2006 H3 Manual transmission

Was driving down the highway and the truck dropped out of gear completely on its own. It was not a good sound. I pulled over and now when I put it in gear and press on the gas, the engine revs up but does not move. I tried every gear including reverse and nothing. I then pushed the 4wd High Lock button and the truck drives and moves in every gear including revers but there is still a terrible sound coming from the front end, especially when I make a turn, the truck almost comes to a stop and bogs down.

Anybody have any ideas?

 

Front diff or 1/2 shaft is blown. That's why it will move in 4hi lock.
