Axle Seal/Hub Thoughts - SteelSoldiers

So i'm in the boat other confused Deuce owners (newbies) but had some thoughts on what others are doing in the world of 4x4's, wondering about their application to these 6x6's.

I was out and about in the Deuce when I did what every responsible owner does and felt my hubs. The right rear passenger was a touch too warm for my liking. This is the same hub that the prior owner replaced a leaky seal on before he sold it to me.

When I popped the hub out, I had a nice glob (4oz) of Diff Fluid also come out - along with it turds of grease that used to be in the bearings - hence the likely issue that its the inner axle seal that has the issue.

This brings me to my questions/thoughts:
1. His Uncle (who replaced the seal) said "you need to park it on a hill overnight to make sure that the fluid gets into the axle housing after you swap it out." This seems a little lunatic to me, but what does everyone else think about this?

2. Obviously I need to replace the inner seal.

3. What others have been doing with full floating Toyota axles (like the deuce's) is putting a grease fitting outside their hub, and loading the hub/bearing area with grease as needed. My thought is that this would work to keep the bearings nice and lubed, heat low, and even if a little diff fluid mixed, it wouldn't be as big an issue (until time passed of course). I know it would take a lot of grease, but better than something catastrophic!

Everyone else's thoughts? Thanks! any full floater axle has the same design, take a chevy 14b for example, do you put grease in the hub bearings, nope, the oil from the diff housing will spill into the axle tubes, spilling to the hubs thus lubing your bearings, 2.5 ton toploader in theory the gear oil should be pulled up with the bull gear lubing it and the pinion setup, oil will travel down the axle shafts going through the spindle against the wiper oil will get into the bearings, but you have to heavy grease the bearings to keep that oil out, what can you say it was a old design While we are on the subject of rear axle seals I remember sombody here on SS posting somwhere about updating the rear outer seal( the one against the plate that the brake shoes mount to) with a seal that allows you to run with oil filed hubs.
I have used the serch but cannot find any info on what PN# the seal was or anything. Has anybody else tried this mod?
To me it seems like a darn good idea if you could seal the back of the hub so you could run with oil filled hubs and not have to worry about that seal under the spindle nut failing and washing the grease out all over your brakes,,,
