Have a 2006 F250 4X4, 6.0 and having a very harsh vibration from the exhaust system. The dealer completed the TSB to replace the “Turbo Pedestal” and “Neutralize “ the exhaust.

The vibration is still there.

I know the service people and have no reason to believe the work wasn’t done. Vibration comes in between 600 and 900 rpm and then again between 1600 and 2000 rpm. Can really feel it through the floorboard and on the peddles, mirrors shake and is really bad on cold starts on cold mornings, not to mention the drone noise from the exhaust.

Any ideas welcome,,,
