Driving without it can cause problems, and will probably take a lot of life out of your VC
2003 WJ in Jeep Green Metallic, 4.0/242/4.10's. 4" Teraflex springs w/ RE monotube shocks and IRO short arms, cheap intake w/ amsoil filter, 2.5" hi flow cat and back exhaust, lots of lights and other misc crap.
That's what I've heard, but I've also heard that the 249 transfer case on the 1998 is different and won't damage the VC if you drive without the front drive shaft.
I think I'll play it safe though.
what front end did you put in thats larger than the D30?

96+ can be run without a front driveshaft with minimal if any issues. A driveline shop will be able to shorten your driveshaft and rebalance for a nominal fee.
I seem to remember that the OP had a failure in his stock D30, so got a D30 from another Jeep. For some reason (anomaly?), the differential case was a bit longer. As I remember, it was a low pinion 30.
"How the heck do you get there?"
"Duh! Big RED Jeep!!!"
Okay. I swapped it out because the original got damaged (axle housing on left side bent back and control arms on that side bent pretty bad).
I looked at many junkyards, but couldn't find the shorter one like i had. It sounds like it is the long/short pinion thing.
The only Shorter one (like mine) I could find was damaged, so I figured I'd try the longer one and also get the driveshaft out of the vehicle it came out of.
For some reason, the driveshaft that it came with is even longer than my original (unless the guy at the junkyard got it mixed up with another one). Maybe the junkyard jeep had a different engine and/or transmission which made the transfer case further back.
Both mine and he junkyard one had the type 249 Transfer case. But, the one at the junkard is a '96 while mine is a '98.
I'm in San Jose, CA and figure I'll check Southbay Driveline to see about having the driveshaft shortened.
I do plan to change the yoke out so I can use the original U-joint driveshaft instead of the CV joint one it came with. That'll be a hastle because of the pinion bearing pre-load, but I'll try measuring the rotational torque and set it back to the same value ( I don't think I can use the nut position as a guide for getting it back to where it is since it'll be a different yoke). It's possible that the original driveshaft will fit (have enough play in the slider), but I'm not counting on it.
