My 92 has the 242 also. I just leave it in "Full Time" from late October to about mid March.
I haven't noticed a difference in either in snow really either. The XJ seems to "handle" better in FULL TIME in snow for me as there is no "binding" of the driveline so the wheels wont break free on turns.
Just my .02.

Yeah ok so..............with my limited knowledge of XJ's in general, instead of holding out for a later year model, I ended up buying a 90 RENIX with the totally retarded cooling system (which I've since upgraded), and an NP231 t-case (which is perfectly fine since that's what I'm used to).
The truly annoying thing though is, having 2 open diffs. This little drawback sucks some major *** in the slippery stuff.
My friends 92 2wd had the Chrysler 8.25, which I would very much prefer over an open D35.

Part time actually creates a "slip" between the fron and rear diffs. Use full time in the snow. Gone are the days when aMC/Jeep used a viscous coupling i their transfer cases. 1986 for the XJ and 1984 or 1985 for the eagle. You could push snow with an Eagle til it stalled. But, you never lost traction.

No "slip" or differentiation in the transfer case. But, the axles require "slip" as in loose surfaces. With the full time, there is no slip at the axles.
