With the NP247 case, you can run for a short time with the front removed, but don't do it for long.
With the 93-95 ZJ's you fry the Viscous Coupler (front shaft power transmitter) if you remove the front shaft. The 96-98's don't, but all ZJ's use a NP249 which is slightly different than the NP247. Lately, the guys at JF have posted a few issues with the NP247, and it failing. Luckily a NP242 from a 99-04 WJ with the 4.0L is pretty much a direct swap, and gives you a 2wd option in the case.
Good luck tracking this sucker down. It can be a pain.
