Cleaned the rotor hats and inner wheel hubs with break cleaner and clicking noise is gone. Suprised that no one else with a zl1 had experienced this. It was pretty loud and did it with turning the wheel even a little in either direction. Also suprised that the little bit of grease and grime that I removed even made a difference. Wonder how that causes it to make a clicking noise. Also installed the front rock guards and with only 800 miles had some noticeable chips on the inner lower fender well, this should def one of the first mods after a thorough paint correction and some ppf installed on key areas.
Many of us had this exact issue and it is a simple fix. Pull the wheels off, clean the surfaces on the hub and wheel, I put on a thin layer of grease to hopefully hold off corrosion, put wheel back on and torque it down. Problem solved and it never came back.
