Re: 4x4 WON\'T WORK!!!!!!!!!!!!!
It's just a matter of tracing the power along the driveline, you're doing the right thing. So, you put the Tcase in 4WD high or low, and the driveshaft turns (has power to it) right? The next thing in line is the housing (carrier, gears, etc), then the axle shafts out to the ends where the ujoints and outer shaft are and then finally the manual hubs.
If there was a real problem in the housing, you would probably hear some kind of metal grinding, and most likely some kind of pop or bang. It is unlikely you put it in gear and then the gears just failed. Like Burned said, check those outer axle ujoints next. If you put it in 4WD and leave the hubs unlocked you should be able to see those turn. I also think you can reach in there and try to manually turn them, and they shouldn't turn.
If all they appears normal, then your last link is the hub and of course the manual hub dial themselves. It is pretty easy to pull these off, inspect them and the internal hub pieces to make sure the engagement action is happening.
