2010 chevrolet HHR clunking from front suspension,rough road,slow speeds

is this typical of worn sway bar bushings or somthing more expensive?

If this is happening with a low mileage 2010 vehicle I am going for design error or vehicle abuse. Did you not expect someone to say/ask/think “why is this not covered under warranty”? Have you checked TSB’s on this vehicle, it is too new for me to check?
