Irongrave SYE kits are a good thing to have. I like having one on my rig. t-case drops are pointless band aids for drive line vibrations. Why install a lift then lower the t-case where it can get snagged on rocks. If you get a good slip shaft you'll be fine if you add to your lift down the road.

mrobison1 Yea areplace the seals. I run a 4 inch pro comp and have no issues with vibrations. 3.5 you will be fine without a SYE. 4wd told me that you don't really need one untill you go to a 5 inch lift.

kicksforlaughs The car is leaking from the transmission in the front and the transfer case in the rear. Also from the oil pan and differential So basically I just need to go on a seal shopping spree?

Jeep_Geek I ran a 3.5inch with a t-case drop for 3 years with no problems. I would say you should be fine if you are not getting vibs right now. Just expect a little less life out of your u joints, not a big deal. I would do the seal first.

Replace the seal! You shouldn't need an sye kit and the custom shaft..... now you ask if I have one with a 4" lift.... yes yes I do not because I needed it because of the lift but because I destroyed my tc and yoke and bent my driveshaft all at the same time..... rocks+skinny pedal+young stupidity=disaster. So I put one on since I was putting in a new tc, needing a new drive shaft and redoing my yoke on the d35 anyways. Obviously you had a problem with your seal before hand and take care of that if you have no vibes and your lift kit came with a tc drop then I say ur golden.

hazaelnolasco yes you need one, and the leaks would be worse if you dont make it, it needs to be extendable
