I too am starting to hear a bearing sound in the right rear at 47K. Question for all, prior to the bearing failing, has anyone else noticed a drivetrain vibration that preceded this? Ever since new, I had a driveline vibration, multiple tire rebalances, rotations etc. Dealer could never determine. It seems now that I am getting the wheel bearing whine the vibration has disappeared. Coincidence? Not sure, but I will mention to the dealer.
