I have found the some thing on my 2 1/2 ton and 5 ton . my 53 GMC had no outer seals when I first got it. I replaced the old seals and wear ring and the missing seal also sealed the key way and 3000 miles later I pulled one a part because of a wheel cylinder and found gear lube in the hub enough to wash off the grease but keep the bearing lubed . I now have almost 7000 miles on it and have not had it back apart . I try to feel the hubs after driving to check for heat .
