axle tube seals

[ironman_gq]

Would there be any problems if I put seals in the axle tubes of a model 20? i have tube seals in my front end and I am having trouble with the seals on the rear leaking. I am thinking that if I put seals in the tubes then I can just pack the wheel bearings with grease and not worry about oil leaking into my brakes. the seals Im looking at are made by seals it

I don't think there's room for that kind of seal in an AMC20 axle tube. Just FYI, there is an inner and outer seal in the 20 from the factory. They usually don't leak unless the diff is over full, the housing is bent, or the sealing surface is corroded.

The inner can be swapped by pulling the axle/hub/bearing/backing plate as a unit. The seal sits behind the bearing. Replacing the outer requires separating the hub/axle. That's best done by taking the entire assembly to a machine shop. I've seen them stall a 20 ton press. If you replace both seals and bearings, you should be good for another 20 years (providing everything else checks out).
