Hi everyone, my first post here, I got a 05 durango slt hemi, and whenever I drive over shutterbumps or large potholes, a large "thud" or clanking sound comes from the rear suspension area. Sometimes the sound is repeated over each washboard bump. I checked out the swaybar bushings and I think they are still good, does anyone have any advice, or a possible cause of this very annoying occurance?
