hello,i have on a s40 2006 big knocking noise in front suspension;is this a common problem & from witch part ?

 

First I've heard on the newer models. Can you trace the noise to a specific area like the strut tower or anti-sway bar? On my 2001 S40 I've had knocking from a broken ant-sway bar bushing and from a busted strut mount. Nothing from my 2005 S40 though.
