Sway bar end links need replacing. You cannot inspect them without removing them from the vehicle, and the mounting holes get gouged out, causing the clunk. My originals went bad in 35k. I would also replace the sway bar mount brackets and rubber bushings, and get the newer 06 and up brackets and bushings with the groove in the center.
