wj transfer case help
So I have a 2003 wj 4x4 4.7v8. I THINK it has a NV247 tcase the shift positions are 4 all time, N and 4LO. Is this the NV247?
I want to swap my NV247 for a NV242. Is this recommended? Is it better than the NV247? Is it a straight swap? I really want the other 4x4 shift options and really want the 2WD position as well. Thank you very much! |

Welcome to CF!
Yes, you have the NV247. There are 2 different 242 cases for the WJ. The NV242LD uses a rubber boot on the output shaft and the NV242HD uses an aluminum output housing. I'm assuming the HD is used in the V8s. I believe my 4.0 has the HD model because it has a slip joint output shaft. Also I'VE BEEN TOLD if you get one from a WJ, there is no problem with matching the input splines. The WJ cases shift by cable and have no speed sensor in them. The speed sensor is inside the transmission. You can use your existing shift quadrant and just change the indicator bezel (or not). There is a light in the dash cluster that tells you when you're in "part time", but IDK how you wire that. I think it just involves changing a plug. The nicest thing about the 242 is it's "shift on the fly" at any speed from 2wd to 4wd. The only time you need to stop is to go to low range. Check out wjjeeps.com for info. |

So all I need to buy would just be the tcase? Are my driveshafts still gonna work?

Again, I'VE BEEN TOLD, the only physical difference between the 247 and the 242 is about 1/4" in length, HOWEVER, the V8s use the D44 rear axle and the 6 uses the D35. On the older ones, there was a difference in the differential universal yoke size between the 2. If your V8 driveshaft fits the 242 output shaft, you're good to go.

Any one know where to get good used ones from?

If you google it, all kinds of retailers will pop up. At my Pick&Pull, they are $75 for any t/case. You just have to know which one you want, as in year, type, and you have to know if it fits.
Okay, I just did some research and you need a 242HD from a WJ V8. the 242j from the 4.0 is different. The problem being the 242HD is sort of rare. Also the difference in length is 2" so you'll need the driveshafts as well. |
