Moses; I pulled the 231 tonight and re installed the 242 as I think I will rebuild the 231, it started making noises....my luck, oh well. from what I understand the spline cut difference is in the TC not the splines attaching to the trans. I think once I get the rear pinion turned up ill feel better about the cv shaft. when I get my shims I will get new center bolts as well. once I get straightened around I will post some pics of the ole girl Dave

Moses; Thanks again for the info, I think turning the pinion up will allow more travel on the spline, I will print off the link next week and do some adjustments, I took it for a drive tonight and got some vibration & noise, I am going to try driving it without the front drive shaft tomorrow and try and isolate the vibration, once again thanks for the help. much appreciated.

Moses; I swapped out the T-cases today Everything worked well, both had 23 spline count and the 231J already had a AA short shaft "fixed yoke" kit already installed, I need to order the proper gear for the speedo though as previous owner had it geared for 32" tires where as I am running 31". The rear double cardan joint shaft looks like it is stretched out to the limit which makes me a little nervous. It clocked well it all stayed above the crossmount Now I have another question I hope you can help me with? Here is the measurements I got using an angle meter, can you tell me what degree of shim I require? and please explain to me how you got the measurement? Can I use the same formula for the front diff as well? I realize there is steering angles involved, I have had the front end alignment and it tracks well however not sure about the caster angle as alignment shop said it was within specs. I have adjustable lower control arms

Moses; Yes there is a slip joint on the 242, I have a front spare driveshaft with a tight double-cardan joint that I believe will work, I am only lifted about 3 - 3.5 inches and running 31inch tires. Not sure if it is the right length. I guess it will vibrate till I get the rear shims installed? Going to tackle it this weekend. I could just use an angle finder on the rear diff input yoke to find degree of angle required? I was told the 231J was from an 89 wrangler and that they are clocked differently? and it may hit the floor of the vehicle ? does that sound right to you? I thought all 231J used same case?

Moses; I looked and looked at those sites, I think I may have got lucky to an extent, I believe the previous owner installed a SYE in the 231J (from wrangler) and it was getting me turned around, having said that I am going to remove the 242J this weekend and hopefully it interchanges without changing inputs, I appreciate your help, thanks Dave

Gents. Looking for a little guidance, i have a 94 Cherokee XJ with a 242J behind a AW-4 automatic on the TC tag reads 242J 5209 8046 5 19 94 2 272 I also have a 231J with a tag that reads 231J 5209 9212 1 14 98 3 272 Are they interchangeable? I have a spare front xj driveshaft and it fits both outputs, although the cases do appear to be a little different, the 231 is from a wrangler with fixed outputs front and rear, as well as having one sensor in the front case half and another sensor on the back case half. the 242J has them both together on the back half. The shift linkage looks to be the same. The 231J has 23 spline input, not sure about the 242J as it is my daily driver, Any help would be muchly appreciated as there is so much info on the net i get it buggered up trying to get it straight
