When lifting and Jeep to 4" or above the question of drive line angles always comes up.

This is where JB Conversions ( http://www.jbconversions.com/pages/product...html#comparison ) comes into play. They, as well as other companies, offer different types of S.Y.E. kits but what made my mind up to deal with them was their "Super Short" kit.

This kit utilizes a tone ring and electronic pick-up sensor for the speedo, which is why they can get such a short output shaft. This set-up is pre-tuned to run correctly with 4:11 gears and a true 31" tire. If you want to calibrate to your rigs specs a "Digital Dokota" calibration device can be bought from them to get your speedo dead on.

The instructions say that you can leave the t-case in the vehicle but.......U decide.

After the t-case was removed and awaiting disassembly

This is a measurement starting at the mounting surface to the transmission to the back of the slip-yoke edge.

This next picture shows the disassembly of the rear tail housing. You need to buy a pair of good flat-head snap-ring pliers. You'll definitely need them to remove the snap rings on the factory out-put shaft.

There are 2 pry points that are pre-formed into the cases housing from the factory. Since this case is aluminum it's recommend finding these to remove the 2 halves as shown in this picture.

The main shaft, chain, and front out-put shaft pulls out as one assembly. This picture shows post this and a comparison shot of the stock main shaft and the Super Short shaft.

Make sure that everything is back as it was when you took the main shaft apart, then reassemble the front put-put shaft and chain.

While the t-case is still apart it's recommend going ahead and cleaning the circular magnet for picking up metal shavings and the oil-pump pick-up screen. Use some brake cleaner to get these clean.

This picture shows the 2 halves back together and you can also see the tone ring on top of the oil-pump. This notched piece will provide the sensor a reading for the speed being traveled by the notches on the outside of it.

Here's a comparison of how much you can shave off of the rear. Definitely worth the extra $99 over the standard S.Y.E. kit.

I haven't climbed under my TJ yet specifically to look at it yet, but how hard is it to remove the transfer case and how heavy is it?
I ain't as good as I once was, but I'm as good once as I ever was.

Your Tcase will weigh between 65 and 75 pounds and there are 6 bolts holding it to the tranny four on each Dshaft and the linkage, one electrical plug. It is a relatively straight foward job, you are more than qualified :2thumup: , but if you need a supervisor, I will glady come over and eat your food and drink your soda while you bust yer knuckles :2thumup:
The SY can be installed while still on the Jeep but I think it is done, easier and better, while on a bench..
Give a call whenever you decide though, I am always hungry... :biggrin1:
