    DIY: Change the Rear Differential Fluid on '07 Tundra w/pics



    Spurred on by mhadden's great thread on changing the oil, (and thanks to daless2 for some additional info) here is a "how-to" for changing your rear differential fluid.

    Supplies Needed:

    4 quarts of gear oil. Toyota calls for the following spec on the Differential Fluid = LT 75W-85 - GL-5 rated but 75w-90 will do. I chose Royal Purple because it comes with the no-slip additive already in it. How much Differential fluid you will actually use depends on what model truck you have, RC, DC, CC, and if it is 2 or 4 wheel drive. Also note that the Tundra has a "wet axle" which means fluid goes down the legs to the wheels.

    In all cases it will be between 3.6 and 4.0 quarts.

    15/16" socket.

    A way to get the driver's side of the vehicle up so all the fluid drains out. The safest way would be to use one of the metal ramps and drive up on it. If you plan on using the truck's jack, you will need 2 bricks so you can get it high enough. More on that later, but you know you should never work under a truck supported by just a jack, right?

    Towels.

    Oil catch pan.

    A warmed-up truck. Drive around and get the truck to normal operating temperature. Park on a level surface, wait about 10 minutes, then begin.



    STEP 1:

    (If you're going to use one ramp on the driver's side, drive on that now before you empty your oil out. If you're going to use a jack, wait to do so because the force of you loosening the bolts may make a dangerous situation even more dangerous)

    Loosen the FILL BOLT. Always loosen the fill bolt first. What if you loosened the drain bolt first and then couldn't loosen the fill bolt? You'd be empty and out of service. Put the fill bolt somewhere you won't lose it.



    STEP 2:

    Place your oil catch pan underneath the DRAIN BOLT.



    STEP 3:

    Loosen the drain bolt and allow the oil to drain out. Give it some time to drain properly.



    STEP 4:

    Inspect and clean your DRAIN BOLT. It is magnetized. At 1000 miles on my truck it had a bulbous gel-like goo that was black and full of shavings. Clean that all off and place somewhere you won't lose it.



    STEP 5:

    Jack up the truck so all of the oil can drain out. I used two bricks since the stock jack isn't long enough. Notice I said do this now because if you do it first, using a lot of force to loosen the bolts could topple the truck. NEVER WORK UNDER A TRUCK THAT'S ONLY SUPPORTED BY A JACK. It isn't safe.



    STEP 6:

    Screw back in your DRAIN BOLT. Hand-tighten and then use the ratchet.

    STEP 7:

    Fill up the differential until it comes out of the fill hole. Tighten the fill nut by hand then use the ratchet.

    Torque Settings

    The Fill Plug has a torque setting of 36 Ft/#ís

    The Drain Plug torque setting is 29 Ft/#ís

    Toyota does recommend installing a new gasket on each of these plugs. I doubt you will have to however.



    STEP 8:

    Clean up and go find an open parking lot and do a bunch of figure eights. This is to get the gear oil to all the parts.

    STEP 9:

    Park on an even surface, unscrew the fill bolt again and check the level. Top off if need be. Replace the fill bolt and you're done.

    I hope this helps. I take no responsibility for any damages to you or your truck for following this. I suggest you always take your truck to an authorized Toyota dealer

    Two house bricks? And the factory tire-changing jack? Doing this in pinch is one thing. But to photograph it, recommend it in a maintenance procedure and put on the web is another.

    That was clearly an OSHA violation. A great DIY tho.

    This is great and I'll be using this one soon. Anyone know if there's a DIY for the front diff. on 4x4? Thanks

    Did mine wiseguy, but don't have any pics. I can tell you it is much, much tighter than the rear differential, both in getting the fill plug out and once drained, refilling the differential. There is no room to fill the differential directly from the gear lube plastic bottle so I ended up using an 24" or so 1/4 plastic tubing to connect to the bottle of gear lube and running it from just inside the fender well over and between the front suspension and into the fill hole. You can squeeze the bottle of gear lube to accelerate the process of filling the differential. I suppose if you had an oil/gear lube hand pump it would make the job much easier.

    I have a hand pump used for my boat's lower unit. Worked pretty good to get the oil up to fill the front differential and the transfer case. The rear differential fill hole is pretty easy to get to.

    for the people interested in doing this yourself...... i would not recommend jacking up the drivers side of the rear end to get "more oil to drain out". if you look at your drain plug location, it would make sense that more would drain if you jack up the divers side......but that is not true. i had mine jacked up, let it drain until i had no more drips......then let the jack down and another 1/4 - 1/3 quart of fluid drained out.

    the oil does not just sit in the round "pumpkin" part of the axle. it also goes out to the left and right sides for a ways. this is why jacking it up will do nothing for you.
