Please choose the correct ending to complete the given sentence: Sports and Fitness: [header] How to get the bearings out of skateboard wheels [title] Unscrew the nut that holds the wheel on the axle. [step] Use the socket on your skateboard tool to remove the nut on the end of the axle. If you don't have a skateboard tool, or it doesn't have a socket, use a crescent or socket wrench.

Ending1: The crescent and socket wrench is generally sold separately, and will be held in place by a plastic ring. The crescent and socket wrench secures the wheel in place on the axle but also frees it from the lug. Ending2: [substeps] Screw the nut or socket wrench onto the handle at one end of the wheel. Turn it clockwise until the wheel is loosened. Ending3: [title] Push down on the wheel with a small piston. [step] You may need to lean a bit to get it open. Ending4: Wheel nuts are usually ½ " (13 mm), so use that size. [substeps] Take the nuts off of all four wheels at once if you are changing all of the bearings.
