    Looking to swap the fluids out. I am a former seadoo tech and have always been a big fan of OEM parts. That being said its time to change out the fluids on my front and rear diff on the 2014 tundra. I see 75wt being the gear oil spec.... 75/85 and also 75/140?

    Do these come with LSD additive?

    anyone have the part numbers and capacities?

    Thx!

    No need for "LSD additive" since the 2.5 gen Tundras don't have a traditional limited slip differential.

    While it’s expensive, i recently had both diff and trsfr case done with toyota oem oil and noticed a 2mpg uptick. I also had air filter replaced, trans drain & fill, and added one bottle of lucas fuel system cleaner for a fair evaluation of everything done.

    The dealers I spoke with about changing the front, rear and differential they all said they use 75-90 unless it a warranty repair. I changed all of mine with 75-90 synthetic. I have had no problems going into or out of 4 wheel drive.

    If it must be OE, then 08885-02506, which is 75W-85 Differential Gear Oil LT.

    The LT gear oil is a little more reasonably priced at $33 per liter at my local dealer, as opposed to the LX gear oil which is much higher. It is used for limited slip differentials.

    If your 2014 is 4x4, be prepared for sticker shock when you ask about the Toyota Genuine Transfer Gear Oil LF at the dealer.

    75w90 from Walmart in front and rear. Only one you need OEM for is the 75w transfer case.

    Did you supply them with the oil? Every dealer i have seen just uses bulk 75w90.

    You might check out this link for a complete diff/transfer case fluid replacement using Ravenol. Much cheaper than OEM (especially the TC oil) and meets Toy specs. While I haven't done this yet (I'm barely at 30K) I will use Ravenol when the time comes. I'm just not looking forward to having to remove my cat plates to do it.
