Spindle Flaw Defect Yes or No

A million years ago when I qorked on cars for a living,if a replacement wasnt readily available or affordable we would have heated the dull red with a torck and then filled the hole with a mig welder.
Then grind/file/emery cloth it smooth again.

It waa fairly common for bearings to fail and damage spindles back then. We fixed far more than we ever replaced.
