Default Crimped Bearing Race

I was changing out my front axle seals on my Dana 30 and noticed these marks upon inspection. 4wp installed my gears, I'm guessing he over torqued the bearing caps to Dana 44 specs.

This was 50k miles ago. Should I be concerned with anything other than premature bearing wear?

The Dana 44 torque is almost 2X the Dana 30 torque. I wonder, if they had done that, if some threads would have been stripped. Although, the bolts are the same size, according to the parts book. That kind of eliminates an over-torque issue.

A possibility is the caps were not installed in their original positions; left and right, and/or top and bottom.

Are the marks on the inside and outside of the race in line with each other?
Is the mark on the inside rough?

Yes they are inline with each other. And are on both the top and bottom.
I don't know how to describe it, but looks like the bearing grinded it smooth
