My jeep got flooded during the hurricane - water got in through the diff, mixed in with fluids, created a milkshake of crap that started leaking out of the rear axles. Took out the axles, replaced bearings, oil seal and retainer - going to reinstall but noticed there are seals on the inside of the axel tubes. Everything I’ve been reading about Dana 35 (no c clip) - there are no inner seals. Here is a picture of the driver side inside the axel tube.What is this? On the passenger side, there is the same thing and it was rubber on the one side. Any insight would be greatly appreciated!
