They have a Viscous coupling in the transfer case . they are known to go out . however, it is not uncommon for the front to not pull at all if the rear is not engaged or the DS is missing. This is because of the VC , the split for power is something like 60/40 with no spin the VC gets confused ???? if it detects no movement to the 60 side is me guess. Alot of folks pull the AWD X-case and put in a 231 in its place. If he needs a ZJ rear there are a few down at Mitchell's that can be had complete for a good price.
