Front Diff seal leak

I've got a leak coming from the front diff on our 2001 325xiT. It is at the output flange on the passenger side, where the front passenger-side axle plugs in to the flange. It is definitely leaking diff fluid, as Redline 75w90 gear oil smells quite different than engine oil or CV joint grease.

Is there a seal here that I can replace? Like part #7 in the realoem diagram? Anyone done this while the diff is on the car?
