Joe:

Have you tried a different type of seal?

Years ago we changed from plastic lip seals to an older leather
spring-loaded type which gave better duty on a truck axle.

Second-source parts places can often give you a dimensionally similar
seal with better performance.

Moving the seal a 1/16" in or out can allow the lip to run on a fresh
area on the axle tube, that can also improve seal oil retention. We
did this on some Scania rear main seals that wore a groove in the
crank end, and a new seal just sat in the same groove, so a move
helped to find a new wearing surface.

Last thing:  Putting a new seal face in the form of a sleeve onto the
axle tube can help, especially if it is a thin sleeve held on with
loctite so you can get it off again if necessary.
