This car came with the 2 way quick release moton clubsport system. The rear canisters are exposed to the back seat of my 997.1 turbo because they used to be mounted on a roll bar that is no longer in the car.

Just bought the car from Original owner who had it since 2007. I am hearing a noise that seems to be coming from the passenger side canister. It sound like there are rocks in there and it's being shaken so it's like a rattle sound. Like there is no oil in there. I have not pulled the tire to see if there has been a leak of oil yet but I was just wondering if anyone knew what this could be?

The noise only happens when the car is in motion, not when stopped. Mostly when on acceleration or turning and not so much when braking.

Anyone?
