... Generally the droplinks go first then one or more of the control arms.
The ball joints wear and make clunking noises.
You'll have to get under the car with the suspension unloaded to test the components.
Happy Boxstering,

... is making clunking noises as he goes over bumps, it's in really bad shape.
But, it could happen. As jg says after 40K mikles they need to be replaced.
Front engine mounts that are done will generally start making noise as you put lateral force on the engine.

Pelican lists it as a front part, but I recall this being the identical piece at all four corners. My experience, after changing just about everything else out, was that this caused the noise. Oddly enough, although not air temperature dependent, the noise, a low amplitude rattle on sharp bumps, only occurred after the suspension was exercised for a while. Fortunately, I didn't change out the other, more complex arms which are a lot more expensive.
I don't have my invoices handy so as to tell you the exact Porsche part number, but you can ascertain this for yourself.

Alan, I will be very curious what you discover, as I have nearly identical sounding issue on my '01 Boxster S. (standard suspension) This is my 2nd vehicle and only 30K miles unbelievably. My sound is near right rear from best listening....everything feels tight (from driving perspective...have not had it unloaded), but as you said a "clunking" sound similar to a loose bolt or clamp. How many miles do you have? Let us know what you find....

Not a metallic clunk at all.
A couple years apart the noise occurred at the front and rear suspensions. The eventual cure each time was the control arm that I mentioned previously. Again, it will make noise only after the car has been driven a bit; and only on small, sharp irregularities at that. You will not feel or see any play. Last time I had it changed the part was 185 bucks, and both left and rights were changed out because the noise was impossible to locate side to side, even with a microphone attached to the suspension. I had once brought the dealer parts guy some hard to find beer, and when I got the control arms the second time he didn't charge for one.
