I remove the wheel today to fix a flat.. Found that I have 4 loose spokes, gear oil is on the inside of the drum. It looks like there is grease mixed gear oil. There looks like a outer seal , grease seal. Is there a inner oil seal? Or does the wheel bearing ride in oil? Where would I look for such seals? Brake shoes are light coated in a grease/oil goo. Never a easy simple job!
I recall just packing the axle bearings with grease and there being a felt inner seal to hold the gear lube back. See pictures below.
These are my local guys that can seemingly find any bearing or seal if it exists. https://www.cutter-sales.com/ Not sure where you are located.

I think the inner felt seal is bad. How hard was it to pull the axle shaft? It looks like my outer seal has been replaced.
I live South Dakota. I make trips to the twin cities a few times a year. I will need to pull the seals and take them on my next trip.
Did you replace the bearings and races? How hard was it to pull the races?
Yes, I had to replace the drivers side. When I got the car the outer bearing was toast, literally jacked it up and was able to pull the axle out with one hand. I used a slide hammer to pull the inner race out, outside one was gone. There were a few shims behind it. The seal you are after is called the "axle drive shaft oil washer assembly" Page 3-1 call out 26 group 3-F Part numbers 43049 & 600475 in the Plymouth Master Parts List. I had to have a machine shop press the new bearing on the axle. I pounded the new races in the axles tubes with a piece a wood I cut to fit. (precise I know) Slammed it back together until it felt and looked good.
Old one.

the rear axle has an oil seal and a grease seal.the grease seal is available but not the oil seal. I used a National Seal #204027.this seal is slightly oversize so I had a friend take .021 off the seal and it fit nice. I bought the seal from Motion Industries. Hope this of some value. regards Carson
Thanks for the replacment seal info. Another trick for the books.
I have a question crazydave, what did you do for the shims? Those look in bad shape.

I think I put them back in (didn't try and find replacements) Couldn't imagine how they would make much of a difference, they are extremely thin. And since I had no way to check depth I didn't get too concerned about. Maybe someone knows the proper method.
Sometimes I just stop and think, how would the owner have made the repair back in the 30's? Then assume I'm doing it as well or better :)
