This truck has a vibration at highway speeds. Also, it shutters on takeoff. The dealer replaced one bad Hankook tire but that made little difference. Anyone having the same issue ?

 

Mine sometimes produces a vibration that is due to shifting confusion... On a flat road it'll upshift and hold the gear even though the rpm's are dropping pretty low...kind of like a standard shift telling you it time to downshift. A good press on the accelerator generally convinces it to downshift and eliminates that shuddering. I'm not impressed with how the transmission picks gears..it's really quirky. My old F250 Super never did this kind of stuff.
