A driveline vibration TSB has been expanded to include 2009-13 Toyota Tacoma pickups.
This TSB (T-SB-0249-12) supersedes a previous the T-SB-0131-08 and now includes 2009-13 Toyota Tacoma pickups. The issue is that “some vehicles may exhibit a vibration felt in the seat, floorboard, and/or steering wheel around 15 – 25 mph caused by a second order driveline vibration.”

4. Test drive again to see if vibration is gone. If it still exists, follow the next step.
