Over sharp bumps there is this springy rattle/jiggle coming from the area indicated, I HAVE TO solve this as it's all I hear now when driving my 2000 Boxster and ruining what is otherwise a very enjoyable car. Any ideas what can be causing this and also how easy is it to dismantle the interior trim in front of this section to see what the devil is causing this rattle/jiggle? Appreciate any help thanks!
