Every differential I've changed looks like mercury on the first change. That's a good thing, as the hypoid gears work harden there is debris generated. Resulting in contamination. Now if you are questioning the validity of the oil due to the contamination...I don't know. I do know cant be beneficial. Or maybe every differential I've encountered has impending catrostophic failure immediately after I sell it....maybe, don't know.
Like I said, cheap insurance.
If you don't want to change it don't.
