5.7 Hemi 05 jeep WK water pump replacement (part1)

this is part one ....however I caught something 28 seconds into this video that sounded like it shook my tool box or hit the lower back of the car garage with a icy snowball, too clanky sounding though..kind of like you tripping over your metal tool box sound.. the kiddo is at a friend's house, and my wife wont go out when its this cold. I checked the video surveillance footage and seen nothing.
