FWIW on the way up to Hurrah Pass yesterday Beno's rear FF decided to evacuate his 80. Spun all the hub flange bolts somehow...so they all need attention eventually. But at least the FF design can be dealt with in the field when it does go 'south'...

Took my none e-locker back axle apart to install an ARB, took lots of pictures and got some thoughts to add on PM for this rear bearing issue:
On mine the main area where rust has formed on both sides is circled in green. I think the problem is rust starting at the outer edge and because the studs are so widely spaced for that area the rust is able to push the surfaces apart which causes more rust ... If it goes on long enough then rust will build up round the o-ring and push that away letting water into the hub area and getting to work on the exposed retaining and ABS ring. Might be good PM for any 100 over a few years old to pop the rear hubs off and seal them up properly?
Looks just like the 200 series and 2nd Gen Tundra. They are beefy for a semi-float, but no service = no good when they go.
I have considered modding a bearing with a lube hole so a grease fitting could be used to purge out the bearing... not the best soloution though... too much grease in a bearing leads to more issues, those being seals and heat.
A FF conversion using front parts from the 100 might work....
