    If you have been pondering the idea of rebuilding your Transfer case do not be afraid as it's easier than you may think. All you need are some basic hand tools and the special ring pliers. In this video I hope I clarify the steps involved in taking apart the NP231 Transfer case. Once it's apart and laid on the table it looks like a lot but it really isn't.

    Where did you get the snap ring pliers at? I have the traditional sets for rings with the holes but I do not have a set with the flathead and grip like you used.

    Lmbo everytime you said flip it over or flip it around i kept finding myself leaning and flipping my phone trying to help ya i guess so yeah i guess your video must have been pretty good and very indulging and entertaining too 😂🤣😂👍🏼👍🏼 great detail and its really strange that you pump assembly wasnt bolted on like most are usually that pump has 4-5 bolts holing it in place

    Around your 3:00 mark, that little case you are taking off.... what "could" be a cause of a 2-3" crack near one of the bolt holes? Aluminum fatigue from the pump ears that rest against it?

    Good video sir! Glad this video is a "cleaner" one as I'm the original steward / owner of a 2003 Jeep TJ 4.0L w/ 5-speed here in Alaska. Gonna do the SYE + new rear CV driveshaft as it needs that SYE b-a-d as the TJ at 60mph here vibrates like a cheesy Las Vegas bed that uses quarter dollars to spice things up w/ the misses

    I didn't have a lock ring on the front output shaft when I did my sye kit. It's on a 2000xj np231. The shaft came right out together. Is the lock ring your talking about the one for the bearing? Coz my bearing has a lil bit of play and I don't wanna pull it all apart again if I don't don't have to lol

And in the year since I posted that question, I've learned that yes they can be, but I also learned that the NP236 was an easier swap for my Astro van. 😁 Cheers!
