Standard oil change was performed.
I had a clunking in the rear of the car, turned out to be the sway bar knocking up against the arms. You could see the protective coating on the sway bar wearing through. It was attached correctly still and the mounts all looked good. I can only assume it is more broken in then when I originally put it on. The sway bar is now on its tightest setting of the two and so far has stopped the knocking.
