CLUNKING NOISE FROM BACK

[deetim2]

I have an 03 172.

the past 2 days i have noticed a noice when driving over bumps. after a the back end leaves a speed hump i get a loud knock coming form the back end. it actually sound like the parcel shelf but i have taken this and the spare out and it still does it. It soud like something heavy bumping in the boot area.

is it a shocker or my suspension or something. any advise please so i know what to expect from the Garge.

Check the shocks arent leaking, check the exhaust and mounts, make sure the heat shields have not come loose. Make sure there is enough clearence between the exhaust pipe and the trailing arm.
