pop the outer tie rods out of the wheel and see if there is in/out play in the rod or if it seems to loose. A new one will pretty much stay where you put it. I don't know if you would see the play if you leave it connected to the wheel, but you might try just jacking the car up and grab the tire on the sides and see if there is play. Make sure where the play if any is. Inner, outer, or the rack itself.
