    15/16" = 23.8mm so I'm sure either 15/16" or 24mm will work . . . it prolly depends on how much the hex is corroded.

    when I go to replace the transfer case and rear differential fluids... do i need to replace the gaskets? how did you guys pour the fluid into the it? I guess a pump jug?

    should I change the front differential fluid when I hit 60k? I dont tow much... I like to go off-road right on the state's property here and there

    Use a Gear oil pump. It attaches to the gear oil bottle, and you just pump it full. Usually, the gaskets are good for another round, but its a good idea to have fresh ones on hand, just in case.

    Yes. Get the OEM gaskets from Toyota.

    I belive the ones for the diff and transfercase are crush type gaskets. They only have to be changed every 30K, so I think its worth the extra $$

    no, the oil drain plug gasket was a dollar... I dont know the ones used for the differential or transfer case... probably more? they love making money on parts! Is the american way!

    Yep,
    It has the additive.. I used Redline 75W90 gear oil in both diffs and transfer case. No chatter at all in rear diff. As well as Redline MT90 in my tranny.. Good stuff.

    so I just want to make sure... 2 quart in the transfer case and 3 qt for the rear differential? I'm going to do it when 30k comes... which is soon. I'm not going to do the front since I dont do towing much and only run the 4x4 here and there....
    I have amsoil... since I have locking rear... they told me that I dont need the additives... the
    $29 75w-90 Synthetic Gear Lube - 1 Quart (Pack of 2)
    75w-90 already has it... :)

    I can't speak for the transfer case, but as far as the rear end went...

    It didnt take the full 3 quarts, there was probably a 1/4 quart left when it was all said and done. (don't quote me on that though...)

    I think I read somewhere in this thread that the change should be done at or around 30k, but what if I don't tow anything or even used 4x4 yet ( I know, I need to get out more) should I even bother? I've got 23k on it right now.

    It's not that hard. Pretty much the same as the rear diff, except the fill/drain plugs take a 10mm hex instead of a 24mm socket. The amount of oil the front diff takes is in your owners manual.

    If you have the TRD Offroad package, you will have to drop the *rear portion of the engine skid plate* to access the front diff. This *only applies to TRD Offroad Trucks*. Non-TRD's with the skid plate do not have this rear portion.

    If you do need to drop the rear portion of the skid plate, you will need a 3" ratchet extension...two of the bolts holding the rear portion skid plate on are in recessed placements.
