Devin,
You are correct. The seals at the end of the axle tubes are grease seals for the bearings and the diff seals are inside the axle tube next to the gear set. Gary Jones is using a different seal than the one I posted earlier in this post. I believe he got them from Coleman.
I am doing a winter tear down as well and replacing all seals and bearings and will post all part numbers later.
