Mopar had a power steering conversion kit and we did convert a lot of A-Bodies and F-Bodies back in the day.
