Disassembling 4EAT front diff

Im trying to take apart my blown front diff (dont ask why). I undid the two bolts next to the things that surround the axle stubs that are covered in little teeth/notches, and figured those things were basically big threaded plugs. So I break out the hammer and punch, and start spinning them. 5-6 broken teeth later, and they dont seem to have move in any direction except around in a circle.

How do you get them out so you can get the crown/orbit dealie out?

goddamn, looks like you broke a halfshaft there.

wth did you do to it? lol

anyway, that's just the output shaft, the differential - if it's anything like a manual (it should be) is located inside the case and is mounted to a huge reduction gear - it's a small device in comparison to the reduction gear itself.

anyway, to get to it you've got to drop the transmission and split the casing. although I dunno how you would go about it on an automatic.

I'd just throw the thing away.

That sounds so much like me it's scary.

"I already replaced the broken part, and now I'm disassembling it for the hell of it, or maybe just to see what makes it tick..."

Hell.... I tore apart my old o2 sensor just to see what was in it.

Turns out they do just unscrew

Takes a hell of a lot of hammering tho :twisted:

IIRC I got 20 bucks for my part way disasembled 4eat at the recyclers. biggest perk of taking it apart was that now I have a huge bin full of very high quality M6 bolts and several other sizes.
