I just got back from a quick Elk hunting trip and noticed that my front differential was leaking @ the left seal. It is not leaking bad enough where I can't drive it, but I am going to take it in tommorrow. I have a question. Do I need to worry about being denied warrenty service with a leveling kit on? I really don't think that that would have anything to do with it, but you never know with dealerships. Also, is this a common thing with the front differentials?
