Man, Have you tightened those fricking endlinks up yet? Mine was doing the same damn thing and all it was was the left end link needed about a half turn tightening and no more noise. You've had 20 people tell you that. The new struts have slightly larger holes in them than the stock. So tighten them up, I bet the noise will be gone. Lock tight it while your there and mark the bolts as I said before. Just because the parts are new don't mean they cant be loose.
Here's why it makes so much noise - the sway bar actually works as a spring, at static position it has no load. The least little turn you make the bar gets loaded because of chassis roll, that is why it helps handling. Through bumps, etc. it also gets loaded, only then it is a sudden loading not a gradual loading as through curves. That is why if you go to a larger sway bar your ride will be diminished some because it increases the overall spring rate of the suspension. When a component on that bar is loose, even just slightly, each time the bar gets a sudden loading that bolt takes a jar, the vibration (noise) caused by this carries right through the chassis of the car. If left loose long enough the component attached by the bolt can cut through the bolt, as well as wollow out the hole in that component.
I hope this helps.
