You should lift the front end of your car and check by your self if you din't see any scratch or somenthing like that under the car, a mark that show if something had slip. Mechanics are suppose to lift your car by the little lip near the rocker panel, where you are suppose to put your jack if you change a wheel for a flat. Or they should, the mechanics, to lift your car directly under the floor where there is some kind of what looks like a beam. If you have an svt they might have some problems lifting it cuz of the height. But you should really check by yourself. If you accuse them, they will probably say that that part was already bend or broken, but if you're a good customer for them maybe they'll fix it.
Good luck
Nic.
