Ok I have a question. I have a 1991 Cherokee 4x4 that had a NP231J that blew up due to a bad front driveshaft. I’m putting an older 231J from a 1989 in it from a Jeep that had the vacuum disconnect front axle. According to Novak’s website, it says the older 231J doesn’t fully disconnect in 4x4. I have a lockrite locker in my front axle, so that’s gonna be a bad deal. Is there a way you can make an older 231J disconnect all the way so as to not cause any issues? Planning on putting locking hubs on but that won’t help me if the transfer case never disengages. Any help on this? Or anyone that can guide me in the right direction?
