Place the board on its side so two wheels are facing upward.
Replacing the wheels on your longboard can breathe new life into your skateboard. Over time, the wheels will wear down through the constant contact with the street, which can lead to uncontrolled slides when skating at faster speeds. Wheels come in a variety of sizes and types that will change the way your board rides. Larger wheels will provide a stabler and faster ride, while smaller wheels allow for more maneuverability.
Align the wide end of the skateboard tool over the screw that holds the first wheel in place. Turn the skateboard tool counter-clockwise to loosen the bolt on the end of the skateboard truck. Remove the tool and pull the bolt off the side of the truck. Complete this step for the wheel on the same side of the deck; then flip the board over and repeat for the remaining two wheels. Keep the bolts in a safe place as you will need them to secure your new wheels to the trucks.
Place the first wheel on its side. Insert the narrow end of the skateboard tool into the hole in the middle of the bearing inside the wheel. Twist the skateboard tool to pry the bearing out of the wheel. Turn the wheel over and repeat for the other bearing inside the wheel. Complete this process for each of the wheels until you have the eight bearings separated from the wheels.
Insert one of the bearings into the first new longboard wheel. Insert the narrow end of the tool and push down forcefully until the bearing slides into the bay in the center of the wheel. Flip the wheel over and repeat the process. Complete this process for each of the new longboard wheels until each wheel has two bearings.
Align the bearings on the first wheel onto the first truck and slide the wheel onto the truck. Replace the bolt on the end of the truck and use your fingers to turn the bolt clockwise until it securely rests on the truck. Align the wide end of the skateboard tool over the bolt and turn it clockwise until the bolt holds the skateboard in place. Do not tighten the bolt completely as it will restrict the wheel from spinning on the truck. Complete this process for each of the new longboard wheels.
