Deere 455 rear axle leak

[theedudenator]

I have hydro oil leaking from the axle housing.
I am assuming this is coming from the seal for the axle?

Is this a hard one to fix?
I am ok with removing the axle for repair, but don't want to open up the hydro.

Is it the actually a leak from the end of the axle. Because the seal for the differential lock pedal usually pushes out on those tractor and they leak oil fairly fast
