Managed to get the SYE installed over the course of about 12 hours (several trips to Sears and Harbor Freight were required because I'm a moron). Driveline vibrations are gone, except a very mild vibration when accelerating between 30 and 35 MPH (and a faint drone at 70+). Looks like I'll need to measure my driveshaft angles and see if I need to do some slight shimming.
Anyway, pics! I didn't document the whole process due to being somewhat pissed off the whole time, but I did snap a few pics.
While I was doing the installation, I did find some hairline fractures in both the front and rear halves of the transfer case:
There were additional hairline fractures appearing in the original tailshaft housing as well... I did put quite a few miles on the vehicle with these driveline vibrations (probably nearly 1,000), so I'm glad I got this done before any kind of failure.
How likely is this to cause long-term problems? I'm dreading the prospect of needing to get a new transfer case and having to move all this stuff over, as the oil pump did anything but "slide" onto the new mainshaft like it should have. Even with the teeth lined up perfectly, I had to tap it on 1/10th of a millimeter at a time with a hammer and screwdriver (light tapping, as heavy hits did nothing to aid the process). Fortunately, once in place, I managed to get the oil pick-up line fully seated into the pump, and the pump still rotates freely.
Let me know what you guys think.
*EDIT* Another note - my 231 only took about 1.5 quarts of ATF+4. Everything I've read states it should have a capacity of 2 quarts. Is this normal?
