Log story short, my rear diff is screwed up. I know it is the 4.444 diff that's in it. Would a 4.444 off of an STI work In it?

Just to be clear, the diff that I'm looking at buying is off a 96 STI, it is a 4.444 R160, but I also saw on a forum that they're gear ratio is slightly different and I don't know if that would interfere with anything

I don't think your rear axles will work. I'm not sure, But think I heard that.

I was talking to the guy about and he said only a completely different diff would have different axles and of it's a 4.44 r160 they'd be the same

Differentials often aren't listed probably because they never fail and there's zero demand. Anyone parting Subaru's knows that rear differentials take up space, time, and only have value at the scrap yard. But you can look up transmissions and if they have the vehicle still, you can ask about the rear differential.

You're positive it's the rear differential? They rarely fail and are usually mis-diagnosed or replaced only to find the issue wasn't resolved.

But of course anything can fail. Since a 1996 US STi never existed it's not a common reference point.
You can also swap ring and pinions depending how and why you're replacing it - then you're simply installing your gear ratio into the new diff.

It should work, I believe 96 GC had male rear axles. Beware the pinion flange, however. Some time around 96-97 they changed the flange to a larger bolt pattern. They swap, but replacing it requires some "specialist" tools.
