guess il be without a jeep for a few weeks which sucks ass
You'll probably get by on the street for a couple weeks as-is.
When you took it wheeling, and drooped the rear axle, it pulled the yoke out of the slip joint.
On the road, that's a lot less likely to happen.
wat if i take the end off my rear drive shaft and put it on the front one wont it work
I guess I confused you with the front-in-the-rear trick. I'll try to explain better:
Your immediate problem is that since your lift, your rear driveshaft is a bit too short. This is because by lifting the jeep, you effectively increased the distance between the t-case and the rear axle.
There are three potential solutions to that immediate problem: Ordering a custom-made, longer driveshaft; Having your current driveshaft lengthened; Or (maybe) replacing the slip-shaft at the top of your d/s with the slip-shaft from a YJ Wrangler, which may be 1" or so longer.
These would get you going again, but wouldn't fix the underlying problem.
That underlying problem is the slip-yoke design itself, on the back of the transfer case. To really fix this, you need to install a slip-yoke eliminator kit. This will replace the slip-joint on the t-case with a fixed output yoke.
Once you do, however, you'll need a new driveshaft to work with the SYE. The new shaft will have a double u-joint (double-cardan) at the top end, and a slip fitting in the middle of the shaft.
You can order one from most any driveshaft shop, I recommend Tom Woods. Or, as a less-bulletproof but cheaper option, you can actually use a stock front XJ driveshaft in the rear, with that slip-yoke elimiator.
See, that's all the typing I was trying to avoid...
