Anyone else has the annoying ticking sound from the wheels on the 09 CTS-V when turning? I went to the dealer and according to the GM TSB, it's the Brembo Brake dust gathered between the rims and wheel hub. The fix was clean it, torque the lugs to 150 ft-lb.(wow) and that's it.........but the noise is back and more frequent than ever, and now it does it when accelerating or braking too. Any ideas?
