I agree with Ed and Jerry, there has to be a seal of some kind in that threaded collar.
Some more pictures will be helpful.

FRank the difference is because up to 1954, one is the extended bed length 1/2 ton without carrier bearing and the other is a 3/4 ton truck with carrier bearing, in both instances they have a not sealed rear bearing housing on the sm420 that needs the torque tube bell/collar type assembly
