4x4 .2003 f150 supercab.the old girl is driving me batty.when i turn the steering to the right im getting what sounds like a grinding noise.i cant pinpoint it but it sounds like out of the front end.one hub was changed about 10,000 kms ago but for the life of me i cant remember which one.jacked up off the ground nothing seems loose .turn tires no noise ,grab and twist no movement .any suggestions or thoughts.i hate it when i cant find anything and its driving me to distraction.would a hub just starting to go act like that?the hub that was replaced just went last winter and i actually thought i had a rock in the front brake rotor.bad grinding right away but this is not quite the same or im just going nuts.
