Rear Shaft leaking at 4x4 Transfer Case connection

I was looking underneath my 2016 Limited 4x4 Taco for something else when I happened to notice this leak coming from what appears to be where the rear shaft connects to the Transfer Case. Should I be concerned? Any fixes?

 

Probably wouldn’t matter what section you post in since a transfer case & drive shaft are on all 4x4’s
But being you have a 2016.

@Sicyota04 Rookie mistake, my bad.

 

Looks like grease sling from the driveshaft. I probably wouldn’t worry about it unless it got excessive.

 

Normal if you have Zerks and grease your U joints.

 

Grease from U joints. Mine looks the same because I don't wipe the excess well enough.
