Install a SYE in a Jeep XJ the easy way/NP231 upgrades with Adams Driveshaft for XJ, TJ & MJ
Вставка
- Опубліковано 5 вер 2024
- Some Guy takes on his first real driveline project with installing the Rough Trail SYE to fit a brand new Adams Driveshaft in the rear end of his Jeep Cherokee XJ. The NP231 transfer case was installed in a range of jeep vehicles such as the XJ, TJ and MJ for decades.
You'll need at-least one car jack, a standard range of wrenches, 2 quarts of ATF 4, RTV gasket maker and a torque stick capable of 150 foot pounds to install this kit.
I bought this kit with my own money, no sponsored products.

Great video! The trick with mapping out all the bolts is really smart. We all do it, we start yanking out bolts and we think we're going to remember which ones went where, but then we don't remember. I agree with your assessment of comparative difficulty too. I would be easier to do the SYE install on a bench but there's the added effort of removing the transfer case. As long as you can fit underneath your jeep without any problems it is totally doable to install the SYE in the vehicle. Keep up the good content.
Very well made video, really enjoyed it. As someone planning on buying/building my 1st Cherokee this year, I've been watching tons of UA-cam videos. However there was one thing that stood out to me in your video, and that was the amount of RTV you used in resealing your TC. I own an 05 GMC 2500HD 4x4 with one of the common New Venture TC's that are known for the pump wearing a hole in the rear case half.Mine doesn't leak yet, but they all will eventually unless you put the proper upgrade part in them. My TC also won't shift into 4lo (grinds) unless you turn the engine off. Planning on pulling it and addressing these issues this year. So I've also watched several "Precision Transmission" videos addressing the leak/hole issue. The one thing "Richard" (God) always stresses is not over using the RTV when resealing your case halves. He has shown countless examples of how the excess RTV that squishes out inside the case ends up in the bottom of your TC and ends up clogging up the screen on the pickup tube, obviously leading to starving your pump of ATF and shortening the life of the TC. I'm sure many of you are already familiar with Precision Transmissions channel. If not check it out and prepare yourself to be educated by an experienced mechanic and drag racer!
Not trying to be a "know it all", just thought it was some very worthy info to share!
This is an interesting repair, with super tips as to dismantle and assembly. Exactly why I think it's very useful is that owners of the XJ like myself, come to love various quality as to the handle character of the 4x4 and quite all of the cargo and functional passenger domain.
Various major drive train work, which can include repair and replacement to transmission, should include a truly long look at the torque converter (and starter ring) at disassembly. That output plate, a clock bolt configure of only one correct mounting. Absolutely use top quality seals, correctly installed and where useful, pre order new bolts. The realm of hi mileage at the rear main seal, and all further rear drive components require particular care in both assembly and fitment to prevent the dreaded Jeep oil spots to drive way. The torque converter alignment and wear to the transmission front seal, as where a wear grove can be very slight but difficult as to cause a constant leak. Another difficult leak component just forward, is the oil filter mounting o ring. A problem to remove as very tight clearance with a hex recess drive to the center mount fastener. If available to replace that o-ring, a must for longer term slight oil leak avoidance.
For the serious minded XJ owner, where the exhaust is so fitted to unmount with bolted weldment, as to a joint, is a huge asset to remove any of the driveline and transfer case, transmission. *and or motor pull.
Not mentioned, but a truly nice mod is replacement of the power steering bracket and device to upgraded aftermarket replacement. And, entire further mods are at hand.
These units can still be found and converted to nice project units at a fair price. Fair trails to owners. M.
Young man, awesome video. Great explanation for all the steps. Thank you for sharing!!
I know this is an old video and I’m sure you figured it out already but there is a snap ring tool designed specifically for that style of snap ring that would have saved you a lot of time.
I also have a 95 jeep cherokee xj and i put a 3.5inch, and I love my jeep.
They’re such capable vehicles with so little modification required for most the fun you can find!
Fantastic Vid! Just received my Adams driveshatft and Teraflex SYE kit and getting ready to tackle the exact same setup this weekend. Decided to see if I could find some help. Watched 4 videos and this was by far the best detailed explanation. I was terrified of pulling the entire TC but this gave me the perfect alternative. Never did see the link for the shifter though. THANKS!
I’ve got a separate video on upgrading the shifter linkage, I’ll go in and link the videos for the future!
I installed the Azzys on my 93 xj with 231, and it’s made huge difference. This is first I’ve heard of SYE benefiting street/hwy driving (my xj is daily driver), so I may look into it now. Thank you.
This was a huge help!! I'll be watching this again a few times plus one more time when I finally change mine out
Great video, man! Excellent quality. Keep cranking out content as you can!
Thank you!! I aim for a video every Monday or two, most my free time I put towards working on projects or going on adventures the hardest part is finding time to do the editing for all this! I really appreciate the support, I’ll tryb
@@SomeGuyOutside Heck yeah! Off to watch your headliner video now! Have a good one!
I did an Advance Adapters SYE on one of my XJ's. I know you can do it in the rig but I found it easier to just pull the T-case and do it on the bench. T-case comes out in about 30 or 40 minutes. Best thing you can do is get rid of those damn t-case drops. I am in Washington as well, don't see many people on here from Wa.
Hello fellow washingtonian. I put the TCase drops in a few years ago to help prevent the eating of Ujoints the stock set up was doing to me and they are GONEZO now. Id seen a bunch of videos of people taking it out and as a mostly self taught home mechanic I certainly felt some hesitancy towards doing it. I didnt see many videos on doing it in the vehicle and figured theres probably other people who would feel more comfortable attempting it their first time the same way 😂.
@@SomeGuyOutside It's done and in that's the part that counts, see you in the dirt
Use a flat/offset snap ring pliers set, it work so much better.
The XJ's crossmember definitely makes this an easier job to do under the vehicle. The TJ's skid plate covers the whole thing up from underneath so it's a much bigger PITA. Wish the TJ had a cross member and separate skid.
Thanks for the video. Just about to do mine. Waitng on the SYE to arrive today. Am I missing something? Other than to remove the transfer case drop wedges, I see absolutely no reason to remove my crossmember. Doesn't look like it will interfere with the rear case removal or anything else. Explaination? 2001 XJ
I know this is a necropost, but you mention the snaprings a lot. There is a different tool for bare-ended snap rings that makes that quite a bit easier.
I have since learned, thats life though. Got the test before the lesson.
Nice video! Hopefully I’ll use this in the future after I lift my XJ down the road
I waited about four years after I lifted mine to do it and I would recommend prioritizing it a bit more than I did 😂 thank you!
No one's been "Lied" to about removing the transfer case for the SYE install. I think this video illustrates why it easiers with greater success doing this install out of the vehicle. Try it installed, and when you realize cleaning and re sealing the case halves in car and not having a leak afterword is unlikely. Then you can do it again with the TC out of the vehicle successfully.Take for instance the 3 hours spent removing/installing the output shaft c clip, a task out of the vehicle would take less than a minute each with the proper tool. Multiply this extra time for the difficulty lying on your back performing all the steps involved and your better off spending some of that time simply removing the TC in the first place. If your experienced with numerous SYE installs, you may save time and have a leak free install in car, otherwise I'd pull the TC out and do the install comfortably on your work bench.
I agree, pulling the transfer case wouldn't be worth it. The work you have to do on the t-case under the vehicle is much easier than accessing the 6 bolts that holds the t-case in. Thanks for calling out to put the oil pump and pick up together first. Great video.
Thank you! It’s definitely a job that can be done from ⬇️
Excellent Video! Thank you. I think i'll drill holes in the snap rings myself to make the job less stressful.
I’m not sure you’d be able to do that with them installed but after maybe 🤔? My only worry would be that it would compromise the strength of ring material and if it breaks you’d have a couple tiny chunks of metal flying around your transfer case. Worst case scenario, just trying to be the devils advocate not saying don’t do it!
Why not just buy a couple correct size c clips with holes??
That much sealant will plug your oiling system
Good video this will save time, just my two cents bud.....they do sell snap ring pliers that have wider tips , the ones you have on the video are just designed for the ones that have holes....regardless you made it happen...well done
The first pair I bought had a bit wider tips but didn’t spread wide enough. The second pair spread wider but had the rounded tips. I think my third pair will be the perfect fit!
Did mind under the XJ. But bought all the snap ring pliers It wasn’t fun or bad with all the tools needed
You forgot to shim your rear axle to get the proper pinion angle.
I think you would really enjoy a better set of snap ring pliers. I took apart a np231 to make a crawl box and I've rebuild a np435 transmission they both have that kind of snap ring and the cheap snap rings pliers are like death for removing them. The snap rings are like that for a reason and it is because they rotate with the shaft and as such the tabs coming up for the holes like the traditional snap ring have will cause problems by being out of balance and in really high rpm situations could cause the snap ring to come off the shaft and really give you some problems.
Yeah so I originally bought a pair of snap rings listed as 2 1/2” spread with like four different heads but they only really spread to about 1 7/8” and the nose/teeth material we’re not close to quality enough. The second pair I got did spread wider but I still felt like they could be better. Definitely looking for a better pair. Good to know on the snap rings aswell! Thank you
@@SomeGuyOutside LOL @ "Remember to try and remember everything." Yeah, the "duck bill" style lock ring pliers are the way to go with those stubborn SOB's! Thanks for the vid...nice refresher for the long overdue re-sealing of my t-case. It's been weeping fluid for the 5 yrs since my JB SSSYE install on my TJ (did the install under the Jeep and...outside)!Gonna give Yamabond 4 liquid gasket maker a try this time
Awesome video
Thank ya!
Is that not an np242? That looks like the exact same Tcase as mine and mine is a 242. I guess they could be different in other ways but still
It's a lock ring, not a snap ring. Different tool. Hope it save some of ya'll some time.
Хорошая работа 👍
You try to give the video more brightness it will be great if you do
Since making this video I have gotten some magnetic stick lights, definitely still working on improving some of those qualities of the videos. thank you for the suggestion I do appreciate it!
Would have drilled my own holes in the snap ring
Have learned the difference in various snap ring tools since this project!
Yeah, good luck with that. Those rings are hardened steel. You don't just grab a drill and punch a little hole. Plus those rings are purposely designed like that and using the correct " flat nosed " ring pliers makes installing and removing them a cinch.
Dude...Great video...But you are using the wrong pliers for that style of snap ring...get the right tool and installing them will be a breeze.
Great video, I have the Azzys Design for my transfer case. I have to put a SYE in my 2000 Cherokee which has a 4.5” lift and is eating u joints. Will the Azzy Design still work with that much lift? How much lift and what size tire are you running? Your Cherokee looks great and your videos are awesome.
Thank you!! I absolutely think it will help/work with that lift. I am about 5 inches in the front and 4 in the rear with the sag of my leafs over the years I think and it has worked wonderfully the last six moths. Ive got BFG ko2 33x12.5r15 on and they're about four years old and have at-least 20k miles on them and have a bunch of tread left, run amazing in the snow and dirt but are starting to get a bit of wobble and bounce in them.
Not spout, pickup tube.
I'd recommend safety glasses when working under a Jeep. Getting rust, dirt, or oil in your eye can ruin your day... or worse
That it certainly can!
nice👍🏼Ninja！
Good job! I would never attempt this on the ground (at my age) but I have plans on doing this to my 95 XJ. Will probably do this job on a lift. What adjustable control arms did you use on your XJ? Can you post a link? Also where did you get your new rear driveshaft and cost? Thanks for your time. God bless and stay well.
I didn’t love doing it at MY age as I’m without a good dolly, sometbing I like would make a job like this waaaay easier. I got the shaft and SYE kit from adams driveshaft in one of their holiday bundles. The bundle was about $400, certainly steep but I wanted quality and American made parts and I haven’t been disappointed in the many months since!
Oh and the control arms are from Core4x4 ! I would recommend them, straight beef. I want to do their long arm kit one day but like all quality American made parts, takes me some time to save up
I’d like to do this upgrade but it’s very expensive here in Australia :/
It wasn’t cheap here but I’m sure the shipping alone would be tremendous! There’s a whole bunch of stuff you aussies build that is expensive/impossible to get here in America so it’s always greener on the other side!
@@SomeGuyOutside we always want what we can’t have, lol.
You don’t need to remove crossmember
Need to remove no, but it’s only removing eight more bolts and it gets you a good a bit more ease of access to everything. seemed worth it to me
Great video, great work! How long did this project take for you to complete? How high is your jeep lifted and what size tires are you running?! Cheers!
Okay, you answered my first question already.. lol. Definitely still curious to know what your lift/tire combo is!
@@ryanellis5902 no worries! I’m planning a follow up video with lessons learned stuff. My Jeeps about 5 and a smidge inches between a 3 inch leaf pack in the rear with 2 inch shackles and 4 inch cheap coil with two inch pucks. I NEED new shocks just have some junker rough country ones atm. BFG 33 X12.5 R15 are my current tires, overall I’m happy with them. They do WONDERFUL in the snow, never had or seen an open diff do as well or better in the snow. Certainly some road noise and vibrations that come with them on the stock axles. Oh and I swapped a Chrysler 8.25 rear axle out of a liberty or patriot in a junkyard!
@some guy outside Thanks for the info! I wanna lift my xj 3 inches to fit 31x10.5R15s (which I already have) but I can't decide exactly what lift to get.. its either gonna be Skyjacker or RC. Rough Country will save me some $$ but I don't want cheap parts either..
I'm also wondering if I'll get any driveline vibrations from only a 3 inch lift.. but only time will tell there.. any suggestions would be greatly appreciated!
@@ryanellis5902 well rough country is a good start, my first lift on this jeep (only jeep I’ve ever had) was full rough country and one by one I replaced them all except the shocks 😂 it’s certainly paying for what you get rough country will get the job done but not much more than that. I was at 5 inches of lift and it wasn’t tell a small tiny little bitty jumping of my Jeep that i messed up the driveline and started to get vibrations. I lived with it for like two years after that, annoying but doable. Much better without though 😂
Where did you get the work table I need one of those. 👍
If you're referring to the black one its a black and decker from Lowes, I think my mom got it for me for christmas when I was pretty young and had just started getting into woodworking! Its served me great for over a decade now.
Where did you get that little work table
its a stanley folding sawhorse. It was from home depot or lowes I think. Its very handy
Where did you get it at
That was a Adams Drive Offroad set from their websites
Are you sposta put fluid in the SYE?
What? I don’t quite understand your question.
Make sure to adjust pinion angles or you’ll be buying a new transfer case, possibly a new trans.
Certainly an important aspect with plenty of quality videos out there covering it!
