Is the steering wheel shaking? Maybe a tire out of balance. The expeditions are notorious about noise from the drivetrain. lol Mine whines from the rear. You didn't give much info in your post. Year and drivetrain (motor trans 4wheel or 2wheel drive) would be nice. A bit more of a description of the problem would be great too.

We’re the tires balanced to try and stop the shake, or did the balance start the shake?

We’re the tires rotated when they were balanced.

Does change in throttle position have any effect on the shake?

Does change in steering angle have any effect on the shake?
