A scraping sound when driving, whether straight or in a turn is most likely brake-related, not ball joints. Jack it up, remove the two front wheels and check the rotors for grooves. You'll most likely find the driver side rotor grooved on the inside. If you have a parts store local to you and someone that can take you there, pull the rotors, have them checked for minimum thickness and turned if within tolerance. Then replace or rebuild the calipers and replace the pads.
