Cub Cadet Front Axle Leak

[ewhitake]

Greetings folks. I have a Cub Cadet 7200 that sprung a leak while parked in the garage. Here is a photo. Looks like the leak comes from where the joint is (you can almost see what looks like red paint next to it. ) Anyone know what I would need to do to repair? After looking at the parts diagram, I can't tell if there is a ring of some sort right at that joint.

Thanks all!
