so - I have a new Ring/Pinion coming and new half-shaft for drivers side as well since the boot was toast anyway. Not bad from a local 4x4 specialty shop - $220 everything. The question is this - did the VC lockup and then shear everything, or did the torque form the stress shear the teeth? I ask because when I looked under the truck and watched it roll forward/reverse, the drive shaft was spinning as it should.

The VC was probably bad, then the wrong sized tires thrashed the front end because it was trying to spin at the same speed as the rear. If a bad VC alone would do that to the front diff then mine would be dead in the driveway.

lol no you need to replace the VC as well. Or swap an alternative.

ok - not to sound TOO stupid, if I have a full time 4WD (4 high or 4 low only options) what the difference or what does the VC do in this set up if its locked up full time anyway?

The VC is what transfers the power in the full time. It's 90% rear and 10% front until the rear spins. VC will the. Engage and transfer more power to the front. When the fluid in the VC get hardened, it locks down and is then in need of replacement.

ok - after reading all this, and then reading a few of the TC swaps, I temped to do a late 242 swap (looks like it has the same input shaft/size) as i can get one at the local junkyard for $60 as opposed to $300+ for the VC then I have 2WD option as well.

Yea sure swap a totally used unknown 242 without a rebuild kit in place of a 300 dollar VC for the 249 which you know. That makes sense. Do you really want to put an unknown part in your truck without servicing it first? How much is that going to cost?What is the cost for the rear drive shaft to fit?

300 dollar VC

242 rebuild kit, drive shaft?, cost of the 242?, bezel on the shifter+linkage?


What is really more complicated.

I'd rather just swap a VC if I'm in a rush. If I have the time, ill buy a 242, rebuild it, and do everything right, take my time and do it right the first time.

I'd tear a lot more **** up too, but a 2wd ZJ seems amazing. I got the 13 Ram for the 2wd fun. Seems as if I have a vehicle for a certain thing.

My target at the junkyard is a 2000 XJ with less than 100k on it that has damage to the front clip and passenger door (and wearing street tires). I'm going to guess the TC is ok. My gamble, but since I don't really know the condition of the existing 249TC other than the VC is most likely dead I'll take it (I have yet to drive it).
Looking at the images/etc of the late 242, what is the difference in the rear DS? From what I've read so far, the late 242 with the .840 input shaft is "supposed" to be the same (bolt in) as my 98 249. If there is a rear difference, can it be swapped with the 249? As for the linkage/bezel, it comes with the TC unit - complete for $60.

I'd hate to see my 5.2L in 2wd....I'd probably squeal the tires every time I take off...

It's only really 2wd with the front shaft out. Other than that you are turning everything in the front. Burnouts and racing are childish.
