Got the rear brake shoes replaced today, as well as the oil in the rear diff (plus I collected a sample to send to Caterpillar for analysis). Just used red RTV on the diff carrier instead of a gasket. It seems to be holding up. You can tell the diff oil had never been changed. If not by the looks of it, then definitely by the smell.

Luckily my rear dif was rebuilt in 2010. Not sure of the miles, but it could not have been more than 35k ago.
