Helll everyone new user here I apologize if I post this in the incorrect area. Picked up my first s2k just a couple days ago and today went under it for the first time. I have limited knowledge and experience with working on cars but I’m comfortable enough to do things myself. Anyways, I noticed fluid on the diff and grease all around the connection from the axle(?) to
the diff but only on the passenger side. As you can see in one of the pictures there is a gap on one of the connections but not on the other. I assume the fluid is leaking from there but don’t really know what my next step is, I cleaned up the grease and will continue to monitor if more is coming out or not. Any help or direction would be greatly appreciated!! The car drives perfect and shifts perfect and puts a smile on my face every time I go into the garage

 

Passenger side axle not in all the way. Need to pop it in so it looks like the drivers side. Top off diff fluid. Also change passenger side axle seal it still leaking after installed correctly. Make sure axle doesn't pop out again.
