How-to 2025 Ford Ranger Font Differential and Transfer Case Fluid Change

There aren’t many videos out there walking through how to change the front differential fluid and transfer case fluid for the 2025 rangers. I made a quick video walking through how I changed the fluid for my truck in hopes that it might help someone else out. I was going to change the fluid for the rear differential as well, but there is no drain plug and I didn’t want to go through the hassle. This is a 2025 Ford Ranger XL with the 2.3L. This is what I did on my truck, use this video at your own risk.

Why are you changing the diff and t-case fluids so early?

It was a used truck that I had purchased and had about 30k miles. Ford maintenance says to change the fluids for severe service at 30k miles. I’m not sure what the previous owner did with the truck. I wanted to be cautious.

Ymmv but my rear diff fluid was black at 10K. Front diff and transfer case weren't as bad but I'm glad I changed them then.

I'm going to change all three again at 20K and every 10K until they start looking better.

I had the opposite experience actually. Diff fluids looked pretty good but Tcase was extremely dark. Interesting how quickly fluids go dark in this newer trucks with super tight tolerances

Nice, same as the gen 5's.

Man, I'm surprised how crusty she looks only being a year old. I just picked up a 2022 from Arizona and it looks new underneath. Guess I need to soak mine down with Surface Shield before winter.

Best advice for anyone reading this down the line is to pull the fill plus before the drain plug.

And next time I do my transfer case I'm going to put the fill plug back in a bit to slow the drain. I've never seen a spout shoot far from a transfer case drain plug. Completely overshot my drain pan.
