I think you're right. Might as well change the clutch if it's been a while. I had a bad experience with a crappy clutch kit and went in last month and replaced it all over. I used a LUK this time and also changed the flywheel with a LUK. Good so far.

Does the t-case come off separate to change the clutch or does it have to come off with the tranny?
I work alone,lol
I've done many clutches before just never on a 4wd and I can't find my Haynes manual

You can do it either way, it's only a couple more bolts to separate the TC from the trans and it's alot more manageable to do it alone without the case hanging on there.

I was reading a clutch replacement thread last night on here or jeep forum. I think it is an e12 and the transfer case is an e10. Jerry knows which one, he has a few threads talking about it here as well.

This was the write up I did, doesn't have as many pics as the other write up.

New Clutch Install/Writeup - JeepForum.com

E-12 torx for the upper bell housing bolts, can be found at NAPA. I then replaced the torx bolts with hex bolts since even with the e-12 socket it still buggers up the bolts.

my pilot bearing is pressed into a sleave and that sleave has about .070 thousands slack
is this normal?
the pilot bearing will fall out the crank so when I stab my tranny back on the bearing will fall,At this point I will try to get one tommorow if not I will shim this one

if the pilot falls out of the crank there is a reason for it (did itspin in the crank)or is it a bushing either or it should not be loose

heres the skinny
I know its messed up,I done about 40 clutch jobs since the 90's and I spoke with Jerry Bransford
The sleave that the pilot bearing rides in seems to be worn and is too small to fit in the back of the crankshaft
heres pics and a very boring vid


the sleave is solid steel

you can see the pilot bearing inside the sleave


oh and when you hear this terrible noise....its the throwout bearing




and there is my missing property

and just for kicks heres a pic I took of satrun

now If I cant get this part I will get a new one machine tomorrow

Busy day but looks like you have it under control. Was that the original parts? Thanks for sharing.

BTW your mileage will increase if you remove the 356 pounds of trail you're carrying on your skid. Lol.

im not sure T
every write up ive seen doesnt show that part,Jerry says it should be a Brass oilite sleave,This one is solid steel and its near impossible for it to have spun and wore itself down like that so If worse comes to worse I will machine
I pulled everything down bymyself...no Tranny jack

Oh and the t-case had a tiny bit of water and only a cup of fluid.....lucky it didnt burn up

I cant find my Haynes manual but what should I check on the t-case since it was so low,it always shifts smooth

If I remember right the drain plug has a magnet. See if there are any suspect bits on it. Also smell it and see if it has a burnt smell. Strange looking part and that's why I was wondering if it was OEM. Mine did not look like that. My son made an adapter for the floor jack that bolts to the trans and it was much easier when we took trans and Tcase out to replace clutch. I'll post a pic tomorrow.

I was gonna pull it all together but when I seen the water I knew I had to flush it anyway so ima run some diesel thru it before it goes back up.I removed the check valve and thats where the water was in the check valve,the drain plug wasnt low enough to drain everything out.I wonder if theres still oil inside....damn it I wish I had my manual so I can see whats inside that transfercease....how it works and stuff.

anyone have a write up on the NP231?
