have a look at the front suspension bushes, these are like rubber gromets snadwiched between washers and the swaybar front susp arm.
you can find these where the swauybar connects to the front suspension arm. when i had the clunking noise, it was those, and the rubber grommet.. well it wasnt there!
about 5 dollars for each gromet i would suggest as i got em free from work, 2x9/16 spanners to undo. make sure u lift up car.
after this, no noises at all, but hey its a good place to start looking as there easy to overlook.
