It usually takes 2 people to see what is up with loose steering, one to rock the wheel inside and one to see what parts aren't moving in sync. There are two u joints on the steering shaft itself that get sloppy before you even get to the steering box and then down under, you have all the tie rod and drag link ends to check. They are allowed rotation movement, but no up and down in the joints. Last, there are the ball joints on the wheels themselves.
Mine was totally unsafe on the highway over 60 mph when I got it, yet 'all' the parts were within safety inspection 'safe' limits. Add them all up and wow, it would tack in the wind and when a transport went by, well you wanted to be holding on....
So I ended up just replacing all the half worn parts and now my CJ is stable at any speed.
That said, if the box itself is sloppy, it can be reset, it is just a 'very' touchy job to do. As mentioned, you have to have an inch pound torque wrench and have the box disconnected from the steering and pitman arm outer end at least so the box's guts can turn free with no load on them.
If you try to adjust it in the vehicle, well, other than the end plug where the steering shaft goes in which usually is the place to tighten up the left right slop on the input shaft, you will likely not get it right which will usually wear out the box really quickly.
On the power steering box to get rid of side to side input movement, you loosen off the big lock nut where the steering column shaft goes into the box and use a tool like a grinder wheel removal tool with 2 pins in it (or a hammer and a center punch tapping real gently) to tighten up the adjuster plug snug. You then back it off 1/8" to 1/4" or until the shaft just gets a slight slop, then tighten the big locknut back up. That is about the only adjustment I know that can be done with everything hooked up.
