So I took my cobra on a good cruise up north over the weekend and I noticed when I get home the back bumper was covered in oil, so I peaked underneath and saw my pipes and diff were covered in gear oil. I cleaned everything off and I can't find anything wrong. Does the IRS diff have a vent hole on the top? Or is there any known issues with the diffs leaking oil out of the speed sensor? I'm just not sure what's going on
