Typically the C&C axle isn't even the same manufacturer as the regular dually and single wheel axles so I doubt you'll be able to swap any internals. If there's water in the housing then the bearings are surely shot, and the gears are probably hosed, too, they get weird little rust tracks/scaling on the faces of the teeth.
The very first thing I would do is drain it to see if there's water inside.
