Hey,
I have a 1986 XJ that I put a 1993 ZJ drivetrain into, which includes AW4 and NP231. Now my XJ has a vacuum disconnect front axle, and the old NP207 I had had internal synchronization mechanisms to enable me to kick into four wheel drive up to 60 mph according to the owner's manual.
Well, my new NP231 is made for a ZJ without the front disconnect, and therefore assumes the front driveshaft is always spinning. It doesn't have any synchronization. If I try to engage 4wd withouth standing completely still, the transfer case makes horrible scraping noises... I haven't tried that more than once.
I've just read that the NP242 uses the same housing as the 231, right? So that drive shaft lengths are the same.
Well, my question is really: Did the NP242 come with front axle disconnect? I.e. do they exist with that synchro feature? Or did only the NP207/231 have disconnect? If NP242 did come with the synchro thing, I'd like to swap to one of those in the future, perhaps...
