I posted awhile back regarding a clunking noise coming from drivers side rear wheel anytime I hit a bump or pothole as well as a bit ofa squeek when driving on uneven pavement. I was advised to check shock upper & lower mounts & bushings which appear to be tight and fine. I have noticed however a small crack in the rear swaybar bushing (see photo) - could this possibly cause the squeeking or clunking sound? Could it be the wheel hub loose? -It seems tight enough. Thanks for any advice!! - Tim
