Rear axle leaking

[blucar]

I clicked on the link that deuce lover posted regarding an earlier forum topic pertaining to the "quick fix" internal/external axle seals...
I am very familiar with this type of seal, I made a contribution to the 10'13-19 topic when it was active.
To recap, I have used this slip in type of seal since the 1950's, we always used a seal that was made by named National. I had several in stock which I used the last of in the late 1960's, they are still in my rear axle...
Replacing the inner axle seals is a huge job requiring almost a complete tear down of the rear axle assembly.
As I recall the Columbia axle required a larger seal, which has been out of stock for many years. The external slid in seal did a perfect job of sealing the axle thereby eliminating oil leakage into the hub.
