    I've looked all over and am probably just overlooking the obvious, but is there a reference guide to fluid changes?

    My '14 just hit 30k and I like to do the f/r diffs, xfer case and tranny along w/ the plugs.

    I'm just not sure what gaskets, tools and fluids/quantities I need.

    Also, anyone doing the ps fluid and/or brake fluid on these trucks? Since mine is 4WD and has the ps assist brakes, I figured it might be good to get some new fluid in there.

    I change the brake fluid out (just syphon/fill the master cylinder to introduce some new fluid) every 30k and it's got over 170k on it w/ zero problems.

    For the diffs and tranny/tcase, there's a sticky thread. Did mine about a month ago. Used 8qt total of Amsoil SevereGear 75w-90 for everything. Haven't done the brakes yet or PS, so I have zero input there lol.
    Changing the fluids was easy and straightforward, just use PB Blaster on the fill plugs so you don't round d off anything. Also if you have a fluid transfer pump, it will make doing the tranny and front diff much quicker

    Should've mentioned I have a manual transmission. So for both diffs, the tcase, and tranny - it took about 8qt.

    Toyota says my truck uses:

    Toyota Genuine Differential Gear Oil LT
    75W-85 GL-5 or equivalent

    The note below this says:

    Your Toyota vehicle is filled with “Toyota Genuine Differential Gear Oil” at the
    factory. Use Toyota approved “Toyota Genuine Differential Gear Oil” or an
    equivalent oil of matching quality to satisfy the above specification. Please
    contact your Toyota dealer for further details.

    So I figure as long as it's 75W-85 and GL-5 (or equivalent, whatever that means), I should be good to go.

    I started researching and found out that this is a synthetic oil as well.

    The Toyota part number is 08885-02506 and the cheapest I could find it for is around $35 per liter. So 6 or 7 quarts worth to do my front and rear differentials and the transfer case would cost a lot.

    Red Line sells a 50104 which is a 75W-85 and it meets GL-5 specifications (and it's synthetic). I found it for about $17 per quart which is a lot cheaper than the OEM stuff.

    I prefer to use OEM on Toyota's, but I can't afford almost $200 for gear oil every 30k miles.

    I just use conventional (and generic) 80W-90 in my '02 and it's gone 170k miles without a single issue, but everything else except air filters gets OEM on both trucks.

    Anyway, just thought I'd update and let y'all know which route I went and why.

    Thanks for the help!

    There's lots of threads on here about this. Search the DIY thread, very simple procedure...most guys use the 75/90 gear oil, either synthetic or regular. Buy it at any Walmart or Auto parts store. Should run you around $80-90 for 6 Qts synthetic. You don't need to use the stuff that Toyota recommends, way too expensive and unnecessary.
