Real quick question. Not being paranoid... LOLOL I was looking under the new 06 the other day and noticed a TINY ( Not really enough to make your fingers greasy) Spot right where the Drive Shaft meets the back og the G56. I degreased and a tiny bit back again after a few hundred miles. Could this be some sort of Factory Grease that is making it's way out after 2000 miles of driving/towing? Not real concerned and I wouldn't really take it to the dealer yet, just figured I would ask. Love thenew truck and how it pulls my big trailer! Mileage is very good as well!!
