washers - help

[Gecko123]

I am going to be replacing the front and rear differential fluids and also the transfer case. What I like to know in advance is what washers do I need. There appears to be 3 types: flat copper washer, flat non-shiny silver, and a shiny raised silver washer.


I found this on the internet for a Tacoma. Is this the same for the 4Runner. can someone verify?
2 Crush washers for rear drain and fill plug
Part No:12157-10010 x 2
- 2 Crush washers for front drain and fill (larger copper washer is for front fill)
Part No: 12157-10010 x 1 and 90430-24003 (copper) x 1
-2 crush washers for transfer case drain and fill plug
Part no: 90430-18008 x 2


Second question, what 3 different types?

Just did myself last month. Toyota updated part numbers. I'll scan in my invoice for you tomorrow. PM me if I forget.

When I changed the fluids, I forgot to purchase the washers so I just flipped the OEM washers over and re-used. So far no leaks.

Turns out I can't find the invoice actually. Below is what I bought from Toyota Dealership parts department - these are the OLD numbers but they were able to still look up these old ones and convert to new ones. I remember paying $20ish for them (I wanted to play it safe at 100k miles). Many people have just reused theirs though as gm350 states.

Front Diff Drain
9043024003 (x2)

Rear Diff Drain
1215710010 (x2)

Transfercase Drain
9043018008 (x2)

Oil pan drain
9043012031 (x1)

I don't know if it helps much...but ive never changed any of the washers on any of my toyotas, and no leaks so far.

Question:
Isn't the front diff drain and fill take different washers?
