You have one of two things going on, either you have a broken axle or a blown up diff. If you can engage the CDL and the front shaft is spinning while the truck is not moving then it is in the front diff. How mechanical are you? Where do you live?

 

He lives in Hawaii.
Here is what you need to do, get all four wheels off the ground, put it in drive and see what wheels turn.
While in drive look under the trk to see which driveshaft is spinning.
If while in gear one driveshaft doesnt spin then engage the CDL and see if both drive shafts spin.
If both shafts spin while in gear and the CDL is NOT engaged then it is something with that axle.
If both shafts only spin WITH the CDL engaged then it is your transfer case.
You can get parts shipped to you from the mainland if you cannot find them locally.

 

Mike has it right. Either you have a broken rear axle or your diff is blown. Drain the fluid from your rear diff and see if there are chunks in it. I would pop off your rear cover and check the teeth on your ring and pinion gears. If they look ok, pull your rear wheels and pull the axles out. Check the splines on the ends. My bet is that your gearson your diff are eaten up.
