Humming Noise in Cabin

I have an ML 320 (2002) with 60,000km. Bought used, Love the vehicle!!! I am curious if anyone else has heard a faint humming noise in the cabin while driving. It is not associated with braking. It seems to be there when moving, at all speeds, but not when stopped. Not related to turning either (wheel bearing common diagnostic). Maybe its normal.. Anyone wiht thoughts?:)

Could be the driveshaft center support bearing. usually 3-4 hours labor at a dealer.

Thanks for the quick reply.. Do you know if its covered under warranty? I got the extended warranty when i bought the vehicle last summer... will it get worse? or just keep the low humming pitch as it sounds now?

Thanks again..
