You change the shaft if u installed a sye. If not u just keep it until u r going to upgrade. But u should have a tc as drop installed at least.

4" of suspension lift is right at the point where a longer flange-mounted aftermarket CV driveshaft is recommended. As the suspension increases the distance between the t-case output shaft and rear axle, the OE driveshaft length starts getting marginal and in the right offroad situation, it could pull apart at its slip-joint.

You don't need a SYE since your Rubicon's 241 tcase doesn't have a slip-joint output shaft like the standard TJ's 231 tcase does.

I don't believe you need an SYE on the Rubicon. When I put my new DS on mine I didn't need one. Don't waste your time or money in a TC drop, it was the first thing I got rid of when I bought my Rubi. How much did your DS pull out of itself when you put on the lift??

If you plan to go off road and actually go OVER obstacles you don't want the TC lower. Read what Jerry wrote, you don't want the DS to pull apart as the suspension flexes. Invest in a good aftermarket DS...in the end it'll cost you less. The PO of my Jeep had a 6" lift w/ the TC drop, first thing I did was drop the lift to 3.5", ditched the TC drop and bought a new double carden DS.

Your Rubicon does not need an SYE since it doesn't have a slip yoke, but at 4" of lift, you would need a double carden drive shaft to get rid of the transfer case drop (preferred), or if you want the transfer case drop, have your existing drive shaft lengthened.
