Try this one first.
No special skills or tools required.
That sounds like a good idea. A Haynes manual is on it's way so I'm sure that will help and from the pictures I've seen online it should be fairly straight forward.
The oil does seem to be coming from between the casing and the hub but I suppose the brake cam o-ring on the inside could be the one that's let go.
