#1853 of 2589 231j Transfer Case for 94
Feb 03, 2006 (8:41 am)
I need to replace the transfer case on my 6cyl., 1994 Jeep Cherokee Sport, 5spd MT. The name plate says it is a 231j.
I'm looking around trying to find a used one to replace it with. Does the replacement need to come out of a 94 with manual transmission or are there other years that will fit? I've seen descriptions refer to 21 or 23 spline, does anyone know which the 231j is or which one I need?

You might try using a plastic tank repair putty. I found some in an auto parts store last week. It is near the JB Weld and other metal repair products. It might do the trick. Otherwise, a new radiator is in your future.

I'm not familiar with a "231j". Is it a "New Process" t-case? It should be an "NP231" unit. You should also have the Aisin AX-15 tranny. This t-case unit is used with both the 4 and 6 cylinder models. The only difference is the number of input gear splines on the t-case. The 4 cylinders use a 21 spline gear whereas the 6 cylinder uses a 23 spline gear. I have read there were three different length input gears used throughout the years. However I have never been able to verify that info. If you happen to find one from a '94 Cherokee, that would be great. However, I'd bet you can use one from around '90 to '01. My '01 Cherokee Sport has the same t-case in it as my '95 Wrangler. Try going to Ebay and searching for "NP231". You should be able to find a good one for $300-$350.

You should be able to use a t-case from a Cherokee with the auto tranny as the mounting will be the same. However, that could be where the different length input gears comes into play.

Thanks, I found some and it appears that it might do the trick.
#1858 of 2589 Check Engine Light ON 2001 Cherokee
Feb 07, 2006 (4:51 am)
At approx. 76,000 miles the check engine light came on and idle speed seems to be alittle high even though the heater/ac is off. Happened once before at 12,000 miles, then under warranty, the dealership replaced the fuel pump gasket which fixed the problem. Now, I think the problem maybe one of the O2 sensors. (1) Does anyone know if its possible to test these sensors with an ohmmeter? and if so, what kind of readings should I get? (2) Also, if I replace the sensors or any other part, will I need the computer to reset the light?

Before you start throwing parts at it, have the codes read. You can either take it to AutoZone, or some other parts store, and have them read the codes for free, or you can buy your own scan tool. A scan tool will allow you to pull the codes, find out what they mean, and erase the code to turn off the check engine light when you're done. They can be purchased for under $100 for the basic model. I have the $150 model. It has saved me and my family/friends well over $1,000 in diagnostic/repair bills. Best of all, you can use it on all your other OBD-II cars as well. All 1996 and newer cars are OBD-II compliant.
As far as I know, you cannot test an O2 sensor. If I'm wrong, hopefully someone will chime in and correct me. I'd love to have that little piece of knowledge stored away.
Your high idle could be nothing more than a vacuum leak.

#1862 of 2589 1996 Cherokee engine
Feb 11, 2006 (5:47 am)
Anybody know where I can get internal engine parts for a 1996 Cherokee 4.0L? Besides the dealership? Seems as though everyone has parts for 1995 and older. I've tried a couple of local parts stores and spent hours looking online. I doing a minor rebuild for an engine swap into my Wrangler and I really need new rings and bearings.
