That is way closer than mine are. Do you have the ss sway bar end links too? That the bar from the sway bar up to the strut. With the stock ls ones on a lower car they push the sway bar down since they are longer. The clunking could be alot of things. Sway bar bushings, the end links could be loose. They are a pita to tighten. I cant listen to your sounds right now, but control arm bushings are another common clunk, and ball joints are always an option also.
There are alot of thing the clunk going straight could be. If everything is tightened correctly, and the end links are the shorter ss ones, I would start with Sway bar bushings, then control arms, then ball joints. But imho, if it wasnt clunking before, and everything is tight with the correct end links, then I would think a bad strut. But again. I havent heard the clip.
Is the grinding sound on the right side only? If it was a wheel bearing you would probably have a droning sound all the time while going down the highway. Since it is only when turning, i am going to go with the axle also. Clunking while turning and accellerating 98% of the time is an axle.
