Consumer Description

MY 2012 SIENNA AWD XLE HAS 103K MILES AND HAS A WHIRRING NOISE COMING FROM THE REAR DIFFERENTIAL AREA FOR A WHILE NOW. THE PITCH AND VOLUME IS PROPORTIONAL TO SPEED AND IS LOUDER AS SPEED INCREASES. MY RESEARCH TELLS ME THIS IS A COMMON DEFECT WITH THE COUPLING BEARINGS IN FRONT OF THE REAR DIFFERENTIAL. IT SEEMS THAT RAV4 OWNERS GOT A RECALL FOR THE SAME ISSUE, BUT SIENNA OWNERS DID NOT. TOYOTA HAS REDESIGNED THIS PART ON LATER MODELS TO AVOID THE ISSUE. HOPE YOU CAN GET THIS RESOLVED. THANKS.
