Let me know if that link stops working
My jeep was making a horrendous clicking noise every time I would let off the gas and coast while in gear. (You can hear the noise toward the beginning of the video when i twist the front drive shaft.)
I managed to fix the problem for about 60 bucks and about 12 hours of my time. Totally worth it. And with this video, anyone else will be able to do the same thing. Let me know if you have any questions. I respond pretty quick.

lol, it was one of my first videos... cut me some slack..
Its a fun project man. I'll take some time and frustration, but once you get it all put back together and working its the best feeling ever.
Thanks! It was a lot of fun working on it. And extremely satisfying when it all worked again. Good luck man!

The Transfer case would be very very similar. Get it diagnosed at a repair place first. Sometimes they do it for free. It would be annoying to pull the T-case apart and find out it is working just fine.
You guy's did a great job! Really proud of you for taking on that kind of project and seeing it through!
@Ian Chapman it was a 93. good luck man. its quite the fun project. let me know if you have questions.
If i remember right it was part of the pump system. But its been about a year since i took mine apart.
Thanks! It was fun. Gave me something to work on for a week. I enjoyed it.
if i saw a jeep to buy with that mess on the transfer case, i would run away from it fast
Agreed. I had to take it apart 3 more times before i realized my bearing on the output was sticking out a mm too far. So i had to re seal it every time I put it back together. Thats why it looks like i used so much.
Am I the only one who's noticing a voice change?
I don't quite remember but i think it was 30mm. I made a video for how to change out the fluid. If you search "NP 231 J Transfer case flud change jeep" It should pop up.
Informative video, good tip on shifting into 4wd to move the output shaft high enough up to get the snap ring back on. Just an FYI to anyone else doing this job spend the $12 at NAPA Auoparts for the snap ring pliers, this'll save you a lot of time and aggravation.
I just finished putting mine back together, those plastic pads were worn off on the Big Fork (mode fork?) inside my case not letting 4x4 fully engage. Hopefully it's fixed now.
JEEEEZE how to do it wrong - support the transmission! Remove drive shafts first....gha Factory service manual is free online.
All I got to say is good job man. That takes balls never getting into a job like that. And in the end it worked. Good job
That was extremely well done. Nice work guys. Have a 95 that has a cracked (shattered) case. Looks like its gonna be some doing! Thanks.
Just giving you a hard time man. Had to. Haha. Thanks for putting it up. I dropped mine last night and the vid gave me an idea of what I was in for.
good video man looks like im gonna be doing some of this myself
lol, no, that was pretty easy actually, compared to the rest of the project. Just make sure to have something to support it when you are ready to take it off. Little guy is heavy.
On my 03 TJ the skid plate is the mounting bracket, but otherwise the same.
Great job for not sitting on the couch. Please, look to the right and check out some of the T. C. videos by folks who do it everyday. Not using "um" to much is a great start. Looking forward to the remake, (Why not to use so much silicon) where "this part" is replaced with words like pump, output shaft, yolk... Keep up the good work, DIY forever.
Did you use enough RTV? The proper way to use RTV is to apply a bead behind the bolt holes and then compression will flatten it out without it getting in the threaded holes.
Great vid guys! Lots of good info
Hello from Mexico, friend, in your reconstruction, did you see in which part of the transfer the speedometer cable connection is located?
Thanks for the upload bro. The 5:27 sound was the wife calling to make sure you weren’t doing the repair job on kitchen counter. Been there. What did the apartment complex say about any asphalt stains? Im about ready to start mine.
Looking at doing the same thing. What year was the YJ? Thanks for the post
My universal joints snapped & my rear driveshaft broke off the transfer case & the male end that comes out of the transfer case is crooked. What parts and where do you suggest to get the parts? 🙏🏻
Heh, I found this vid about a year ago just wondering what it would take to crack into my t-case. Low and behold, my jeep started making the exact same noise not too long ago, and I yanked the t-case and cracked it open today. Yup, the shift range fork is worn out and I'll be putting a new one in as soon as I get it. Thanks for the vid, it made my life much easier.
Super glad I could help! You just saved yourself a huge chunk of cash by doing it yourself. TH-cam rocks.
JerryRigEverything I just bought a 95 grand Cherokee v8 with the same problem. Suspected tc and man I'm glad I found your video. Saves me a ton of time and cash. Thanks for the knowledge. My wife will be glad to have it going. Only paid 700 for it so its a deal
700 is way good! Good luck with the project!
how much different would this be on the 2001 grand Cherokee I kind of have the same problem but it would make a loud click noise every few seconds while driving at low speeds
QUESTION! @ 5:00 exactly you can see the output bearing after taking off the first guard cone. After you remove that snap ring can you somehow pull that bearing out without taking off the whole second base?
You have to split the case to R&R the output shaft bearing.
Crazy, this is before all the phone testing.
i have a 94 cherokee sport that has had the chain sliping and jumping around. i bought a rebuild kit for it... have any advice?
is the tube in the t-case the breather vent?
Hey Jerry... nice video - got a question.... when you installed the TC back onto the tranny.... you mention a little seal thingy.... I have mine out currently and putting a SYE on it... when i go to install i back into the jeep... is there a seal or something that goes in between the tranny and TC? I am assuming no RTV between there....
If you haven't got your answer yet Kevin Bartoletta the TC and tranny are completely separate from each other..meaning they do NOT share fluid. No seal needed there.
DId you get the 31 or 36 link chain?
My YJ will not work in 2WD but in 4WD. I assume TC is my issue. would you agree? and hopefully its the chain.
My son in law ran my jeep off the road in 4wd the other day. Since then it wont run when we shift it into 2wd and is making a horrible loud noise. We managed to get it into 2wd twice but it wont drive reverse or go into park and can only be run in 4wd. I think its the transfer case but not sure what part of the transfer case it could be. Do you think it is most likely the Tcase or possibly the transmission?
It's most likely the t case. I just did the same thing with my yj. Turns out that I just snapped the slip yoke on my car so I decided to put on a new SYE on it. Just get under it and check the driveshaft and slip yoke assembly. Something probably broke there
lol, come on bud, it was one of my first videos. Cut me some slack...
you dont need that much sealent man
Not the drain plug!! that’s the detent cap don’t unscrew that it’ll drop out the spring and bullet! The drain plug is on the rear case half
Wait no bend test? or burn test? :)
Where was the step by step rebuild part? All I saw was a poorly done R&R of the T-case.
ya man , nice vid
how long did it take you to rebuild the transfer case altogether?
+Cody Blizzard Now that I know what the problem was... I could repeat the whole process in about 4 hours. But this video took probably 8 to 10... It was my first time inside the case.
Man, you shoulda put an SYE while you had it out anyway!
tobster421 I should have! I just wasnt sure if I was going to be able to even fix the issue at the time I removed it.
What was the part called that was ground down?
Shift fork
You're going to need more sealant than that. The stuff should be oozing out a lot further than that. Like drooping down like ice sickles. That way your oil pickup tube can suck up any excess inside the t-case plugging oil passages and detonating it all over the road leaving you stranded. Other than that good job.
I like the way you think.
Will this be the same for a 1994 jeep wrangler yj.
It would be pretty much the same.
I see that you replaced your shift fork. What kind of problems were you having before this repair?
When I would let off the gas and coast, It would make a horrible grinding noise. I kind of show what that noise sounds like in the first part of the video when I twist the drive shaft back and fourth under the Jeep.
JerryRigEverything My TC have been making this noise in the last several months...only happens between 10 mph and 40 mph
Do you know the size of the fill/drain plug on the transfer case?
Im using a 30mm 12pt...
Hey I have this np 231 J on my 2003 Liberty sport.....t-case has 225,000 orig. miles on it and fluids have always been changed at recommended intervals.....also never abused the t-case.....makes a low speed growling noise now. ??? What could that be?
Its hard to say over the internet.... its it making that same clicking noise that I showed in the video?
Most likely a bearing going.
Thank you
No problem! Glad I could help!
Damn ipad. I am replacing my transfer case after it grenaded... Was it a bitch to reach all 6 bolts holding the trans to transfer case?
that little tube is connected to the oil pump
your voice hasn't changed one bit
I try to say 'Um' a little less in my videos now ;-)
JerryRigEverything haha that's true 😂
Who's watching in 2021
Wow
Hey man good video. I am do
Counted 67 "umm"s up to the 7 minute mark... I had enough of "umm"s for a whole year
+Alberto Cabada lol, I think there is like 130 or so in the whole video. I went back and counted once too. Luckily.... I improved a little with my 'speaking on camera' abilities over the years.
bro can you attach a AX15 to a NP231
Yes
Hey man
Where are the vacuum lines on it
On the stupid plug...
Salut cassy
All that silicone will inevitably end up plugging the suction off your oil pump and...umm.... ruin your transfer case
jeep makes phones?
Holy Olddddd and that fact you were calling the c clips "orings" LMAO
Ummmm
+Duran Sexton I only say it like 170 times in 15 minutes. Chill out bro.
*only
+JerryRigEverything Meanwhile most people say it 500 times in 15 minutes.
