so this an interesting subject. as i once purchased a used 2006 jeep with very low miles.
question! is this an inherent design flaw?
is it due to the forces , vibration, excessive wear, not robust enough to prevent radical vibration.?
I had two option complete rebuild of the front end with...
H925 according to the spec is equivalent 38-45 Hrc , this is the approach I would take, make the test specimen same as the wall thickness, after heat treat machine to correct size for testing. that hardness is easily machined with out compromising. run the parts with test specimens.

That is ridiculous. Find an other supplier.
Get 3 quotes. And the part about stressing the coupons is nonsense. What is the wall thickness of the casting. Plus what is the time and temperature. , what pops in my head one hour per inch.
