Thanks, that looks like my driveline. it is leaking, best I can tell at the bottom of where it connects to the axle, at the 6 o'clock area.
If it is leaking where the cast carrier housing connects to the axle housing.
It might be a simple tightening of the carrier nuts.
See
Lubrication Leaks, (b.) Manual does not show torque spec on carrier nuts. it just says tighten securely.
