I serviced my 10 STS today, 40,000 miles on the car. Oil, filter, cleaned the K&n, and the cabin air filter. So I thought I'd just look around underneath. At the rear end, the differential has 2 big ol round pieces on the left and right side attached to the cv boots. Passenger side is totally clean. The drivers side has a dirty film of oil on the round piece. Nothing on the boot. no leakage on the ground. Just a light film of oil, on the drivers side. So I assume the seal is very slightly leaking. Would this be a concern? I still have warranty until May 2014. I hesitate taking the car in for something so minor, in fear something else will get screwed up along the way. I've yet to get one door, bumper ding in the 2.5 years ive had the car, and hesitate on leaving my car with anyone. thanks for any opinions!

I know the 05s and 06s had rear diff seal leaks that were common, but not sure about the later ones.
