The Duchess Project: Rear axle seals leaking.

I picked up this comment from JW from an earlier post where I needed a new hub, and discovered I have 1801-A ambulance rear axles.

"Joe, JD beat me to the keyboard, but I fully agree with him. The rear wheel bearings should be packed with wheel bearing grease.

There are two oil/grease seals for each rear bearing:
One on the inside of the bearing to keep gear oil from getting on the bearing and keeping the grease from getting into the oil;

and one on the outside of the bearing to keep the grease from leaking onto the brakes and to keep dirt and moisture from getting into the bearing."

I noticed some oil bleeding across my left rear whitewall and figured it was a leaky oil seal. Not much was leaking through the outer seal, considering it's designed to retain grease, but oil was coming through. I pulled the hub and the bearing was covered is a light chocolate oil. I pulled the axle out a bit. The inner oil seal is not sealing.

So now I need to remove the inner and outer seals and I'll need replacements.
The outer one is rusted in place, so I'll let it sit. Hopefully it will have a number.
I'm looking at Part 12.0315 Shaft Bearing Oil Seal
The Packard number for 1801A axle Inner Oil Seal 323151 and Outer Oil Seal is 324961.
Bearing is Timken 3576 and outer seal is National 473473.

QUESTION: Will I have to take the axle to a shop to remove the inner seal 323151 and shaft bearing 324947 ?
