I am new to this site but hoping for some direction. I have a '07 HHR that has a grinding, metal sound when I turn the wheels or go over a speed bump. This is typical on cold mornings (days) but not so noticable when the tempature is warm (70 degress or more) outside.
I have repleaced the struts and shocks and bushings on the sway bar.

Any ideas/direction would be greatly appreciated.
Thanks!

 

Sway bar Links, hubs. If you replaced just the shock part of the struts possibly the Strut Bearings/mounts.
