Topic: Need help identifying differential

[87Fontana]

I bought a 4Runner from a guy in Arizona a couple years ago and he gave me some parts. One of them was a Toyota 3rd member. I went on some websites that show the 3 and 4 ribs on the 4cyl and v6 housing. Those pictures don't quite match the one I have. It does have a part # stamped into it that appears to be 35140 and 26H. Does anyone know 100% for sure what this is?  See attached pictures.

From looking at the pictures, that appears to be an 8.4" differential found in non e-locker Tacomas, and T100/Tundras.

it looks like a t100 housing but with 4cyl gears. Its missing the cage on the carrier cap bolts

That’s a really obscure V6 DIff it is an 8 inch, I just bought one of those from the junkyard they come from like a 97 or 98 2Wd V6 forerunner.

Hello all. Been awhile since I've posted something. OK Some quick info on what I've got. '97 runner sr5 with a A03A 3rd member, running 31's. I want to put a Dura Grip in. My research has led me to believe that my 3rd is a 8.4" with 2 pinion. Other research tells me that the 8.4" and the 8" are the same. Is that true?
2nd I'm considering changing my gear ratio to 4.88's. If I do, is it necessary to upgrade the front ratio also.  Thanks for the advice in advance.

OP,
If you change the rear gearing, yes, you must have the same gear ratio for the front diff.

Good luck.
