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?
You've confused these fluids with automatic transmission fluid advice. After a lot of miles many people feel that a fluid change in an automatic will break crud loose and cause problems. A differential and transfer case work much differently than an automatic transmission and there is no danger whatsoever.
Do it, you car will appreciate it.
