There are no other seals inside. If you could loosen those nuts with an 8" handle just tightening them up may fix your leak. Google "full floating axle" and you will find all kinds of info and pictures.

I agree. I've had axles like these leak on two different rigs, but in both cases all that was required was to re-torque the nuts holding it to the hub. If that doesn't help, the gasket behind the plate needs to be replaced. Easy to do, and the gasket is a very thin paper gasket. If you jack that wheel up as high as possible, (1" to 2") you won't have to drain the differential. You'll get a few drips out when you loosen the axle, but not a gush. Gaskets are available at any truck repair place.
