    Hey everyone,

    just went to the dealership to pick up the hardware to change the front and rear diff and transfer case fluid. Parts dude told me I only need what’s shown in pictures. Can do the front and rear diffs with that and transfer case doesn’t use any washers. Is this true or do I need to get something for the transfer case. Just don’t wanna get down there and drain transfer case fluid only to find out I need a new crush washer or something. Thanks. Don’t want any. Just reuse the washers comments. Not doing that. They’re cheap. I’m not worried about saving a couple dollars doing this. Thanks

    Can't help much but I'm related to one of the higher level technicians there. That's a good dealership.

    I would've thought the transfer case would use a washer but I can confirm that.

    Doesn't look like it needs gaskets with this style plug.

    The kits I had bought in the past were for "toyota" not Tundra specific. I wonder if I just didn't use the transfer case part number.

    The transfer case was tapered pipe plugs on the 14 and up. Just a little Teflon paste or even Teflon tape should be sufficient. Doesn’t need to be stupid tight either.

    Those crush washers do nothing to create a seel. They are just to help prevent over torquing of the bolts, once its crushed it doesn't provide anything more than just a typical flat washer. Even the washer in the engine oil drain is just a blue flat washer, replacing it doesn't provide any added benefit as long as you are torquing the bolt correctly.
