Check out this break! Looks like its cut right in half with a laser.
I say it's a defect! What your opinion? Every other axle shattered.
This one and where it broke inside hub assembly without breaking
unjoint which by the way is a Yukon 760 super joint!
Would like to here from you all.
Failure analysis is a branch of steel metallurgy a guy can spend their
life learning. Seems easy from the outside but quickly gets involved
when you get into it very far.
I know just enough to get myself into trouble. ;)
That looks like to me a fatigue failure, and it being chrome-moly
steel makes me feel like they ain't heat treating 'em worth anything?
What's weird is how Dana's people are like experts at heat treating tho.
If your particular setup allows (makes?) the shaft bend with every
revolution then there's where one problem is. Can you fix that?

ps- Heli's post showed up while working on mine. Wow that would sure
explain a lot about "Dana's people" -if- the axles were basically out of
