Road noise or?
 

Hey all,
I have a 2006 Cayenne S, seems to get a lot of road noise at freeway speed. Does not seem to be bearing noise of any kind, but I will double check the rear bearings. I don't notice any vibration, but I am wondering could the drowning noise be caused by the driveshaft support? Sounds like tire noise but I do not believe that is the case. Other than that car has 100,000 miles on it, and runs like a top. Any insight would be greatly appreciated.

Thanks,
jason

In addition to the above, I was checking my cordon shaft and noticed a uni-carman UPC sticker? Does this mean it has been serviced once before? there seems to be very little play in the shift at the support, certainly nothing like the videos I have seen thoughts.
