One piece axle leaking gear oil

[Cj7355]

I recently noticed while laying under my jeep that there was oil on the inside of the rear tire, pulled the tire off and the brake shoes and backing plate were covered in oil. So i then unbolted the backing plate and pulled the axle out, the tube had oil in it. It had an inner seal in the axle tube followed by a spacer and what looks to be a bearing race pressed into the end of the axle tube. My question is, is the bearing lubed by the gear oil? If so why is there a seal in the inside of the axle tube? I’m stumped and i can’t find any good info on this. The bearingm on the shaft is also a “cone” style bearing which is different from any other lits I’ve seen.Any help would be appreciated

Who's axle?
The Moser's use the seal to separate the oil from the bearing and you pack the bearing with grease.
I would be pull'n the other side also.........

i can’t see any brand name on the axle, cleaned them up and nothing. I wasn’t gonna pull the passenger side until i get this figured out. The passenger side isn’t leaking. All I’ve seen anywhere else is a sealed bearing being used, not sure if the owner before me just used the old cone bearing an pressed it on the shaft or what’s going on. Only thing i can think is the inner seal in the axle tube is bad, allowing oil past the seal/spacer and race into the bearing and out the tube *

There is also an outer seal, just behind the brake backing plate. As long as this seal is good, you won't have Leak. In fact, some axles (such as the 86 CJD44) don't even use an inner seal. And some people drill a hole in the inner seal to oil the bearing.

But you also have to seal between the housing, outer seal plate, and baking plate.
