Same thing happened last year on my MGA. The piece looks like a combination 
of bad stress design and eventual metal fatigue. Given that a good machine 
shop can make something as complex as a crankshaft out of billet, why would 
it be so difficult to machine a part to match this out of a modern metal, 
maybe with a bit of redesign to cope with the much higher torque than these 
axles were ever meant to handle?
