Micksurfer,
Can you post the image so we can see it on this site? WW2 Chevy military 1 1/2 tons (1940-45)have an outside oil seal that sounds very similar to your description. Does the outer seal press onto a bearing lock nut and seal on the inside of the axle flange? WW2 military truck manuals call for greasing the rear bearings while single speed civy trucks do not. I have no experience with two speed rears. The basic design and parts images appear to be VERY similar and has been hotly debated on military restoration sites. I have taken apart several military rear axles, and the seals are there but they have not functioned for long periods, and the bearings are lubricated soley by gear oil. Oddly enough, the bearings all looked servicable. It would be interesting to see if it is the same part as military trucks used a GM corporate banjo axle and some parts appear to "taken off of rack" from civy production.
