By the way I'm talking CJI've fixed the DW for about 40 years sometimes it's as simple as adjusting the ball joints both upper ball joints have adjustable sleeves in them to get the right tension on the knuckle. They can't be real sloppy and must have drag on them but not tight. Then it could be the steering gear worn out or it has come loose on the frame, they were known for cracking at the frame where they mount. You have to have a good steering shock but that doesn't cause the DW if it's bad. Check all your tie rod ends for play, have someone shake the steering wheel not running and watch the tie rods for being sloppy. I started working on Jeeps when I was 13 and now I'm 71 I've seen a lot but you never know it all.
