Porsche 987 suspension noise

[jayfad]

Hi guys just registered, great site and clearly a great resource for owners.

I am looking for some advice.

I have a 2008 Boxster, owned for 2 years with 34k. Since I bought the car it has had a rattling noise, which seems to have worsened

The noise is like a loose rattle coming from the front of the car, both sides. The noise actually sounds like something loose, not an overly loud thump, but a definite rattle, almost like some loose trim (which it isnt). The noise only happens over small bumps, cobbles etc when traveling straight ahead, or turning left and right, ie all the time. Over larger bumps, small pot holes (not that I drive down them) the car is silent and there is not a sound and drives absolutely fine with no ride problems. It is almost like the less load on the car the noisier they are.

The car has had new drop links and anti-roll bar bushs fitted, a garage has checked out the car and say they cannot see a thing wrong with it and it passed it's MOT. There is no trim parts loose and everything is secure and tight but yet the noise persists.

Does anyone have any ideas as to what it might be. I read somewhere that strut top bearings can go. what kind of noise do they make.

thanks
