There is metal to metal contact that has caused flakes of metal to come loose. Some flakes are to be expected in a rear end. If you feel there is an unacceptable amount of metal, pull the rear cover and inspect for worn/damaged parts. Refill with gear oil. Don't forget to add some friction modifier if you have limited slip.

I pulled the cover off today and looked closely at the differential components. There was no visible damage and no metal chunks to be found. There were some almost microscopic particles in the old oil but not a significant amount: probably normal wear.
While the cover was off, I tig-welded a boss onto the outside of the cover then drilled and tapped for 1/2-20 to fit an oil drain plug containing a magnet. The plug is located out of the turbulence of the ring gear. I will reassemble tomorrow and drive it for a while. Will pull the plug in a couple of thousand miles and check for particles.
Thanks for your input.
