Question on Rear Differential Drain Plug Washer

I just drained my rear differential fluid. Fluid was very clean after 100k+ miles.
But I am a bit confused and looking for advice regarding the washer in replacing the plug.

As the foto shows, it looks to me like the compressed washer.
And as there was no other washer with the plug when I removed it, my conclusion is that the washer is now bonded to the plug itself.
My attempts to pry it free have been fruitless.
What to do?
Put a new washer over it or find a better way to pry it off?
What say those with more experience than me?

 

I dont think thats a washer on the there....think thats the way its made...

most of use dont have that plug......thats a special aftermarket



you could heat it red hot and see if it separates........BUT that may destroy/damage that magnet,


Or spring for a brandnew $10 one.....like I had to


Should keep spares for all the crush washers on the truck...
......with Amazon/ebay its super easy to find em.

 

That appears to be an OEM 90341-18057 hex-head magnetic drain plug that has been over-torqued and/or reused to the point that the 90430-18008 washer has over-expanded & is now captured. I am a big believer in using magnetic drain plugs in the engine/tranny/front and rear diff. drain plugs of our 1st Gen Tacos. In 50+ years of wrenching, 27 years of which on the 1st Gen Taco, I have never removed a magnetic drain plug that did not have at least some magnetic goo (fuzz) stuck to it. Our 1st Gen Tacos had factory installed magnetic drain plugs in the front and rear diffs., but I also added OEM magnetic drain plugs to both the R150F tranny and R100 Tcase much like the Lexus vehicles.

Not my pic but excellent info:


I have also used the inexpensive $3 OEM 90341-18021 short Allen-head magnetic drain plugs in the R150F tranny and R100 Tcase on my '97 V6 Taco 4X4:

 

Here’s the set I bought for my truck. Covers most everything if not all

 

Okay. That ring is definitely part of the plug itself.
I was using a handmade aluminum funnel to catch the oil.
When I was cleaning up the washer was stuck to that.
That's why I missed it at first.
Thanks everyone for your insights.

 

In Sicyota04's post there appears to be enough washers for two changes. Is that true? However, there aren't any Engine drain washers. Where can I buy a complete set of fill and drain washers for

• Front differential
• Rear differential
• Transfer case
• Transmission
• Engine

on my 1998 Tacoma and how do I know which ones go where (or does it really make a difference)?

I prefer not to buy them from a Toyota dealer.

 

I've always just bought the kit Sicyota04 posted, and then bought engine oil pan washers separate (actually bought some rubber ones for the engine oil pan that spread out as you torque the drain plug down, and they've worked very nicely). Haven't found a complete kit that pairs engine oil washers with the rest.

I usually just try to match up a new washer of the same style as what was on that particular drain or fill plug prior, but honestly I've switched some up on accident and it's never mattered for me.

 

I bought my oil crush washers with the filters
