Ah so it's sticking in part time when your going from full time to 2wd. Your first post was not clear.
I have a 2000 xj along with my 06 CRD both with the 242 transfercase and they both stick in part time as I think your saying. It even happens after both had new tires all around. Yes the tires all need to be the same with the same air pressure. You can consider this "normal" for this transfer case
The CRD maintence even calls for rotating your tires when you change oil every 6000 miles too
It's because the shifting fork is not directly coupled to the shift rod. It's spring loaded

So when the planets all align with mars and jupitor it glides right in
Here's what works for me. When your shifting and still moving pause in part time for a hundred feet or so then put it in 2wd. Works every time in both my jeeps
Everything else recommended like backing up, bliping the gas pedal, shifting tranny to neutral or standing on my head do not work for me

Yes I inserted "non" unintentionally
