Your original concern, in post #1, was the scuffing / scoring of the CV carrier closest to the diff housing on what looks to be the passenger side of the car. While torquing loose bolts is always a good thing to do, unless the various suspension components are loose enough to move around contacting the CV carrier, they are most likely not the source of the scuffing of your CV carrier.

If you want to know what is causing the CV carrier scuffing then you need to move the car's rear suspension mechanism, on that side, through the full range of it's motion until you find the item that is contacting the CV carrier. The bad boy should be eminently apparent.

Once you have found that item, then you will have answered the question you posed in your initial post — everything else while possibly interesting ultimately is, at best, just window dressing in the resolution of how your CV carrier became scuffed.
