I dunno how current light trucks are arranged (libraries no longer stocking service manuals) but for many "moderns" the diff oil had free access to the hubs and a single lip seal was all that contained (working on a precise surface not one worn by a felt!) Under good conditons it is remarkable how efective the seals are; many cars operate drenched in oil. However basic nitrile seals go hard with heat and age.
I did not know about viton seals. All the rear crank seals I had encountered on Javeilns were solid. So, inspired by the Seven, I fitted a slinger as "back up". It was so effective the nitrile seal soon destroyed itself from lack of oil! I had to periodically reverse fast and brake to stop the hissing noise!
