In this video, Matt from BleepinJeep will show you how to install a Rough Country SYE or Slip Yoke Eliminator on the NP 231 Transfer case. I've done my best to make this a comprehensive guide with every possible scenario you might encounter while installing an SYE. This happens to be an NP231 transfer case from a Jeep Cherokee but should be the similar if not the same for Jeep Wranglers like the YJ, TJ, and JK or any other vehicle with a NP or New Process Transfer Case, although I'm not sure exactly how the NP242 differs. I hope this helps you on your install! Remember that the point of an SYE is to eliminate the slip yoke style driveshaft and therefore you will also need to purchase a new correct length double cardan driveshaft to install after the SYE.

Finally installed an SYE and Adam's driveshaft in my 91XJ. This video made me much more confident in being able to do the job. I did it with the transfer case in the Jeep. I have a 3" lift and 30" tires, and it was no problem getting underneath the Jeep to work on it (I'm a big guy). I had no issued doing the install with the transfer case still in the car. I'd do it that way again for sure. And talk about SMOOTH!!! All the vibes are gone, no clunks, just awesome smoothness. This was well worth doing. Thanks again for the video, BJ!

Matt, thanks so much for this video, made doing this job on the TJ a breeze. I was tempted initially to do a hack and tap, but this is really the way to do the job. On the 98 TJ 231 that I had, I didn't have the needle bearings (as you suggest in the video it's a pre-98 thing). For others thinking about doing this, definitely dropping the transfer case is the right answer. The only change that I would make from Matt's directions is to disconnect the transfer case lever from the transfer case (using the nut as opposed to pushing the rod through the linkage. Also, I believe that the rubber spacer goes under the yoke, not over it. Once again great job with this video!

Dude why would you swap a 231 for a 242?! The 242 is so much better because of all the options it gives you. Don't get me wrong the 231 is solid like the 242 but with less options. Most people want a 242 instead of a 232

Just a note: When seating bearings it's always better to start/drive it in with something that surrounds to bearing case (they sell bearing/seal installer kits). If you absolutely have to do it with the "tap and spin" method, use a brass/bronze bar as it is a lot softer than the bearing housing. Great vid! 👍

as long as you don't have locking hubs the transfer case will always spin at the same or close to the same rate as the main shaft.
