What would cause it to vibrate? What drive shafts are you supposed to swap with?

what causes it to vibrate is the angle the drive shaft when you lift your jeep and as for drive shafts im not sure you should be able to buy an SYE for the rear drive shaft but I dont know what drive shaft you would have to get for the front one. but I could be wrong about needing an SYE for the rear drive shaft since I dont own a wj yet.

Vibes come from excess pinion angle. Which is why, as I mentioned before, you may need adjustable front uppers CA's. The drive shaft you have has nothing to do with why it vibrates. However, cv-style shafts cannot handle the angles from lifts more than 3" and they will wear much faster and will likely fail almost immediately. A u-joint style shaft will solve the failing issue above 3", but will not solve the vibes until you get adjustable upper CA's.

But again, some people get vibes, some dont. So, you may not even need the upper CA's. I have the RCX kit. My Jeep also came with a u-joint style shaft in the front. I have no vibes what so ever and dont have adj uppers. I only run exactly what came with the kit and it works flawlessly.

Also, no Slip Yoke Eliminator needed on WJs until you get above 6" of lift.

Is the u-joint drive shaft an aftermarket part or do certain models come with them?

Some of the later models came with the u-joint style shaft. My 02 came with one. Check out Car-Part.com--Used Auto Parts Market to search local junk yards.

Can you do a straight swap from CV to U-Joint drive shaft?

I've tried searching for answers but the 3 character limit doesn't allow me to search for "CV".

You would need to swap yokes at both ends as well. It can be done, but the pinion yoke requires a specific torquing sequence as it uses a crush sleeve. If you remove the old yoke and record how much torque it required to loosen the nut, as long as you tighten it back down to the same amount of torque, it should be okay. The yoke at the transfer case is as easy as pulling the old and putting the new one one.

Good to know. Thanks for all the information.
