Yes, it was the carrier
Yes, it was the carrier bearing. But then they either put something else together wrong or something else was vibrating. The dealer said the driveshaft was out of balance. It was fine before they worked on it. They took it apart again and put it back together and the vibration was better. But when I had the truck going over 80 mph it vibrated badly. So I traded it in for a new 2019 Tacoma. I need something reliable and could see that vibration problem going on for awhile trying to find a solution.
