-Axles are 3/4ton corporate semi float 16 bolt. There is a detroit posi in the back and an Eaton in the front, the gearing in both axles obviously is 4.88:1. Both axles were bought from that truck yard out on the way to the playhouse on I-29 and then rebuilt by Eric at Ultimate Truck. They are indestructible and after it was all said and done it cost $5200 just for the axles.
-The transfer case is an NP203 full steel chain driven 4:1:1 low ratio, way better than it's sister the NP205 which is pretty standard on trucks, those have plastic gears in them.
