Hi. I am hearing an odd chain dragging like sound when I tow. Nothing is loose that I can find, and I don't feel any drag when going down the road. My wife has listened as we move, and thinks it so...
The last time I looked at something like that I found brake parts laying inside the drum. It could also be the actual little "hub cap" that covers the the end of the hub and the bearings, may have come loose and is just rolling around inside the decorative cap for the wheel. Check it before towing again.
