im wanting to put a sye on my xj .. how do i need to go about this ? what would be the best brand to go with .. i have the np 231 t case. any advice at all would help thanks
 
I went with Advance Adapters for my SYE, haven't installed it yet, so I don't have any experience with it yet.
 
From what I understand the most common is to go with Advance Adapters SYE kit and a front shaft from another XJ. You can also order a shaft from Olivers, Tom Woods, etc. You can do the SYE conversion without taking the tcase out of the Jeep though I imagine having it on a work bench would make things easier.
 
It's fairly easy, just make sure you got a really good set of snap ring pliers. A extra set of hand is also nice. The TeraFlex kit is also nice.
 
dont know whats in mine bought it used low gear is bad so i have to go into it but thats ok i used the front shaft from a 3/4 ton chevy cv joint thick wall tubing and greaseable pin works great only cost 100 buck with new u joints
 
Advance Adapter. Usually right around $500 with New Dshaft. The install is really easy and the instructions are very detailed.
 
Don't meen to sound dumb, kinda new to this, byt what is "sye"
 
The only difference in some of the kits is the rear bearing diameter and how the mainshaft is machined to accept it. I've installed both the Advance Adapters and the Rubicon Express units. Its been a good while but I believe Rubicon offers a heavy duty version with a little bigger bearing and rear adapter for the rear yoke and case. One I recall was a remachined version of the stock shaft, which made it a little weaker. I personaly like to do them on a bench where you can clean em up and inspect your work easier. You'll definately need a good set of snap ring pliers like stated above. Not the "snapring" type that has eyes made in them. This ring is more of a steel band that must be spread enough to slide over its machined resting place on the mainshaft. Screwdrivers or other shenanegans want get it done. The only tedious part is making sure the fluid recirculation pump lines up and goes into place on reassembly. Personally I would stay away from another product commonly refered to as a "hack-n-tap".

hack -n-tap?
 
I just did one this morning, it's fairly easy. The hardest part is dealing with the snap rings. I would recommend pulling the case, you will do better work with it on the bench instead of under the vehicle. The only special tool needed is a 9/16" ratchet wrench. Some of the nuts are impossible to get off with a regular ratchet and socket.
 
I like the JB converions shorty SYE. Replaces the stock speed-sender with a small magnetic pickup making it shorter than some others.

Yes the snap rings will drive you crazy, Have a nice set of snap ring pliers and take your time. Its almost like the old game of operation, You have to be easy and steady.

I did mine on the work bench and it is fairly easy to do, The hardest thing was pulling it out of the jeep, Getting to some of the bolts are a bitch, Like Matt said.
 
This helps when it comes to the snap rings :flipoff2:

And yes I have fought them before too.
 
i just fixed mine very easy to do but the locking ring plyers are a must omg you wont do it easy without them there is a difference in the years to the one i have you have to pull the needle bearings out of the older style the newer ones dont have any
