Diff Query

[323GTX-RSA]

Just a quick question, how different are the FWD front diffs and the 4WD ones? And would you be able to fit a 3.85:1 FWD diff into a 4WD gearbox?

I've never had an AWD trans apart but I've heard they are quite different and will not interchange

Thanks, I was just wondering if the 4WD diff was just a 2WD drive diff with the center diff bolted onto the side of it. They look very similar in the manual, and it looks that way.

I've not had a fwd trans apart, so i dunno either...

Jay - if you've had an awd trans apart, if I posted a pic of a fwd diff could you tell a difference?

let me clarify, I was thinking the about just using the ring gear from the 3.85:1 diff and bolting all the AWD bits to it, I assume that they can be stripped down to just the ring gear and that way I can keep what I need and just change the ratio. I won't have to worry about spline count and all that.

I have rebuilt and had both apart... They wont interchange...

This is a GTX diff apart... The ring gear on the far right by my cutting tool is all one piece and non removable.. It has teeth both on the inside of it and outside since the planetary for the awd part rides on the inside of the ring gear...



This is a few different G series diffs including a B6T diff..

..and now I don't have to go dig through my pix to try and answer the question, cuz sure's hell i don't remember!
