Diff and transfer case fluid change

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.

• GENUINE TOYOTA GASKET KIT
• $21 12157-10010 Toyota Oil Drain Plug Crushable Steel Gaskets Set of 10 OEM 12157-10010
  12157-10010 TAKES QTY 3 TWO FOR REAR DIFFERENTIAL AND 1 FOR FRONT DIFFERENTIAL
• 90430-24003 TAKES QTY 1 FOR FRONT DIFFERENTIAL
• 90430-A0003 TAKES QTY 2 TRANSFER CASE

 

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.
