ideas welcome - diff drain plug

Sorry Chris! Didn't see it.
C'mon by sometime and you can grind things flat, and I will cut a sliver of thick-walled DOM and weld it right on for ya.

Cool. Thanks Bill!

Go figure - I stripped the drain plug on my Tacoma front diff yesterday - and it already has a 10mm allen head plug from the factory. So much for those being the "better alternative" to a 24 hex head bolt....

Couple things:

1. The 10mm allen head magnetic plug, part #: 90341-18021 fits fine in the Tacoma rear axle.
2. For you guys that have made the switch to 10mm allen, did you put one of these in the fill plug as well? It fits fine in my diff, but I wondered if there would be any reason not to put a magnetic plug up there?
3. Is there a non-magnetic option?

2. Yes
3. Yes

As part of my axle service and gear swap I went with the "new" allen head plugs...The drain plugs are magnetic while the fill ones were not. Not sure what, if any, value there would be in putting a magnetic one in the fill spot as well

Not sure of the part #s or if they are the same # for an 80 and Taco but I could look up the number on my receipts if you'd like. Now I have 4 spare old school plugs should anyone ever need one in an emergency.

I just welded my drain plugs in. Took off the copper washer, cranked the plug in and went to town. My protection rings were ground off long ago. The weld bead is a lot harder than the bolt or the ring. I haven't ground through it yet.

Welded the nut to the lowest stud and crank that out to drain (most) of the oil.

Thanks Jeff. I don't think the PN I have is for a Tacoma - in fact, the research I've done indicates it's a special order part so I don't know what axle it's supposed to go with. But since most Toyota axles seem to use the same thread size for the diffs, I guess it works.

I'll ask Jerry for the non-magnetic option and see if he can locate it, but if you stumble upon the PN feel free to post it up.

I run the magnet ones everywhere, top and bottom. Not that much other than a little black sludge ever collects on the top one.

Can't find my receipt but a quick search on MUD netted this:

Magnetic Drain Plug: 90341-18021
Fill Plug: 90341-18016
Crush Washer: 12157-10010 (or might be 90430-18023)

Anyone recall if the 80 series center diff/transfer case drain and fill bolts are the same as the front and rear axle? I didn't think about it at the time but I might as well change those out as well
