Plan for Tuesday was finish the transfer case SYE and 2Low install. Went outside, and was surprised to find a few inches of fresh snow. My Jeep didn't even have a transfer case so it didn't really matter to me.
Tracked down my loaner set of snap ring pliers. These are pretty trick, and make snap ring removal/install a breeze.
I began disassembling the case. For the most part the 97+ cases are like the earlier models. The biggest difference is in the tail housing. Early models are a breeze to remove, late models have about a dozen parts holding it on.
First thing that had to go was a pressed on "slinger" on the tail shaft. AA recommends using a long two jaw puller. I chose the die-grinder method. Since I wouldn't be reusing these parts, I took a cut off wheel and slowly cut away the pressed on sleeve part to relieve the stress. Then I took a chisel and "peeled" away the sleeve. At this point I could remove it by hand.
Beneath the slinger I found another pressed on retainer. I'm sure there's another tool for this, but I used a pry bar to walk it off.
Beneath that I found an external snap ring.
With the snap ring removed the tail housing still wouldn't budge. So I continued to dig deeper. Out came the seal (I wouldn't be reusing this).
Not surprising, I found another snap ring under the seal (you'll want to remove the external one on the shaft).
Finally I got to a point where I could remove the tail housing. It's held on with six 10mm bolts. Be careful when prying it off since the case is cast aluminum. Also, remove the speedometer gear prior to removal. The retainer is a 13mm hex, and then you can pull the speedo gear assembly out.
Next step was removing the front output yoke. Use a 1-1/8 socket (preferably an impact socket), and an impact wrench. If you don't have an impact you'll have to get creative.
At this point you're ready to split the case. Remove the case bolts, and use the designated pry points on the corners to split it. Also, note the oil pump is positioned on the outside of the back half of the case.
Case split in half. Mine must have gotten some water inside, there's some strawberry milk looking sludge around the case.
Push the front output shaft up, and remove the chain. Then remove the mode spring, shift fork, and main shaft. Keep everything oriented to how it's been removed. Organization is key.
Remove the 7/8 bolt off the bottom of the case. This holds in the shift detent pin (careful it's spring loaded), and lets you install the new 2Low shifter.
On the main shaft you'll need to transfer the main drive sprocket to the new SYE shaft (again pay attention to it's orientation). It's held on with a large snap ring. Some of the earlier models will require you to press off some needle bearings. Find an appropriate size object and tap them out.
