about differential and transfer case fluid replacement

My 4Runner 4wd is already 122000 miles and differential and transfer case fluid not changed. It still drives like a dream.


I heard that if you change the fluid it will hurt your car more since those fluids never been changed since.


Is that true?

    Have you read your owners manual? What does it say under service schedules? Whatever it is I expect you are way past due to change both your diffs and transfer case. You should likely be coming due to change both for the 2nd time!
