Transfer case gear oil change

[psfod3]

I have a 08 Rogue with 106,000 miles on it. I mainly drive highway miles and do not tow anything with this car. I changed the cvt fluid at 80,000 miles just to be on the safe side. I have never had the transfer case or rear diff gear oil changed. The dealership does not really push it as they push changing most other fluids. I have no problems with the car other then totally warped rotors. The question I have is it to late to cange the gear oil at this point. As I never changes it in 106,000 miles could draining it cause something to leak . I have always heard that some times dirty fluid in old trannys may be what is holding it together. I dont know if this appiies to transfer cases and differentials.

Change out the fluid in your t-case and diffs. You'll only be doing them a favor by evacuating all the break-in wear and any crud left over from the manufacturing process. The next time you drain the fluid, it'll be much cleaner than the factory fill was for that very reason. The factory fill in my Pathfinder's rear diff was replaced at 123k miles and 11 years and I have no issues at all.

nope, you can change the gear oil in the transfer-case and rear differential at any time. they dont have clutch-packs like transmissions do - so removing old fluid, and adding fresh new fluid will not cause them to slip. and 106,000 miles is still very young for a Japanese car.

my suggestion is to change the transfer-case & differential every 30,000miles. if your gentle you can easily go 50-60k and do the changes. you want to remove the metal shavings inside, and clean the magnet on the drain plug. its gonna be filthy at this point. mine was changed at 30k-sih, and was filled.

if you would like to see how its done, here you go: (i did the work myself, and have pics to show)
