Thanks for all the suggestions. I have noticed that when depressing the brakes the clunk is much more pronounced. It seems to happen when I press the brakes on even payment as well. I have also noticed a click sound with each rotation of the back left wheel. Hopefully this is brake related as well as the sound is rather metallic. The brakes have been squeaking while not being depressed. Next saturday the pads are being replaced and the rotors are being turned. I have a sneaking suspicion that the ball joints might be the culprit for the clunk. Am I looking at a big job????

The dude.
