Jim,
I have had one break as well. I think metal fatigue is probably most likely. I was lucky they line failed in a parking lot albeit 500 miles from home. I changed it out the next morning .
Axle keyway and hub we’re fine . Just it’s time . It broke inside the housing and couldn’t be seen. Many times keyway stress from looseness can contribute near the key slot.

I’ve rebuilt hundreds of axles and che k them for stress cracks. You just don’t know.
Anyway, glad it didn’t happen on the road .
Replace it, check the other side.
All the best
