My 2012 sorrento has developed a driveline vibration. I had it to my local alignment shop and the only thing the could find wrong is the carrier bearing is worn. One of the parts stores that I deal with says it’s a dealer item. Now when I called the dealer the show a repair kit( I’m assuming a new bearing) but he questioned me and said he has never sold one. Has anyone ever replaced theirs and is it any more difficult than replacing any other carrier bearing?
