Most likely a bearing. But if the bearing allowed the shaft to drop. Impeller, and maybe gears. Won't know for sure until it's apart. The impeller to disfuser clearance is tight. You're talking thousands. When i worked on PAP units. We would set them up with about .020 clearance. On this smaller stuff, I don't know how tight they run it.
