Hey all, I just noticed that I've got a really bad scrape/rattle noise coming from the rear right side of my trailblazer. It seems to start right around 40km per hour and it kinda sounds like something is dragging. I checked visually, the underside of the truck but nothing obvious was happening. Maybe a heat shield? I just had from the cat back replaced a month or so ago. Thy other thing different is, I used 4 low today and was on some fire access roads. Maybe a rock somewhere jiggling? Any ideas?
