Well the more I roll this over, the more I realize what I missed...
Upon disassembling the troubled drum, I did notice the axle nut was acting on a pair of stacked washers that had been carefully welded. I see now that this was an attempt to "tighten up" the drum on the axle at some point and this should have been my first clue to look further. I'm guessing to me the drum seemed firmly connected up in the air but actually had some play when in action on the road that had been ovaling the hub over time with only the square key transferring rotation.
Another clue was a munched outer seal that I now see was getting beat up by the tip of the hub reaching deeper inward than in should have. This explains why that side was pretty soaked with 90wt. (Gotta make sure I don't forget to top up the diff when everything's buttoned up. What's the favorite gear oil to use in the rear end?)
I have a replacement hub in the works thanks to a member here so I expect to be rolling & stopping in no time. Thanks again to this group and to my buddy, Jimmy, for his jumbo drum puller! I've put that beastie into action much more than expected.
