Removed two thin nuts and a washer. This is what the sealed bearing looks like. The axle is a quick release, although you can't tell from the picture. The words on the rubber part of the bearing says, I think, G200RS, which shows up as a sealed bearing when I search for it on the google and also use the key word bearing. If the side to side play gets worse, will it just damage the bearing or will it damage the axle too?
