The diff cover is made out of soft aluminum. No rational person would conclude some abrasion to soft aluminum would be responsible for the break of a steel high-tensile strength 10.9 bolt.
Yeah I saw it. The circled part looks like a chunk came out. Maybe it is the angle or the flash? I don't recall my diff ever having that kind of visible damage. I know it hangs awful low, but you hit something alright.
I may have missed this... why not try an insurance claim via some road hazard situation?
