Stupid Newbie SYE question

I know what it is, I know what it does, but I've never actually seen one on a YJ. Below are some pics from below and slightly behind the tail of the transfer case, is the universal joint farthest to the left the the pics the SYE?


Thanks for your patience, I've read enough to be dangerous, but I've yet to see some of the stuff mentioned on the forum in person so I thought I'd ask.

No, what you see there is the stock slip yoke. An sye (sye= slip yoke eliminator) would replace the slip yoke. The slip yoke being the shaft that goes into the transfer case.

This is what a transfer case with an sye looks like:

The stock slip yoke is good until you start lifting your rig, which increases the angle, therefore the distance between your rear end and the transfer case. The increased angle will cause vibrations and if lifted too much you run a risk of the stock driveline pulling out of the transfer case all together which is a bad thing. A four inch suspension lift probably should have an sye installed but you can make it with out it ( as I currently am) if your wanting to go more than 4" of suspension lift I would say you definitely want an sye installed.
Btw - from your pics it looks like you have a leak at the output shaft of you transfer case, there is a write up on fixing this in the FAQ section under "transfer case"

Here is a shot of mine with a double cardigan ( double U-Joint) rear drive
shaft. Both help to eliminate vibes due to steep angles after lifting.

jeep108, I got a question I am at about a 4in lift, how did you go about not needing a SYE kit? Did you drop the TC if so how much, I am runnin into the proble where my slip yoke is hanging out the tc a little bit and its causing it to leak, and I Just replaced the seal, it is leaking a little still..!

I have a 1/2 T-case drop that came with my 3.5 inch lift and then I added a 1/2 inch shackle lift and my drive line has no vibes in 2WD, I am sure it does in 4WD because it did stock at around 35-40mph.

I did a 1" motor mount lift which improved my driveline angle, I had a few vibes at first but it went away after I drove it around a little. Did you replace the output shaft bushing when you did the seal? If not it would be a good idea to, some times the bushing gets worn and allows to much play which can cause the seal to deform and leak.
