What's with all the clunking? Any thoughts, ideas as to solving this problem? I noticed that the stock sway bars have this sort of welded on stopper in between the brackets, where as hotchkis didn't have that on there bars. Could this be the problem, and if so how do I fix it.

Make sure everything is tight in the front. I have seen and talked to a lot of customers and we have done it also. You miss one or two bolts and the thing makes noise. This is where I would start.
