front diff and t/c drain and fill

[3bears]

2000 4runner automatic..j-shift

so I went to change my front diff and transfer case fluids, only to find out that here at the shop we don't have the correct size allen to drain and fill the front diff. At that point I did not look at the transfercase.
One of my co-workers is running to town tonight or tomorrow ( depends on snow) Its a 3 hour round trip for us to get to a town of more than 15k people or any decent stores. I don't want him to get me a big set, just what I need.

Can someone tell me what size the allen is for the front diff, and what is on the transfer case. ? ( wrench or allen)

Its prob in one of Mtbtm videos, but on our limited bandwidth, we can not download or stream music or videos ( remote location)

10mm allen for the front diff, 24mm socket for the transfer.

I don't know the size, but any chance you would just be able to get something like this delivered to you?

I know living in the sticks presents challenges, but I didn't know how I would have built up my 4Runner without online shopping.

this time of year UPS does not come up here. the post office does not come here any time of year. SO usually I have my amazon stuff shipped to our office ( 3.5 hour round trip) and one of us runs to town one time a week to get supplies and hit the office for shipments.

Scoping-out the front diff now actually. Yes, a 10mm Allen alright.

The rear, which I have not done just yet, but a 15/16" socket feels quite good on there too. Just another option possibly, should one not have a 24mm available...

This and they are normally on their pretty tight so a braker bar is helpful.

And make sure that 10mm is fully seated or you'll round it out.

the front diff drain size is different from the fill hole so you need to get two allen sizes. sorry, but i forgot the size of the fill hole.

i'd recommend to get the ratchet-type for ease of loosening/tightening instead of the L-type allen wrench

I’m going through this right now. You need a 10mm and 12mm Allen for the drain and fill on the front diff.

I believe this is true for 96-98 but after that they were both 10mm.
Wouldn't hurt to have both size wrenches though.

Don't forget to loosen the fill plug first. Also, make sure to use new crush washers on all your drain bolts. they're super cheap.
