Suspension clunk

[bd581]

Top of the shock mounts on the back of a 6 has been known to come loose. also known to break.
other things besides what others have said it to look and see if the sway bar is hitting the body. this can happen on lowered cars as it adjusts the angle of the sway bar. its set at an angle for a reason. fixed with adjustable end links.

common place for problems on the 3s is the sway bar mounting rubbers. could also be a possibility here aswell

And dont rule out things because you "have given it a shake" you must be one damn strong person to be able to simulate the loads forced on a car when driving.
The shake test will only work when things are really really stuffed

I tried to shake the exhaust as much as I could but still, it couldn't replicate that sound. I live in south side Brisbane.

Dame too far for me to have a look lol.

Placing my bets on it being a loose object in the back. Spare tyre or car jack.

Thought it was the car jack so I took everything out. Still making the noise!

I gave my car a test drive last night and it definitely sounds like it's the sway bar making the noise. Right now. I'm hearing a slight tinging noise as well as that clunk noise. Will have a look at the sway bar again to see if it is hitting anything.

Was a hot day in brissie. Couldn't help myself haha and yeah, I was standing on the ledge of the boot.

Does it make the noise when the loading on the suspension shifts from one side to the other? When my swaybar came loose it wouldnt make any noise if it was loaded up and riding bumps but as soon as I shifted from left to right it would make an awful noise. If the noise is there regardless and still clunks while you're going around a corner with the swaybar loaded up then it will be something else. Probably a loose connecting arm or dead bushing somewhere.

A suspension specialist can chuck it on a shock dyno and they should diagnose it pretty quickly.
