ok so i am rebuilding my np231 these are the parts i have.......

front output seal
rear output seal
oil slinger
and 3 diffent bearings
i think i have all that i need....i know i need a chain but what else


oh and the bearings the code on the box is 26930,87983, and 26929
but i dont know the names

 

There are gaskets you can buy to seal the case but i just use silicone gasket maker. Make sure you get some that is specifically made to be ATF resistant. I use a brand called "the right stuff", worked great when i did my rebuild.

There are also the little plastic/rubber things that are on the shift forks.

And a good set of snap ring pliers and lots of patience. Those snap rings can be a pita

Good luck

no doubt. those and getting the case to align correctly, for some reason, took me a long time.

 

You should put in new sprockets with that new chain.

X2 on the silicone

 

NOW is a good time to throw a SYE in....hehehe

LOTS of rags.
SEVERAL cans of Brake Cleaner.
Tube of assembly lube. (Works great for the seals)

Good rubber mallet is a PLUS.
And as much patience as you can scrounge up.

Before removing it from the vehicle: After removing front driveshaft. Drop it into 4wd (Hi or Lo) and loosen the front yoke retaining bolt.
It can be a royal PITA anytime after this, especially on the workbench.

I just got done rebuilding my NP231.
Had some issues with it before it got yanked. (Snapped the rear output shaft retaining clip caused major carnage inside)
Installed a Advance Adapter Slip-Yoke Eliminator and the proper speedo gear.
Used my original front shaft, that was rebuilt two months ago, in place of the rear driveshaft and I am currently rebuilding another to throw on the front.


Use "good" black silicone. Why BLACK? After you have it back in, the black disappears under the fresh dirt and new grease/oil

 

Does anyone know of a complete kit. I found ones with gaskets and bearings but no chain and sprokets.

What you guys want is a Master rebuild kit... and not all are complete.

I'll dig up the part#'s for ya...

 

its all on the site i posted even great breack downs of all parts for jeeps

 

here you go theres a part number list below this on the site

 

Link below is what I found for google search "np231 master rebuild kit" Is this enough? I've never opened a T-case before so I don't know what to look for.

Right now it sounds like grinding when I accelerate quickly from a stop or when going up a steep hill (offroad) I thought a T-case rebuild would cure that noise.

Whats the best way to get the T-case seperated from the 99 xj classic stock?
