So whoever went to the expense of having these axles made likely had them hardened? Todd

The only thing hardened in my earlier diff's life were the criminals that customized the axles!!! My custom "narrowed" shafts were turned from the original shafts... and were not "properly" hardened. At least that's the prognosis of NWD. That is why mine twisted so far before it snapped.

You cannot determine hardness by eye. A machine shop that has a hardness tester should be able to check it for you (preferably a sonic type so you can measure the spline area without marking).

Bish is right about the damage done at failure. That's how my bill got so frapp'in big.... oh, not to mention sitting road-side for a couple hours whilst cars went by gladly honking at me (har-har-har) as they went by.

Ummmm. I'm thinking new 31 tooth'ers. But, your money is easier for me to spend than mine!! (I had NO CHOICE)

Happy decision time!!!
