Above and beyond what mastertech mentioned, have the shop check that the ball joints and tie rod ends, they are fairly common wear items on this vehicle, and make sure the wheel bearings are OK, they can also cause looseness in the front wheels.

Hello ,, it sounds like the tires are out of balance , or you may have a bent rim.. Any repair shop should be able to balance your tires and tel you if you have a bent rim when they balance them
