I wouldntput balljoints as the #1 cause of the vibration when driving over bumps in the roads.
I woudl suspect a issue with the steering dampner if equipped.
If the front end is out of aligned it could ruin the tires, and cause it to vibrate as described.
I would also suspect bad tie rods, they coudl be bent and have no play!
Wheel bearins are good?
