well, if they're new and in replacing them you got rid of the noise and the noise you describe is the same now as it was then, two possibilities come to mind. One, a strut with premature failure. Two, a strut that is loose, either at the top in the strut tower or at the bottom on the hub carrier. Maybe a shot in the dark, but you might get the wheel bearing on that side checked. Could be on it's way out... Good Luck..
