Dodge Dakota Driveline vibration

Woodchuck69

Vibration felt through the seat and gas pedal starts at about 35mph and continues at all speeds above 35. So far I’ve replaced front and rear u joints and balanced the tires but still have the vibration. Can you help me diagnose the problem?

First, rotate the tires. If the vibration moves to the steering wheel, then the problem is tires and/or wheels. If not, then it is in the drivetrain - perhaps the pinion angle.
