The toyota magnets are not strong enough, you need neodymium magnetic plugs.

where do you buy "strong enough" magnets... this is all I was able to find via google: TOYOTA/LEXUS NISSAN/ INFINITI
what do you recommend?
what do you recommend?
Try 'magnetic drain plugs'...that worked for me earlier today. You need 1 24mm for the front diff drain, and 5 18mm's for everything else including the transfer case. I thought the pricing just a bit pricey. You can also search for 'rare earth magnets'...on my '01 LX, I just bought a few thin ones, maybe 2mm or so, with the o.d. to fit the end of the plugs. No issues after 7 years, with the diff and tc oil changed yearly.

They are not super strong, but the large size of the long magnet and vastly increased surface area does the job fairly well. My thoughts.... Everything required below can be purchased for $20... roughly the same as one decent neodymium plug. These can be, but are NOT frequently, a consumable part. Especially the rear diff drain. I'd like to see some research showing the neo magnets practical benefits here.. I'd consider them if they can be shown to be better.
Front diff fill plug 90341-18035
Front diff drain plug not applicable
Transfer fill plug 90341-18035 or 90341-18040 (see rear diff notes)
Transfer drain plug 90341-18021 or 90341-18057
Rear diff drain comes with a 90341-18040 which can be used for the transfer case fill. I like to use, as do many others, the 90341-18035 for the drain. The 10mm is much lower profile and less likely to get knocked out when should it contact something while offloading.
Crush washer seals 12157-10010
The 18021 and 18035 are the 10mm, and half the price of the 24mm pieces.

I use the neo on many of my other vehicles including the oil pans. They extract more metal than the stock magnets because they are much stronger. If you do some research on neo you will see they are better.
Brian-
Do you also recommend a 18035 plug for the rear diff fill plug or is it good to go as is?
Also, are crush washers used on all diff and t-case plugs? In other words, do I need six washer seals to complete a full service on both diffs and the t-case?
Thanks,
John

You use crush washers on both plugs on the rear diff, and the fill plug on the front diff.
You use flat washers on the transfer case...only reason that comes to mind is that the diffs are cast iron or steel, and the TC is aluminum. I would expect crush washers to fit and work on the TC, but they are NOT what the parts book shows.
You use a flat 24mm copper washer on the front diff drain.
I just ordered and received mine from toyota parts barn (google). Part numbers follow...
Crush washers...12157-10010 $1.02 each
Flat washers...90430-A0003 $1.19 each
Flat copper washer...90430-24003 $1.38 each
You can go online to TPB's website, select what you're working on, and see pics of everything. Stupid easy.

Steve, good catch. The front diff is aluminum, and the 10010 is shown for the seal on the fill... which is weird, as normally the aluminum pieces would have the copper or aluminum flat washer used as you've written. I assumed Toyota had gone to 10010 to keep things simple, and also installed them on the t-case. I've made a few novice mistakes in recent times, beginning to worry about it.
bjowett, my assumption (and you know what happens when we assume) was that the front diff was steel or iron...like I posted, I'm only guessing that's why the tc uses flat aluminum washers. No idea why the front diff uses crush washers on the fill plug and a flat washer on the drain...I doubt there would be an issue finding a 24mm crush washer. So, now I'm completely confused but I'm still using what the parts screen shows.
I would add, having wrenched professionally on Triumphs and Nortons and having rebuilt/restored a couple of Jags...I always anneal copper washers before use. They're supplied as quarter-hard so they can be punched with clean edges, but for sealing I like them dead soft. All that entails is holding the washer with a pair of needle nose pliers (use cheap-Chinese versions in this case) until they're cherry red, and drop immediately in a tin can full of water. When the sizzle stops, they're ready to go. British machinery tends to live on fiber and copper washers.
For even another solution to consider, check http://ph.parker.com/us/en/stat-o-seal
Stat-O-Seals have been used on all kinds of flying machines for many years...very good stuff and not expensive.

bjowett...I'm thinking if they kept things simple, thinking of my 100-series LX, they'd keep the same crushers on the rear diff, which they did; keep the same on the TC, which they did, and use aluminum flat washers on the front diff...not sure why they went to a 24mm drain on the front diff, and I'm surprised to see that the front diff is aluminum.
OT, I'm thinking of Tundra front brakes on my LC (2013) and your website shows them as out-of-stock. Please PM me when you get some time and let me know what I need to do the job. Thx
Yes, I run those. They are so strong you can't even line the plug up to thread it because of the magnetic force.
Just changed out Transfer Case and rear Diff fluids with Amsoil Severe Gear 75W-90
I ordered all the parts from Beno but Brian has them too
I used:
Transfer fill plug 90341-18035 (I accidentally used a 90341-18021 which is why I ended up with and extra 90341-18035, see pic below Don't think it's a big deal. Two magnets now are better than none.)
Transfer drain plug 90341-18021
--------------------------
Rear diff drain 90341-18035
Rear Diff fill 90341-18021 (check out how loaded the rear diff magnet it.)
--------------------------
Front diff fill plug 90341-18035
Front diff drain plug 90341-24016
Once I got to the shop I realized I did not have the Front diff drain plug 90341-24016 with me. We tried to break it loose to see if it would break easy and it WONT! I sprayed it with AERO KROIL and I'll try it again later now that I have all the parts in hand. Brain warned this drain bolt is sometimes and issue.
WONDERING will the extra 90341-18035 work as an oil plug?
I also got the chance to install Brian's Jowett's bjowett new Billet oil filter canister (it adds 48.5 hp)

Is this a typo? Does changing the cap on the oil filter really add 48.5 horsepower?
Is this a serious question?
