Re: advice needed for rear suspension clunking.
rear suspension clunks could be due to many things i'm affraid. I agree that it could bethe anti roll bar bushes at the rear. If you poke your head under neath you can usually see them. follow the anti rollbar along and you will see the rubbers, although just the side of them as they are in clamps. See if they have cracks in them or show signs of excessive wear. If not them then the bottom arms have bushes in them too as do the trailing arms. its very difficult to diagnose these without the swap and hope routine. If yu do go down this route then the rear anti roll bar bushes would be the cheapest thing first. I can get a set for around £25 GB where as Alfa will probably only supply the bar complete for much more money than this. Sorry i cant be of more use here.
