Hell the snout that I'm running on this Mustang and the AMX is the exact same snout used on the rear of a late 60's early 70's 3/4 ton dodge truck.
I think the issue is more of a seal failure out at the wheel, slinging gear oil all over everything, brakes, tires, the track. Could be a bit hairy if you didn't know it was happening. Just my thought.

I would agree with that line of thinking.... that it's more of a seal issue... and that the bearing GREASE doesn't liquify at high temps the way the gear lube does.... so keeping it "in check" isn't as much of an issue.
All the hubs on my semi truck and trailer are oil bath.... and I run down the road at 58,000 lbs laden.

At first I thought it was just because the Moser axle wasn't polished at the seal surface area. Had a machine shop put the axle on a crank polisher and make it shiny. Got what the O.D. was supposed to be from Speedway before polishing, to be sure I didn't make them too small.
There is not enough inside diameter on the IMSA snout to fit a seal out at the wheel. The 2.5" Grand national snout does also have a outside seal. I just didn't like how close the wheel bearings are together on the GN style. The extra seal is a definitely an advantage though. Wouldn't stop the center leak but should keep the oil out of the wheel bearings.
Hoping this new style seal fixes the problem. Had the car out yesterday, did a Pro Mod burnout across the Conowingo Dam, car is so fun to drive.

I could see that the diagram made it APPEAR that the seal was nearer the carrier.... and that was why I asked -- because it didn't appear to be installed from the hub end... and I thought --- MAN! Ya gotta drop the pumpkin to install that and maybe it just looks that way in the drawing.
