Pete M Posted December 24, 2010 Share Posted December 24, 2010 polls are broken. do you want to use 4wd on pavement? if yes, then 242. Link to comment Share on other sites More sharing options...
mnkyboy Posted December 24, 2010 Share Posted December 24, 2010 Its a trade off 242 has full time but the 231 is stronger. I have both but I prefer my 231 Link to comment Share on other sites More sharing options...
codymanche Posted December 24, 2010 Author Share Posted December 24, 2010 okay? so for offroad use how is it my friends say its bullet proof! and the other has a 231 and said hes never had problems. none of my friends had problems with any other transfer cases Link to comment Share on other sites More sharing options...
Pete M Posted December 24, 2010 Share Posted December 24, 2010 the 231 is rated for a bit more, but both t-cases will work great offroad. :thumbsup: Link to comment Share on other sites More sharing options...
mnkyboy Posted December 24, 2010 Share Posted December 24, 2010 My 231 seems more trouble free,It shifts in and out flawlessly. I have to play with the 242 to get it to shift correctly. I think if you have a 231 and it works I wouldn't go out of my way to put in a 242. Link to comment Share on other sites More sharing options...
Pete M Posted December 24, 2010 Share Posted December 24, 2010 I would go out of my way to put in a 242. I like awd on the pavement. :D Link to comment Share on other sites More sharing options...
codymanche Posted December 24, 2010 Author Share Posted December 24, 2010 well i asked the old man he said that i would get less mpg with the 242 but i want something thats bullet proof thats going to last pete i got pics of my lift and stuff but i can't put them on here having the same problem again lol can u help me out Link to comment Share on other sites More sharing options...
Pete M Posted December 24, 2010 Share Posted December 24, 2010 getting less mpgs is a myth. I've noticed no difference between 2wd and awd in our Libby. also, THERE'S STILL 2WD AVAILABLE!!! It's not a full-time case. And it has locked 4wd high-range too. It's got all of the above. :D Both t-case are going to last. we're just splitting hairs when it comes to longevity. yes, the 231 is "stronger", but it's not that much stronger. Both will do you fine.

mnkyboy Posted December 24, 2010 Share Posted December 24, 2010 How is buildable is the 242? I know there is tons you can do to the 231. Link to comment Share on other sites More sharing options...
Pete M Posted December 24, 2010 Share Posted December 24, 2010 there's not much aftermarket support for the 8.25 either, doesn't make it a bad axle. awd is awesome. period. :banana: If one does not need or want awd, then the 231 works great too. It's win-win here. :D Link to comment Share on other sites More sharing options...
mnkyboy Posted December 25, 2010 Share Posted December 25, 2010 I guess it depends what you plan to do with your jeep. For offroad I would stick with the 231,stock its stronger built its much stronger and has aftermarket support,its also more common if you do need to replace it. If you use your jeep on wet or icy pavement alot then I would get a 242 Link to comment Share on other sites More sharing options...
Darren Posted December 25, 2010 Share Posted December 25, 2010 I yanked the 231 out of my XJ, sold it for $75, and installed a 242 I bought for $40. I don't believe the 231 is much stronger in stock form. Having that full-time (AWD) option is awesome, and I've never had linkage issues. Link to comment Share on other sites More sharing options...
91coMANche Posted December 25, 2010 Share Posted December 25, 2010 It was my understanding that stock for stock the 231 and the 242 are similar or the 242 is a hair stronger. If you update to a non-hack-and-tap short tailshaft then you will get a thicker mainshaft, which is substantially stronger. Even if I am wrong and the 231 is stronger (it can't be stronger by much) the weak link is the case and they are ridiculously difficult to break anyway.

mnkyboy Posted December 25, 2010 Share Posted December 25, 2010 Stock for stock the 231 is stronger,not by much but it is stronger. We have established that it would not be a strength upgrade question is does the OP plan to keep it stock and would he benefit from the full time 4wd on the road.

91coMANche Posted December 25, 2010 Share Posted December 25, 2010 I can really appreciate the 242 over the 231 for on-road use myself. It also doesn't hurt trying to tow around certain bends...I hated my TJ 231 whereas I loved my ZJ 242...then again my favorite has to be the WJ 247 I used to have. No thinking just goose the skinny pedal as you please Link to comment Share on other sites More sharing options...
mnkyboy Posted December 25, 2010 Share Posted December 25, 2010 Thing is the OP is asking about offroad use not pavement. For his purpose he should just leave the 231 in there,its a little stronger and can be upgraded if he wishes. I don't see the point in going to the 242 if he doesn't need the full time 4wd Link to comment Share on other sites More sharing options...

I don't see the point in going to the 242 if he doesn't need the full time 4wd You're right. The only time the 242 helped me off the pavement was when running high speed on mountain roads that weren't paved. I only used full-time so I would get good turning in some conditions but yeah its not as vital for everyone. Link to comment Share on other sites More sharing options...
mnkyboy Posted December 25, 2010 Share Posted December 25, 2010 I looked up the specs on the t-cases and here's what I found. 231 maximum torque capacity is 1885ft lbs vs the 242 at 1486ft lbs Link to comment Share on other sites More sharing options...
codymanche Posted December 25, 2010 Author Share Posted December 25, 2010 well when it comes to offroad use I'm looking to do like jeepspeed and be able to crawl. I'm not running 35's i got 33's. i heard with 35 u can't feel the difference in 35's but 33 u could with out regearing Link to comment Share on other sites More sharing options...
mvusse Posted December 25, 2010 Share Posted December 25, 2010 Don't think he poll matters because it is still broken. For Jeepspeed (I imagine desert) I would not go with either. The high torque and horsepower needed would need alrger transfer case than that. And a larger engine than the 4.0 Running the 4.0 I would go with the 231. Only time I think a 242 is going to really be helpful is on gravel or snow covered roads. For an offroad rig, especially one that has to survive high speed racing, it's all about strength, where the 231 is a bit better. But building a dual purpose rig that can do well in Jeepspeed AND crawl is expensive. Otherwise you end up with a compromise that sucks at both.

codymanche Posted December 26, 2010 Author Share Posted December 26, 2010 well the rules of jeep speed is the jeep has to be almost stock motor wise u can stroke it out but it has to have a 4.0 based engine and suspension has to be a certain length too the rules of jeep speed are way strict. I'm just looking for something that i can do both of jeepspeed and crawl Link to comment Share on other sites More sharing options...
terrawombat Posted December 27, 2010 Share Posted December 27, 2010 I'll add a little something to the strength argument. The 242 transfer case is a very common swap for the Grand Cherokee ZJ 5.9L crowd since the stock case (the 249) usually has the viscous coupler go bad relatively early. Those trucks are putting out 250HP and 350Ft-Lb. of torque in their stock form (A LOT more torque than any era 4.0L). Many of the guys that have done the 242 swap in their ZJ's are putting out much more than that because of various modifications. Although most of the guys aren't off-roading their rigs, they are taking them to the drag strip, which is another brutal environment for drivetrains. I have yet to hear of any of those guys breaking their transfer case. Link to comment Share on other sites More sharing options...
codymanche Posted December 27, 2010 Author Share Posted December 27, 2010 but for what i wanna do I'm just looking for advice on what i should do for both jeepspeed and crawl Link to comment Share on other sites More sharing options...
Pete M Posted December 27, 2010 Share Posted December 27, 2010 both will work. if you don't need awd for anything, then just get the 231. :thumbsup: Link to comment Share on other sites More sharing options...
