Rear diff metal shaving

First rear differential change at 56k found chunks of metal on plug. Any advices what I should do?

 

Unless it's making noise or feels weird (vibration or binding) I'd just send it, but I'm kind of a savage.

 

Completely that^ For all you know those pieces fell off 55k ago and it's been fine ever since. I wouldn't think twice about it, in fact I had gears the other day with way more shit wrong and I put it back together and test drive felt great so I buttoned it up.

 

Normal shavings for the initial fluid change, lot of threads on it.
Typically it's milling debris from the diff housing

 

I’d say Normal I got my truck used but new to me and instantly changed fluids at 28k I had some wicked pieces. Never gave me issues out till 72k miles.

 

Had the same thing when I changed at 40k. Seems to be pretty common on the first change.

 

Good to know thanks for the replies.
