Transfer case question

My transfer case is all jacked up it makes a popping sound like my chain is popped off. I'm looking at rebuilding that one but I need one this weekend and there are a lot in the local scrap yards but none are an 88. Could I take one from another year and would it bolt right in or what should I do

I suspect you could rebuild the one you have in less time than finding, removing the scrap one, and removing yours, and replacing same. That...is a fair amount of work.
Pulling yours(really doesn't NEED removing, can be worked on in place), replacing the chain, and re-assembling it is less work, a couple hours.
The new chain is $$ though. The bearings are also, as is the main shaft. (the roller bearings are like $55 at Jeep, chain is $75 as is the main shaft) plus the new fluid and sealant.

I believe in 94 the input shaft changed lengths, so if you get one 93-earlier you should be good there. You have a 21 spline input shaft so stick with a 4 cyl, or a 87-90 with a 4.2. 4.0s will have a 23 spline input shaft. Hopefully someone will correct me if any of my info is wrong.

if you take a t/c out of an early 4.2 make sure the tag says it's a 231...they used 207's on the very early sixes (just '87's I think)

So try and find an 87 inline 6 and it should work I'm also not opposed to changing things out of the t-case

Most 87s are a 207, not a 231 that you want. 88-90 6 cylinder, or 88-93 4 cylinder would be a good start.

or just get a TC from ANY 88+ YJ regardless of motor... then IF you get a different one, swap your input shaft into it.
saves a lot of time picking through, IMHO

I run a case out of a 95 4 cyl. in my 87, the change in the later cases was internal (different cut gears). any standard shift 21 spline case will work. with the newer case you will have to switch your speedo drive but thats simple.

Thanks guys I got it figured out. I took the gears that the chain run on out of an np231 c hd and put them in my original case and put the thicker chain on and it solved the problem.
