If it has picked up a "death wobble" shake in the front end and steering wheel, check all the rod ends and the steering box bolts, and the unit bearings in the wheel hubs. If a tire hop, swap front to rear and if it moves then the tire is either out of balance or like was said a belt let go. My death wobble is a steering box getting loose (only about a 1/16 turn on the bolts)
