Gearbox/drive shaft clunk Options

[Euphoria]

Hey, I've had a fair few clunks that have come and gone since I've owned this car but I've had this clunk for a long while and it is getting extremely frustrating, everytime you lift off in a low gear, put your foot down or just make the car misfire the whole front end has a very loud clunk noise, almost like something under there isn't tight, like a loose engine mount, only everything is and I've literally checked every suspension/cross member and engine mount bolt.

both bearings have been done recently and are problem free, struts and springs were done a couple years back and all bushings seem to be fine.

I can see it possibly being the driveshafts as they have never been changed, only the boots have been changed but they are showing no signs of play or noise when the wheel is moved whilst jacked up, this is also making it not seem like gearbox.

I have noticed when the car is jacked up I can move the driver side spring and it makes a clunk type noise, where as the other side doesnt and either does any other car I've looked at.

How loud can a bad strut mount clunk? also is there any other ways to determine what is wrong?

Thanks.

Hello i m new to the 6gc i have the same problem and it seems to be the gearbox having the problem. I listen the clunk noise from the left side of the car and i also recently changed the cv but still had the clunk noise. Also my mechanic went under the car in the pit witch change the oil and i was going for 1/2 meter front and reverse and he said to me it sounds like is coming from the gearbox. Any idea what could that problem be? I don't know what else to think everything seems good and also i had recently align my car at an expert with computers and he checked also everything from bushing to all the suspension and he said to me that there is nothing wrong.

sorry for my bad English.
