My rear passenger tire makes a screeching/clunking sound moving forward only. Sounds at times like my tire has blown and is flapping on the pavement. I had the rear wheel bearing on that side done when I replaced the rear brakes this past November. I was told that my front "table bushings" would need doing but could wait till my spring tire change. Today I checked to see if the bolts were secure enough and noticed that I am able to push my wheel in and out quite easily. Is this dangerous and a potentially costly repair?
