Help no four wheel drive

Hey everyone. Bought this jeep in July of this year. 4hi worked when I bought it and had an understanding of linkage not allowing 4lo to work. My thought at this point " I can fix that ok and I'm not planning on needing 4lo soon". Well, now I have no 4 wheel drive... light not letting me know theres any engagement(this worked when I bought it) and when pulled back to 4lo position, it's almost as if it's in Neutral. Same thing with 4hi, it does not hold in 4hi position... I have to pull it around that small bend and it will sit there, however still not engaging to 4hi. Not sure where to start my search... any leads would be great as I'm trying to prepare it to sell it and am up ***** creek w/o a paddle right now.

Sounds like the linkage is just loose. You need to get under there and check it.

There is an adjusting bolt that secures the linkage rod, so this doesn't happen.
Search for youtube on adjusting linkage for TJ's.
Pretty simple. Place shifter in 2H, loosen bolt head, manually move transfer case shifter into 2H, tighten bolt, move shifter into 4H, N and 4L then back to 2H.

Would start by whether anything just looks funny. Stuff not connected. Bushings torn or loose. Then I'd focus on the trunnion nut. Sounds like it may be loose already but that's where you'll probably need to make adjustments to get things working again assuming this is the problem. It can help to have somebody else sit in the jeep and pull the handle while you are underneath so you can see the linkage moving, slipping, doing nothing, etc.

Ok... thanks guys I'll look at this... is the trunnion nut closer to the handle coming down from the body?

So... the one video did not give a very good explanation of the process and the other didn't look like the same components for the linkage... do you have a link for a good video?
