with an SYE yes
with a t-case drop maybe it just depends on how you wheel it

 

Yes, in addition to some other modifications as well.

What you need is a SYE kit & a CV driveshaft. Of course that would sound like "Greek" to you, so read this link from the YJ Tech Forum FAQ section and then post any questions you might have, right here in this thread! :thumbsup:

I have a 4inch lift and i run a tcase drop and im far from having my slip yoke slip out. each person has a different issue when it comes to the driveshaft. basicly comes down to throwing the lift in and messuring

 

I think you're a lot closer to the "danger zone" than you might think.

Jerry & I had to split his T-case (in the Jeep, with the skid plate in place!) in an Office Depot parking lot, and he thought he was okay too. Lot's of carnage! :brickwall

I had a 4" RC lift in mine with a stock drive shaft and never had any problems with mine. but like someone else had said it matters what kind of wheeling your going to do. i feel that i did some good wheeling with mine.

 

well as of now their is no wheeling to be done due the the bills and $$$ issue.. and at the moment i dont have the cash for a sye or rear driveshaft

 

I have put 2 kits on 2 different jeeps, One was a 4.0 the other a 2.5. Neither needed the SYE. BUT I also installed a 8.8 in at the same time, which if you are going to wheel the Jeep or install larger tires is a good thing.
I measured the drive shaft pull out and mine was only out about 1/2 inch more than stock. Which is just fine.

 

I am also running the rough country 4" with stock drive shafts. The rear drive shaft is not even at an extreme angle. No vibrations either. Time will tell I guess. I do plan on a Dana 300 swap in the future.

 

I put a four inch rubicon lift on my 91 yj with the sye .If you go with sye the driveshaft you want is a tom woods they are great.

 

i just put in the rc 4" and did nothing to the drive shaft itself, the t case drop comes with the kit but thats all you need

 

i was told to get a TJ front driveshaft and cut it to size.....im gonna try it!

 

Just put the lift on and see if the stock one will work 1st. Save the new drive shaft for later when you go SYE.

 

one thing with the tj driveshaft... make sure the shop you get it done at will balance it.

if you do it yourself without balancing your risking vibes. vibes contribute to u-joint failure and yoke leaks.

ask me how i know lol

 

ok sounds good i already had to replace one pinion seal....i like ur jeeps!!!

 

blue one is gone but that guy is selling it now, for half of what he paid for it lol... black one is like a child to me. an illegitimate bastard son of the devil.

 

buy new or machine shop, whichever is cheaper...
