I was dye checking front hubs for a while in the late 60's and early 70's
after breaking a hub at Summit Point, tearing off the left front fender, and
twisting up the original, optional, light front sway bar that ran under frame
like a pretzel. I actually did find another couple hubs with surface cracks.
As Bill would know, radiographing is used in Nuclear Plants for checking
stainless steel piping and welds. My guess would be that 95% of racing part
failures result from fatigue, which start with surface cracks.
