    I found the threads detailing how to change the fluids in the front and rear differential as well as the transfer case.

    I have a 2012 Tacoma off road. Both differentials call for 75-85 gl-5 or equivalent. The transfer case calls for 75-90 gl-4or5.

    I can't find 75-85 can I use the 75-90 in the differentials as well?

    I ended up getting valvoline because it's the only brand that they had enough of. Next time I'll order online and get something else.

    If you have an Advance Autoparts nearby that has 6qts of the Mobil in stock, order online with code TRT30 (30% off $50+, good through 12/31/2016) and pick up in store. I got 6qts for just south of $50 all said and done. Best deal I was able to find, including a gallon jug + 2qts.

    I was thinking about trying to do my front and rear and transfer case myself. I have a 2014 with just shy of 30K. Is this an fairly easy job, im somewhat handy. Also, any videos on how to do it ?

    I plan on doing it. Is the job fairly easy ? I pulled up the how to threads on here and it seems pretty basic. Only thing i see if the plugs are tough to get off so as long as im careful and dont strip them i should be ok. Gotta get a fluid pump, they have it at autozone i believe and the oil and thats it. I have the wrenchs and the sockets. Oh, should get the torque wrench, harbor freight has one for 12 bucks. Hell of a lot cheaper this way i hope.

    ok will do. I also plan on getting the PB Blaster since that seems to make it easier to break the plug free. I appreciate your response bro, thanks. Im looking at going with a Tundra soon anyway, i have two kids they kick my seats and it drives me crazy. Need more room but not looking forward to the gas prices and fill up costs of the V8. Wish Toyota would have put a little more room in the 2016 but now that didnt happen so im looking at going to the Tundra.

    Yep, rear diff is the easiest IMO. The fill bolt has a really low profile (so it doesn't get bashed by rocks?) so it's hard to make the socket grab on. Make sure you've got the socket on straight or you'll damage the bolt. Hit it with a few rounds of PB Blaster.

    A tip for a stubborn fill bolt (what I ended up doing):
    1. Get a decent sized ratchet handle, I used a 1/2" drive for my 24mm socket
    2. Put the socket on the bolt so the handle is parallel with the axle
    3. Use a floor jack to slowly jack up the handle of the ratchet while holding the socket on the bolt with your other hand
    Going slowly, this will break the bolt loose.

    I did mine at 34K and the oil was BLACK. Transfer case was really clean (surprised me) and front diff was a dark brown.
