Thoughts on rear diff fluid color after 10k?

[bjl95mustang]

So the other day I noticed my diff was about 16 oz low so I topped it off. Washed down everything and no visible leaks. But the fluid didn’t look the best.

So I changed it out today and this is what it looked like with less than 10k on the truck.

The front looked brand new as well as the trans and transfer case. However the transfer case was low too.

Looks pretty normal for the first change to me.

I dumped my rear diff fluid around 2k it was very dark also

Yeah, that’s about normal
I’ve always changed fluids the first time very early. A lot of heat buildup and discuss this year happens from the components breaking in. Not to mention the amount of small debris that is created.

Oil is cheap, components aren’t
