Default Diff fluid change: It took 3+ quarts ?!?

Yesterday I changed the diff fluid. I put in all three quarts; I thought it was only supposed to take 2.85 quarts? I'm pretty sure the car was level.

The fluid that came out looked like molten silver. No chunks on the plugs, but lots and lots of that 'paste' (fluid+filings) was stuck them. I suspect it was the original fluid from 2014, with 75k on it.

Presumably, if the gearsets were worn enough to allow more fluid to fit, wouldn't I be experiencing other issues, like whining, excessive driveline lash, etc?

I put very close to 3 pts in my 2017. I also let it drain for close to an hr . wouldn't worry

That’s what mine took last fall, what was more surprising was there wasn’t even 2 quarts in there from the factory.

+1 to not worrying about it. To appreciably change the amount of fluid it would take would require having the car very visibly pitched forward.

Fill 'til it dribbles, cap it off, send it. It's warming up, go drive!
