- In this video I will show you how to install a SYE (Slip Yoke Eliminator) in a Jeep np231 transfer case. I will be installing on a 2001Jeep Cherokee XJ. This process is similar to nearly all vehicles with the np231 transfer case. If you have any other questions that the video doesn't cover make sure to comment below and I would be happy to answer.

Such a great video. I watched it a few times before removing my transfer case. I have my case out now and you had me prepared for everything and I made very quick work of it
Just installed an Advanced Adapters SYE kit and your video made it a ton easier. Thanks for the video.
My bro your videos are awesome .I was going to have my SYE done but now I'm going to do it myself after watching this . Thanks man keep the jeep xj videos coming .
Nice, clean and descriptive video…thanks!
It was a great informative video and I really appreciate it. I’m going to be doing it on my 97 shortly thank you
loved this video man. very detailed. im going to need to do this to my tj
Good job man..thanks for sharing!!👍
Nice tutorial 👍good job👍
Liked and subscribed. Thanks for the great videos
Good video, as always. Just make sure that your ATF is compatible with Dexron III, as this is what you should use for this transfer case.
Great install guide made it look easy. Well except for the snapped bolts lol
You have skill as a presenter or trainer. good job
Nice video. I need to do a SYE. My 1999 Jeep Xj has almost 350,000 miles and is just like new...These Jeep's run forever.
I have a stock 01 limited with 31000 green 4x4 mint
Great video again! Nice work Austin. I will do the transfer case drop first and then this SYE later. I'm hoping the vibration will stop since I just did the 3 inch lift. Eventually I will get to the SYE for the long term
I installed this SYE back in 2006 on my 2005 wrangler unlimited a few months after I installed a 3-1/2" RE lift. Still working awesome after 66k miles.
If I install a SYE kit do I need a different drive shaft?
@@davidchavarria I did have to install a longer driveshaft. might not have to in all cases but I wanted to guarantee there was enough movement in the driveshaft with no binding.
Excellent job, thanks
Note; your gears may have needle bearings inside them on older transfer cases. No big deal, all you need to do is press them out before sliding them on to the shaft. Also want to clean off the magnet and clean the filter on the fluid pickup before reinstalling the cover. Very clear instructions, nice job!! RC has a vid covering the removal of the needle bearings and checking the shaft bearings wile it's open (older high mileage cases especially). You are providing great content, Really like your channel. Keep it up!!👍👍
You are correct, older model np231 cases had needle bearings. This was newer so it did not have them.
Brave man to do that...
Nice job....
Do you need to take off the transmission mount and exhaust hanger? I don't think either of them actually attach to the transfer case.
How to adjust the shifter fork someone installed the kit but didn't adjust shifter fork it will adjust with the yoke on back off but now wont
Great Austin
Great job on the video no horsin around straight to the point, 1 question there is suppose to be a magnet that goes into a slot on the case and i didnt see yours ?????
Yup there should be a washer shaped magnet in there.
What is that plug with the white (plastic)gasket ? Might be a dumb question I am just trying to learn. I’m leaking and I’m not sure if it’s from there or from above it and just running down to that plug
should have used anaerobic sealant, it dries without the presence of air, and makes a tight seal, mopar recommended for trans and transfer case halves
Do i need a new driveshaft for 3.5 lift too??
I attempted to pull the Tcase yesterday and had no luck getting access to the Tcase nuts on the passenger side thanks to the exhaust.
Did you use a very small tool to break them loose? Do I have to remove, aka cut the exhaust off in order to get a standard wrench in there to remove the nuts?
Great vid, is there any limitation to using the front shaft? I have a 2001 chrisler 8.25 in the rear. Its lifted 3.5 inches.
I have been running my Jeep like that for 3 years so far as a daily driver with no issues.
Great video I do have a question does it matter what year or model cherokee you use the front driveshaft from ?
It all depends on the drive train you got, this may help: www.naxja.org/forum/showthread.php?t=1118885
Great video!
get you some PB Blaster bro. Works wonders on those stuck bolts. Better than WD-40 when it comes to braking bolts loose.
Gator Schopper
Kroil's even better than PB blaster and it smells better 👍
50/50 mix of acetone and ATF. Just make sure you use an acetone safe container.
That stuff does in minutes what PB Blaster takes hours to do.
Good Job 👍🏻 XJs Rule 👍🏻💯%🇦🇺⛽️.
This is a great video to follow along with. My only comment would be to let the RTV dry for about 5 mins before fully torquing the bolts down. That way you don't get as much pump out as seen in the video. Also, make sure to actually go 360* around lubed surfaces rather than 180*. Other than that, someone could easily use this video (and a spare set of hands) to swap the SYE out.
Cara vc usa muito silicone , isso solta dentro e entope a circulação do óleo e rolamentos. pense nisso
I helped.
Great video! Thanks for sharing. I put in a Zone 4.5 inch lift kit with the full leaf spring and shackle package. Did your vibration go away? Maybe you did not have any after you installed the lift and drop. My setup vibrates a bit even with the crossmember drop in it. How about your pinion angles front and rear? Did you have to change that to accommodate the CV driveshafts? I was thinking about putting the old front CV driveshaft on the rear to see how it fit then have a local driveshaft shop build me a set. I do appreciate your videos. I think you are (please don't take this wrong) a guy that is on a budget like myself that isn't given parts for free like some of these YT superstars get on a regular basis. You might become a YT superstar though if you keep doing what you are doing. I haven't found a video of yours I haven't liked.
Thanks! I haven't had any vibs really with the rear with the drop and SYE but rather the front shaft I have. The front has an even worse angle with a drop and wears the slip joint of the shaft out pretty fast. So I really wanted to get the SYE done to fix my front shaft vibs. I haven't even measured the rear angles at all but it ain't terrible, maybe later on ill shim it but its not causeing any vibs at the moment.
@@OutJeeping I did order the AA SYE from Summit and two driveshafts from Adam's Driveshaft and Offroad. We'll see what happens. Funny thing happened to me at a chain parts store today. A guy came up to me and said he really liked my XJ. He had lifted a commander with a Hemi and had a hard time finding rims to fit it. I thought it was unusual to pick a Commander to lift but I did like the idea of a Hemi though.
@@1crazynordlander Nice, I do like those commanders for that reason but they are harder to lift than Cherokees.
What size socket is the 12 point that is needed on top of the TC? Mine isn't the same size as all the others.
I believe its a 10mm
Im going to do my SYE, have you attempted doing this since or before without removing the Tcase and simply rebuilding in the tunnel? would you recommend or not?
I have on one of my friends jeeps and it is not as bad as it sounds. It goes a little bit faster but the disadvantage is that you are working all the time above your head.
question, did you put a new chain and seals and bearings since its apart?
I put in a new fluid filter. Everything else was in good shape, wasn't planning on a full rebuild.
I have a 6.5 inch lift. Would the front drive shaft fit the rear with this SYE?
For a 4.0 with auto trans it should fit, that's what i did to my jeep.
How did you get to the 2 driver side bolts and the bottom passenger side bolt when removing the transfer case? I cant seem to get even a miniature wrench on any of those :(
Small wrench, maybe drop it a little lower.
How where you able to get the snap ring onto the new shaft ?? It seems impossible
A tool like this would help: www.amazon.com/gp/product/B003UHUCQM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
What size socket are you using at 9:11 when removing the nut connecting the front axle yoke on the transfer case?
I think a 1-1/8" but I could be wrong.
So you used a the front drive shaft for the rear drive shaft?
FishRVA Yup, works in a pinch
awesome vid man, was that front drive shaft that you used to hook up to the SYE stock? wondering if i can just grab one from a junkyard instead of dropping another $200
Any front driveshaft from a Cherokee XJ auto will fit for the rear of a Cherokee with a SYE.
OutJeeping thanks man. I stopped by a 4x4 shop and asked the same question after I watched your video and they were convinced that I needed to have a custom shaft built for $600. Eff dat! 😄
Yeah I've been running the front shaft for 5 months so far with no issues. I may eventually get a Tom Woods or Adams driveshaft which only costs around $250.
@@OutJeeping this will be good for a 4-4´5 inch lift?
@@lagulagunation Yes, its recommended for anything over 3" of lift
Once everything is disconnected from the t-Case, obviously you lower it to get to the bolts right? How much did you lower it?
Just low enough to get my hand up there to get the bolts out. Any lower will put too much stress on the motor mounts.
Did you say you can use a front drive shaft for the rear??
On the Jeep Xj with auto trans and 4.0 you can
Faare GooooD
Did you use shims to angle rear diff to the t case? If so what degree and what size lift are you running?
Phillip Wagner I didnt have to on my jeep. It doesn't point directly at the t case but there is also no vibrations so I'm going to let it be. But on my buddy's old jeep that had a 6 inch lift he had to put 2 or 3 degree shims in his axle.
I'm running a 4.5" lift. 3.5 leafs with l inch shackles.
@OutJeeping is it the same for a manual cherokee?
Should be the same process if it has the NP231 Transfer Case.
What was the yoke you selected when you bought the slip yoke eliminator
I opted for the 1310 U-joint Yoke.
did you have to cut the shift rod down in orger for this to work?
I didn't have to but older transfer cases requires it.
How much older? I have a 95 XJ I'll be putting this kit on if it ever gets delivered. Good video!
I noticed that you never used any liquid wrench or wd-40 when trying to break free your old rusted nuts and bolts. Also no lube when putting the muffler bracket on the pin.
Sometimes I go in dry and sometimes I use some lube, depends on my mood.
When you ordered the advanced adapters she kit you mentioned you were gonna run a front shaft in the rear what yoke did you get with the kit to run that shaft
I'm running the standard 1310 yoke on mine, fits the factory front shaft and alot of after market option rear shafts.
@@OutJeeping is that the 1310 cv or non cv
Is the standard non cv
@@mattcannon1231 Yup 1310 cv joint, here is the link where I got mine. www.advanceadapters.com/products/np231-sye--new-process-231j-fixed-yoke-kit-50-7906--50-7907/
@@OutJeeping thanks
My front driveshaft is a bit short when I put it in the rear, it doesn't fit. I have 3 inch lift only. @OutJeeping I have 1999 xj. Any idea why it's a bit short?
Also I forgot to prelube the transfer case gears, will that be a problem?
Do you have an automatic transmission with the 4.0? If not different drive train combinations will have different driveshaft lengths. As long as there is fluid in the transfer case before you run the jeep you should be good.
@@OutJeeping thanks for replying. My jeep is a manual 4.0
Would it hurt if i left the transfer drop that came with my lift when i install the sye
Driveshaft angles would not be ideal because you have to change the rear shaft to a double cardon shaft. The angle specs between the 2 shafts is different.
@@OutJeeping any differences between a 95 231 and 99 231 both automatic
At this point why don't we replace the chain like a timing chain and new o ring in that pump tube
You could do that, mine all looked in decent shape but I did replace the filter.
what size bolts did you use? Did you use a washer & lock washer too?
What bolts are you referring to?
@@OutJeeping the crossmember bolts
Which yoke option did you go with
1310
What does installing one of these achieve
I explain in the beginning of this video: th-cam.com/video/cFd_MDUljG0/w-d-xo.html
What dose this do? Why change? Good video...
I explain more of the purpose of an SYE in this video:th-cam.com/video/cFd_MDUljG0/w-d-xo.html
What kit did you use?
Advance Adapters
Is it just me or does it seem like it’s smarter to pull the driveshafts before anything else? If I have to spin the shafts to get to any of the bolts, I sure as hell wouldnt want to be jacking anything up to clear a wheel while that transmission is only supported by a piece of wood on a floor jack.
That can be done before hand. But it is easier to access the bolts for the front shaft at the t-case end when the cross member is removed.
So what goes between the transfer case and transmission?? Rtv or a gasket?
From factory there is nothing, in the video i did rtv in case the rear seal of trans were to go out, there would be an extra seal there but later on i had it pointed out that there is a weep hole in between the 2 so putting any seal there is actually useless. So don't bother putting anything there.
to install sye, you do not need to change the Driveshaft???
in the video it looks like an old driveshaft.
The the XJ with the 4.0 and auto trans you can get away with a front shaft on the rear.
OutJeeping any problems with using one?
Did you have to change the rear axle angle at all with shims? I put a 1inch and 1/4 drop on my transfer drop and it took all the vibration way but I still have a slight Growling noise when I decelerate.
On some applications you may have to but I didnt with my suspension setup where I have longer shackles so the angle of the axle points up more. But pinion angles vary from an SYE kit and a tcase drop
Would’ve been better if you gave the T case a good wash before you open it, just to make sure no dust, sand, debris falls inside the case
Can I do this to a 242j?
You can, only a handful of companies offer it for that t case, they happen to be more expensive too.
@@OutJeeping 😭 I'll just keep mine till it breaks
The "fun" begins at 7:23 folks.
What's the purpose of installing this kit?
I explain that in the beginning of this video: th-cam.com/video/cFd_MDUljG0/w-d-xo.html
Rtv on the splines ? Wtf you just poured atf all over it . How’s it going to seal ? I think it’s a bad idea but I could be wrong
Its sealing just fine, you normally just want to use ATF to prelube the inside components and the Yoke seals. Using RTV on the splines can be done if the kit did not come with rubber spline shape seals. Mine did come with the seals but unfortunately I found them after I assembled the case back together.
my 1/2 " torque only goes to 150
Just get it as tight as you can and you'll be good, its not like an axle where it has a crush sleeve to compress.
Autozone rents one
Be sure to lubricate your shaft before sliding in.
:D
Never go in dry
I beleave in Germany they call it vienner schliden.
So what problem is this fixing?
Driveshaft vibrations with a higher lift.
@@OutJeeping witch lift 3 inch or 4.5" lift will need this?or higher?
@@rafaf2815 I didn't have any vibrations with 4.5" of lift.
why didnt you clean it up i just dont understand.
The inside of the case was cleaned out before it was resealed.
the speedo gear does not have to be aligned, that is a myth. The sensor creates pulses, it has no orientation, it only creates pulses that are multiplied by a specific factor and create MPH.
Not with these older transfer cases, it is a physical gear on gear contact. But I know what you are talking about where the sensor reads pulses, that does not apply to this application.
@@OutJeeping It is a physical gear on gear that then transfers into pulses and out of it comes a wire. The wire has pulses, there is no other way around it, the wire has an electrical signal in the form of pulses.
Holy crap, thats a big job. I dont think I'm up for that :/
Not enough info for a beginner to do this right. When you break stuff, talk about what you did to fix it.
This videos purpose was just to show a slip yoke Eliminator install not a rebuild of every part of the transfer case in in case it were to break.
For the mount and exhaust bolts, are they prone to snapping or is that an issue in the rust belt? Not a whole lot of rust issues here in CO but idk the condition of mine
They are more prone to snapping for vehicles in the rust belt but all vehicles may vary.
@@OutJeeping Do you happen to know what size nuts to use for the Transmission mounts? I think I'll get new hardware along with a new mount.
It's the 2 bolts on each side of the mount i'm worried about as well.
