987.2 - small stones / debris sliding around in the rear?
Discussion
I recently picked up a 987.2 Cayman and have noticed that under hard acceleration, braking and cornering, I can hear what sounds like small stones / gravel sliding around on metal somewhere in the rear. At a guess, there's some road debris that's made its way into somewhere and is rattling around. It's not a major problem, but it's a little bit annoying.
Is this a common issue? What would be the best approach to getting this cleaned out - are there easy ways to taking bits off so that I can have a look, or would I be better off getting it to someone who knows what they're doing?

Are you sure it's not rattling from the tailgate or trim in the rear? I had a 987.2 Cayman that under hard acceleration and high revs would make a sort of rattling tappet noise, but turned out it was the rear trim (I removed the trim and it was gone). I removed the plastic undertrays (you can do it with a socket set, they're just plastic nuts) and there were quite a few stones in there, likewise flicked in from the rear wheel arches (also easy to remove if you remove the rear wheel and there are torx screws and more plastic nuts). However with an engine between you and there it's unlikely you'd hear them (which was the conclusion I eventually came to). Removing the soundproofing above and in front of the engine shows how loud the thing actually is.
Every Cayman I've been in has rattled and I spent a while on that one and now the 987.2 S I've got removing trim parts and putting felt tape all over them. Still got one at low speeds and uneven surfaces sounding like it's coming from behind the passenger seat on the front of the engine which my last one also did - no idea what it is so I've learned to live with it!

I don't think it's rattling - I have a separate series of rattles that happens on bumpy roads that I've just accepted as being normal. 
This definitely sounds like loose stuff is rolling around on a hard plastic or metal surface, I can hear it rolling forward on braking and then getting flung to the back on acceleration. Stones sitting on the undertray sounds likely - do I have to get it onto a ramp to remove it, or can it just be done on the ground?

I've a gravel driveway at my place & have suffered terribly with stones flicking off the tyres into the brake calipers. The way they're designed is such that a small stone can get irretrievably wedged between the pad & the disc & the only way to get them out has been to take the wheel off & dig them out with a tool.
You can't miss it, the car sounds like the bearing's are blowing up every time you go round a corner. If you get that, it'll be a racing cert a stone is wedged in.
I've found stones & for that matter, any fixings you drop onto the undertray can be cleared by tapping the undertray until they work their way out to the side or at least in reach of your oily fingers.

I'll try and give it a good thud when I get home to see if I can get anything to move.You can't miss it, the car sounds like the bearing's are blowing up every time you go round a corner. If you get that, it'll be a racing cert a stone is wedged in.

Have you checked the storage bins below the 3/4 windows?
I did - these are empty. It doesn't sound like a noise from inside the cabin, but could be wrong.....Gassing Station | Boxster/Cayman | Top of Page | What's New | My Stuff
