Hey guys, I bought a SYE kit for the Rams NP231 about a year ago. I was thinking about saving it for the XJ. I have the stragith D30 without the vacuum disconnect...so I have suspected it wasn't the 231. When I finally looked under my Jeep and I discovered it was the 242, not the 231. Isn't the 242 supposed to be full time? Cuz it doesn't drive my front wheels! It stays in 2hi and doesn't move them. I jacked up the rear and put it into gear to see if it could find a noise....but it never drove the front to pull it off the jack...(I didn't know it was a 242 till I looked at it while it was up there....I didn't do this as a stupid test to see if it will pull the front!)  How is my t-case supposed to operate? It has 2wd, Hi-lock, 4wd, low lock and 4lo....I think....not sure if I remembered those correctly, but something like 5 different options for the gear selector! Is hi-lock where it spins the front? I would think that would actually be 4wd!!! Or are those two with "lock" not really a gear selection? Also, will my SYE kit work on the 242 or do I have to pull a 231 from UWI? Thanks for the advice guys! |

Yep, the 242 is full time, which certainly has advantages, as well as disadvantages. It's also the aluminum case.... let me say that again... ALUMINUM case. As far as the SYE fitting both, check Rubicon Express' web site... look like some are interchangable, but, check here first, read, and decide if you want to go forward with that: www.jeeptech.com/xfer/ |

What are you trying to say about Aluminum? The 231s are aluminum as well. I know I have like 2 NP231s for the Ram and they are all aluminum....your t-case is aluminum as well! I went to that site and it doesn't have much info. I went to upgrades and they gave the usual stuff about the Atlas.....I will check some other sites to see if the kit works. At the very least, I might just go to UWI and get a 231. I need to check REs site still.... Or....I wonder if one of my Dodge 231s would fit? Probably wouldn't have the same number of splines or shaft diameter...... Maybe I should just not worry about it! By the time I get money for a big enough lift to warrant the SYE, I will probably have the small block in there!  |

I did some more searching and found a pretty awesome site that shows the NV242 case instal! Unfortunately, it appears that my current JB Conversions 231 kit isn't compatible. Oh well......I been wanting to put it on the Ram anyway! Cuz I need a driveshaft e-brake and the flange with the 1350 stuff is what I need to do all that. However, the RE kit does say it is for both.....I wonder what the difference is.... But at least there are two companies that make the kits for the 242 so it isn't like I don't have any options. Hey Lyle, when you said advantages....what were you thinking of? Is there something better about it? My 4x4 experience has been that selectability is best.... [Edit] Oh yeah, here is the site! www.polytropia.com/cherokee/sye.html |

Hey Lyle, when you said advantages....what were you thinking of? Is there something better about it? My 4x4 experience has been that selectability is best.... The advantage I was thinking of was not for off-highway. The fully automatic Quadradrive system (NP249 combined with Vari-Lok axles) in Nena's Grand is perfect for her driving (99.99% On highway). It's great for snow as she doesn't have to do a thing, it just does what it needs to do to keep her moving (even driving only one wheel at a time when necessary). Off highway, I agree, selectabliity is best, but, I can still pull the lever in the Grand back to 4Lo, and it's all locked up. On the "aluminum" comment.... my bad. Had brain fade (happens at my age)... and I was thinking of the aluminum housing on the Dana 44 on the Grand. I still think that's a bad idea, and I guess it was on my mind. |

Hehehehe....mine ain't no full time system like the Grands. Mine is the sucky system.  I think the chain is slipping off of the teeth or something...cuz there is something wrong with the XJ....I think it is the t-case or maybe the tranny. But it sucks to have the dang thing jerking all over the road and making bad banging noises.  231 here I come.... |

I bet your banging noise/jerky motion is the (viscous?)coupling in the t-case. It is this item that allows the XJ to be driven on the street. If it is in (Wow 4 two letter words in a row!) 4WD on the street this coupling acts as an open differential to allow slippage front to rear.
BTW, right after we bought the Durango with a 231HD, there was an article in one of the 4WD mags that said the 242 was stronger than the 231.

Create a vacuumy thingy? What was that....is that a replacement for create a vacuums? [Edit: I am trying to say sukks!] lol Yeah, I would imagine that the 242 is stronger and I don't really mind it. But it is giving me fits, as I don't think there is anything else wrong with the XJ. I think the t-case fell apart due to my foolishness. Can you believe it, I never serviced the t-case when I bought it....flushed and filled the motor, tranny, diffs, etc....but I planned on getting to the t-case. Well, then the motor went....then all the issues with the Ram, school, work....I kept forgetting about it. Once it started making the noise a couple weeks ago, I drained it and a couple of cups of liquid molasses oozed out!  It took almost 45 minutes to take the fill plug off! Breaker bars and big wrenchs weren't cutting it. It didn't have the little pipe plug type fill but the one with the big 1 and 3/16ths nut and it got all rounded off! I bet that thing had never been serviced in its 230k+ mile life!!!! Finally the impact busted it loose....factory loctite and seal were on it! Well, at least it isn't acting up *as* much. |
