I'd get the Jeep in a crossways bind and try it. Sometimes a bind will unbind if bound. Does that make sense. I know this example is electronic but I had a cell phone that quit transmitting after I dropped it. I could hear but could not be heard. Anyhow, I had seen it drop and how it landed so I dropped it exactly that way again and it started working again, never to give me trouble again. Sounds stupid I know but just try it. Same happened with my ol Chevy pickup. I got it in a bind, the syncronizers were worn and it popped out of gear while in a bind. I couldn't get it to go back in gear until I literally got it in a big bind. Do you know when/what the situation was when it no longer worked correctly? Were you in a bind? While doing so, I'd try to move the shift lever from left to right (in the little bit of play you have). There seems to be a little invisible "track" it needs to move along when shifting it so maybe that's it.
Then again, don't pull it hard. Apply pressure but work it from side to side. If all that fails, BREAK IT OFF!!! No, just kidding. Take it in to the dealership.
It worked fine for me this past summer/fall when I used it while camping. I was towing my tent trailer the last time I used it. When winter started to make its presence known this past October, I tried to engage it on paved ground doing about 40km/hr. It was really tough to engage. I did manage to get it engaged a couple of days later after REALLY yanking on the lever. Once it was engaged, it ran fine, worked great and I heard nothing odd or disturbing coming from the driveline. I should have left it engaged all winter, but stupid me, I shut it off after about a week and have never been able to engage it since. That was in November.
Fluid was changed last summer and has been checked recently. It's fine. I'm out of ideas.
