I have been sorting through my new Mercedes and think I found a source of a noise. It has a clicking noise in the rear. I put a wrench on the sway bar link and could move it up and down and got about a 1/4-1/2 of play with a click on movement both ways.

I assume that I have to pull the wheel to gain access. I saw the link at pelican parts for less than 10 dollars. Might not be hard to make a strut arm using a piece of metal and get it done right now.
