Looks like you have a transfer box leak there, not uncommon on these and usually a very slow leak so don’t tend to be that urgent. (Mines had one for three years). The level is easy to check by removing the 8 mm hex plug in your picture, it should drip once removed when full.

Definitely the transfer case. Looks like a new copper washer might fix that. While you are at it, get two copper washers and 2L of fluid, and change it. Some brake clean after on the housing and it should be good to go. Dan. 🇨🇦 2013 L405 5.0 SCV8

Cheers for the advice I will get transfer case fluid done then address the leak next week.
