Adjustable strut rods making terrible sound 74 Swinger

Pretty simple to isolate. Did it make the noise BEFORE you made the strut rod swap? If not, then it's either the strut rods, or something they are causing, like putting the lower control arm(s) in a bind. I agree with Kent. The movement of the lower control arm perfectly matches the frequency of the sound. Only trouble is, the shock is also attached to the lower control arm. I would drop the front shocks off it and drive it to eliminate them.
