Inner and Outer Seal failure- Rear end- 64 Plymouth

[Butch Edison <waedison@xxxxxxxxxxx>]

Okay, so when I went through my 64 Sport Fury I got a couple of years ago, I rebuilt the rear brakes, put in new rear axle bearings as well as the inner and outer seals. The seals I put in leaked, on both sides, ruining the brake shoes. I had a difficult time installing the inner seals even though I have what I think is the correct Miller driver # ?-839. After ruining a few inner seals, I thought I got it right. While taking it all apart today, I don't see any apparent problems with the seal faces. 

So, I've taken the rear axles out to take a look. when I pulled the first axle, I got about 2 cups of rear end oil on the ground. I see that the oil is sitting level with the bottom of the seal as it sits in the axle. In other words, the axle tube is full of oil up to the bottom edge of the seal. Did I simply overfill the rear end when I refilled it? The SM says the rear end takes 4 pints, but what does that look like from the end of the axle tube ? I used what I thought was the correct rule of thumb when filling it, filled it till it touched the tip of my finger with my finger in the fill hole, bent at the first joint. 

Second, how does the large bearing at the end of the axle get it's lubrication? Is it supposed to be bathed in rear end oil, which doesn't sound right, as it's sandwiched between the inner and outer seal. Am I supposed to pre-grease it and it stays lubed with that, or is some oil supposed to get past the inner seal and lube it. 

Hope these questions are clear. Thanks/Butch
