Tightening down the strut top nut eliminated the knocking over every bump while driving, but the knock in the video is still there. I don’t think it’s the strut mount/bearing. It really seems to be coming from either the steering transfer gears or the rack. I saw some side to side movement in the linkage right where it comes past the firewall that looks promising, Here’s a video of the movement what do you think?
