Where did you get them for when you did your diff oil change?

 

I reused the old ones. None of them are leaking...

 

Dealership. Should be a next day part if they don't already have some in stock. Be prepared to break a $1 though...

 

did you just ask for crush washers?

 

I just use parts store fibre washers on all of mine.

 

Here are the parts numbers for mine. I would assume they are the same size. They should be able to get them for you anyway by referening their computer, but it may help if you have the parts numbers in case you get a hardheaded parts guy:

Regular (non-crush) type fill and drain plug gasket for transfer case, rear differential, and transmission: 90430-18008

crush type for the same stuff above: 12157-10010

The gaskets on the front differential will be different. They were on mine. There are two size gaskets. I only have one part number and it is:
90430-24003 I can't remember if it is for the drain or fill. It seems the drain took a 10mm hex and the fill took a 12mm hex to unscrew. Newer models may have just 10mm for both??

Toyota apparently uses the same ones over because none of the dealerships here ever have more than two in stock. But, they can order them for you. You just have to wait a day or so to get them.

 

perfect thanks Nic!
