I have a 2012 Limited AWD that has the dreaded humming noise coming from the rear differential. Based on my research on here, I'm guessing the beaing has failed in my viscous coupler. It seems many have replaced the failed bearing due to the high price of replacing the coupler assembly. However, I did find one post that stated the replaced bearing started making noises again after a year or two. What is the latest consensus with dealing with this issue? Are people replacing the bearing or replacing the entire assembly?
