1-ton axle seal replacement

[Konk]

I was hoping to get around to this a few weeks ago, but a few unaccepted priorities popped up. Seems like I should be able to get to it this week and I wanted to know a few thing before I started to tear into it.


Truck was an old 1-ton work truck for my previous employed and the seals were replaced around two years ago and the truck probabally hasn't even rack up 100miles since then. When I did the wheel cylinder on one side I skipped the seals since they're so new, but after a drive on the interstate (probabally the first time that truck has been over 50mph in atleast a decade) the axle started to leak on the other side. At first I thought the other wheel cylinder went out, but this is definetley axle fluid.


Do I need to remove the drum to get to this seal, or can I swap it for a new one by just removing the axle shaft?? Are they're multiple seals for the full-floating axle or just one?? Trying to get some info before I tear into it, thanks!!
