    So I had a quick question regarding our drivetrain. I was recently told I need to change my diff fluid and I didn’t know what axles/diffs our 2nd Gen. Tundras run. My thought process is if I could upgrade to an oversized diff cover when I go to do maintenance now would be the time to get things ordered. I haven’t come across much information in any of my searches except for talk of welded covers. Any help is appreciated. TIA.

    You won't be able to add an aftermarket cover because the rear of axle is welded, the third member comes out the front of the axle. As far as diff oil change, it's super easy, just make sure you can get the fill plug loose before you drain all of the oil. Depending on what motor your truck has the 5.7L will take 3.8 quarts in the rear or 4.9 quarts for the 4.6L. Front clamshell I believe is 2.25 quarts

    I really appreciate the information! I have a 5.7 and I’ll be sure to crack the fill plug before I drain it. It’s a shame that Toyota went that route with the driveline.

    No problem. You’re going to want a pump for the front diff but the rear you can just dump the bottle into it.
    I know, my thoughts exactly!

    The front diff can be a real pain in the ass. For some reason you need an allen, 10mm I believe, and they can both be really hard to get off. Make sure you get the wash kit for both of them. Mine had no washer on the front and I think this made it harder to do. I had to pull the torch out and heat it up to get it to break free. The impact gun could get it loose. Plus, I let it sit in PB blaster over night. Look it up. I ended up having to replace the drain bolt on mine. Toyota usually has them in stock because it's such a problem.

    Toyota's design is actually kind of nice in some ways. When changing the gear ratio or installing a limited slip you can put it on a bench and set it up vs doing it in the axle housing under the truck. Also if you run out of oil because a seal blew you can buy the center section from a junkyard and just swap it out. I'm not sure if there's any advantage to having more oil capacity. The oil leaks tend to be from the breather getting plugged and pushing the oil out past the pinion seal. I don't think I've seen any other failures than that.
