I have a 2013 gen 1. I’ve noticed this over the last couple weeks. The fill plug for my rear diff looks like it’s leaking but I can’t tell. It is not wet to the touch but mostly sticky and black in color. The size of the oil spot hasn’t gotten any larger. By the way the oil spots on the ground aren’t from my truck. I’m probably just going to replace the fill plug but wanted someone’s opinion. Thanks in advance I’ll link a picture
