Are the differential crush washers the same?
 

For the fill and drain plug? I cannot find the fill crush washer online without having to pay $15 for the shipping but I found the drain crush washer for about $6 for two shipped my house. Anybody have any idea? I did search but could not find it online and I figured someone on here has to know...

i dont think the differential washers are Crush washers ... (don't Need to replace)

Thanks for your time but I did enough research to know that both transmission washers are just aluminum washers and that both the differential washers are crush. I also went to the website that you posted already but I do not want to pay the $15 shipping like I said. I already have all the part numbers as well. I just want to know if the differential fill and drain crush washers are the same. I know that somebody on the forum already measure them with a digital caliper and found them to be the same size but he did not mention if they were interchangeable. I was thinking that maybe they just have different part numbers or something...

There are two different crush washers for the differential, but they can be used interchangeably.

We include both crush washers with our trans/diff maintenance packages, and all three crush washers in our full fluid change packages.

Two different part numbers, each can be used for drain and/or fill.

And yes, they are crush washers. You can reuse them being very careful and in you are in an emergency, but for the price, they should always be replaced.

I love reusing crush washers just to live dangerously.

anyone have the subaru part numbers for those diff washers?

Differential fill plug gasket: SU00300122 - 24mm OD x 18mm ID x 2mm Crush
Differential drain plug gasket: 1215710010 - 24mm OD x 18mm IDx 2mm Crush

I ordered two of the 1215710010 on ebay for about $2 each plus shipping and am gonna use it for both the fill and drain.

Are the trans plug washers interchangeable with the diff's?

No those are aluminum washers and not the same size.

I was looking at the fluid change package, curious as to why you need motul 300 LS. I thought it would be okay to use Motul gear 300- 75w90 for both transmission and diff?

It is. The LS is actually a bit thicker even though the weight is still in the 75W90 category. For those that have aftermarket clutch type diffs, the LS also has the proper additive package.

Both will work in the stock torsen!

So the washers are interchangeable for the diff drain + fill
And for the trans drain + fill?
So I only need 2 different types of washers?
Are the trans the same as the oil plug's?
And lastly, I know the diff drain plug is magnetic, is the stock trans drain also magnetic?

I'm getting ready to change my fluids so I appreciate the info!

No. They all use different washers



Transmission drain and fill are the same. They are solid type washers. The drain plug isn't magnetic as far as I remember.



Diff drain and fill are different from each other. Both are crush type washers. That isn't to say you couldn't just buy one and use it for both, but the parts catalog calls for different parts.


Obviously only one oil washer. Crush type
