NP231J issue (I think)

So I put in a Terraflex SYE this spring, about 500 miles on it, I drive it to work today and the rear axle is soaked, dripping ATF (I have an AX-5, so it's gear oil, only thing with ATF is the transfer case), nut aside from a little dribble at the rear yolk, the TC is dry, the driveshaft is dry, the control arms are dry, the u-joint at the rear axle is dry, the rear axle is positively drenched with ATF, its dripping from every bolt and every low point, its all over the fuel tank, all over everything from about the pinion back.

Any ideas? I'm guessing it has to be the rear seal in the TC, but it's just so bizzare that it looks like this -
