    Im doing my 30k maintenance and went out today to get all the things I need. However, I cant find the rear diff oil 75W-85 anywhere. I can only find 75W-90 which is recommended for the transfer case. Would I be able use the 90 for the rear? Any info is appreciated.

    I just put Mobile 1 75W-90 in my rear diff yesterday. It was one of the recommended oils in the rear diff oil change DIY how-to thread in the technical section.

    A lot of people use 75w90 without issues. The 2nd gens first spec'd straight 90w, then it changed to 75w90, then later 75w85.

    Basically the only 75w85 GL5 choices are toyota's diff lube LT ($30+/qt) or redline ($15/qt).

    Personally I have the redline stuff in.

    Some stuff. Not a lot, just some.
    You'll be fine with the 75w-90
