    I relocated the rear diff breather and was wondering if anyone knows where our front diff and Trans breathers are located. In the FJ they are in the engine bay and pretty easy to locate. The 1st Gen. Tundra vented both in the engine bay as well. I can't find 'em in my truck.

    They likely are, but they were not as obvious as they are on the FJ, so I didn't see them. I'll take a better look. In the mean time, if you find 'em, holler.

    They sure weren't very obvious. Thanks again. I think they're high enough that I don't have to mod them like I did with the rear.

    No you should be fine. There are much more important things to worry about if you go that deep in water, like the engine. Diff is cheep in comparison to a new engine :)

    I *try not to go in water deeper than the frame. The rear diff breather wasn't well placed for that.

    Good idea. Soaking interior wouldn't be good either. Agree on the rear breather location being on the axle however lets discuss how water would get in.
    From what I know, the axle would need to be hot enough that when it hits the cold water it will cool quickly pulling air or water into the axle to make up that space difference. How hot does the axle need to be? How quickly does it need to cool? How much volume is displaced? Does a little water really cause any problems if changing gear oil on a reg basis?

    From everything I've read and discussed with some buddies, you're correct with how the water would get in. How much would get in? I don't honestly know. But it would seem anything other than condensation would be bad.

    How frequently do you change your diff oil or transfer case oil? I use Mobil 1 synthetic gear oil and I go about 30k between changes. Honestly, the transfer case always looks clean. The rear gets pretty dirty and the front not so much. My previous two Toyota 4x4s have always had really clean xfer case oil too. Not sure why but it seems to be a Toyota trait.
