I did the same thing you did to try and find out the issue and cure it. At first I thought it was ball joints or lower control arm bushings but the shop couldnt pin point it either. At that time I needed to replace my upper strut bushings and bearings cuz they wear out fast when you drop ur car. As soon as I did that the sound went away. I think it was the bearing in the upper strut bushing that was crushed and making the sound.
Now, 9 months later, I'm getting the sound again but even worse. Its coming from the right side as well. If I was you I'd try and replace the strut bushings first as they are the cheapest and also the easiest to do. If that makes it stop then wala!! If not then I donno.
