Makes a squeeking/grinding noise when?? When you're sitting still just turning the wheels back and forth or going down the road. Tie rod ends are notorious for drying up and making noise on Fords cause Ford didn't put grease fittings in most of them from the factory. If it's when turning your wheel back and forth could be tie-rods or dry ball joints. Otherwise could be in brakes like chuck said.
