A few months ago my Cayman was rattle/knock free but now it does it quite a lot, it’s definitely from the rear and occurs when either the front right or rear right wheels pass over rough tarmac (i.e. slight changes in road surface but not present over big bumps).

I would describe it as a light knocking sound which can happen very quickly and in succession, it possibly sounds like plastic but I’d only be guessing.

A-none extensive list of things I've tried includes:
  • removed the boot privacy cover
  • removed the tail light covers
  • lengthened/shortened the tailgate bump stops (though I mind maximum extension is better even if it means it takes two attempts to close the hatch)
  • checked the foam padding around in the brake light
  • checked the plastic cover on the tailgate is tight
  • checked the roof lining
  • checked all the rear plastic trim is tight
  • checked for loose components in the engine bay
Finally I stuffed some foam above the strut mount cover and the roof lining and wahey, one fewer rattle. Unfortunately the most annoying one is still present, and it’s got me thinking that this could be a suspension issue?

Picture for comedy value.



So my question is, does the gen 2 still suffer from the same stty suspension life as the gen 1? If so is this something I can identify by removing the wheel and inspecting the bushes?

I know these are sports cars and some resonance/creaking is expected from the stiff chassis and big wheels but this is beyond that, like I said it used to be silent so maybe as the mileage has crept up to 28k its become all too much for Porsche engineering.

Car is going to OPC soon, if they can't/won't fix it I shall go to TECH9 or Nine Meister as both are local.

Any way I look forward to fitting my 18" wheels soon, as that should make the car a bit friendlier in the 'real world'. Cheers

I believe I've jinxed myself as the left hand side is now starting to make gentle thuds when going over small imperfections in the road. To be honest I can live with it as I love the car but really its shoddy on a car as expensive as these are.

Having done a lot of googling it appears many people do just have to live with it, as some have replaced loads of components to no avail or for it to come back 3 months later.

Funnily enough I dont notice them with the music on but when I've got a passenger its embarassing.

Dolf you are absolutely right.

Thanks for input, glad its not just me. I love the car, but yes it is stiff and it is a compromise and yes everything else is boring!

No it still happens with a passenger and just as noisy in the wet.

A (slightly) scientific test I can use to demonstrate the issue is drive over a cats eye with the left hand wheels - silence! Do the same with the right and its clunk clunk!

Snooker balls, that does sound similar.

Can you expand on the fork arm? A picture would help, cheers.

Cheers

I'm happy to say I now have a Cayman with an almost silent interior, or at least I did until the temperature started to drop this week.

My tailgate which has previously been silent makes a terrible rattling noise now the rubber bumpers have got a bit cold. They were at their maximum extension so I've wound them in a bit, it's not really fixed it though.

Not sure what to do.
