Meh, ain't no biggie. I have a 2020 with 156k miles and has yet to have the pumpkin oil changed. Or the tranny for that matter. Then again, she's a road queen and hasn't seen mud in at least two months.

I’d change the diff oil for sure. That’s a lot of miles, road or not.

I might have missed it and am definitely too lazy to look it up in the manual, but when should the diff oil be changed? I'm at 26K miles and live in the desert.

I will do it for you but I want a finders fee.

For a new vehicle that is used as a daily driver (no off-road use or trailer towing), a very good service advisor at my selling dealer recommended changing the differential fluid in both axles at 30K mi. After that, I believe that the guidance from the dealer, for a daily driver, is every 60K mi.

Also, the book says do an inspection at 20K mi.

For severe duty, the book says change the fluid every 40K mi. Others have already commented in on this.

In practice, the rear usually needs to be changed more often than the front.

Info pieced together from the owner's manual (not much help for a daily driver):

Appreciate that. I think I will do it at 30K miles.

Annually or every year, which ever comes first.
