You would need to post the pics up of the rest of the diff parts for us to see condition.
Very much doubt this can be diagnosed here, if the diff is not tightening when the screw is turned then it can only be the screw, the nut/holder or a damaged thrust bearing/spring, assuming that both drive rings are in one piece and all 14 balls are fitted.
but i would also look at the slipper components too and check the driveshafts are straight and still in one piece and free to articulate as they should.
I take it you have given it a good clean already?
The best thing to do would be to build it all back up as in the video i linked, but flip the worn plates and check you have diff action before building the whole gearbox back up.
Make sure you have a copy of the manual to follow with video too, can be downloaded from TLR site
