And be prepares to hear rattles and whines that have nothing to do with your problem. That’s called “rack rattle” and is built in just to increase your enjoyment of drivetrain diagnostics. ?‍?
Put it on a rack or jack-stands and run it to see if you can still hear the noise. Some times noises go away when the components aren’t under load, so this might not help. If you still hear it, see if you can localize it with a stethoscope or a hose held between your ear and each component.
Thanks! I figured the front would be stopped, didn’t even think about the cart hitting handle first. I might think about the dv8 rails, half the price.
