Over my 50+ years in the hobby I've seen that type of failure may 5 or 6 times, and more often on Chrysler products than Packard, not that that can be statistically significant.

I've no real knowledge of metallurgy or failure analysis, I always attributed it to a poor fit between the taper of the shaft and that of the drum. PS - I'm reminded that what at least two of the failures had in common was the use of a lubricant or antisieze compound on the taper.
