How To Replace Skateboard Bearings

Using your skate tool or a socket wrench, tighten each nut down slowly. This will push the bearings down into the wheels. Make sure you take your time and don't crank too hard or fast on the nuts, or you can damage your bearings. Tighten each nut down until it feels snug, and then STOP. Don't crank on the nuts too hard - you want the nuts to fit on snuggly, and to be done turning. That's it.
