OK... I just got a 09 Focus SE and the car only has 10K on it. I've now noticed front end has a banging noise. The car rides smooth down the road but every time I hit the slightest bump or pot hole.. the front end just bangs... its like someone put a huge marble in the engine bay and it keeps rolling from side to side. I think its the sway bar end links... I had them replaced don the my old 07 and it sounds similar. So if that's not it... then what else could it be after only 10K miles?
