I have been trying to keep tabs on this, because...well...
Anyway, a thought occurred to me. If I were trying to diagnose the source of this noise, one of the first things I'd do is put the car on a 2-post hoist with a person inside and see if the sound could be replicated when the car is not in motion. If the driver can spin the steering wheel L & R and the sound is happening...that would be extremely revealing, because:
1) it would 99.5% eliminate a loose item (such as a socket) rolling back & forth inside a framing member as a result of centrifugal force.
2) it would eliminate twisted and/or loaded suspension components, because the weight of the car is not sitting on the wheels/suspension and anti-sway bars.
3) it would -- or it should -- allow a man to get his ear nice & close to the origin of the sound in order to localize it.
4) (depending upon how the first three steps unfold) it would allow for a five-foot jack stand to be placed beneath one wheel (or one corner of the car) at a time...and then the car could be lowered slightly to load up that wheel (or corner) with weight and then repeat the experiment.
Perhaps some of this has been done, but I'm just sharing some ideas here.
