imho it's the camber plate, either the top nut is loose or the spherical bearing has worn out. Try tightening the nut with an impact driver first. If that doesn't work than swap the camber plates and see if the noise changes sides. During the swap you should also be able to inspect for any play and save yourself the time of taking it apart again. There's a outside chance it's the sway link but that usually doesn't make noise based on the driving in the video. BC will sell you a replacement bearing no problem,those parts wear over time and eventually need replacing.
