How it works
A skateboard is a wooden deck with grip tape on top and a truck bolted under each end. Each truck carries an axle with a wheel at either end, and two bearings inside every wheel.

Parts of a skateboard truck
The baseplate bolts to the deck. A kingpin runs down from it through a washer, a bushing, the hanger, a second bushing and washer, and the kingpin nut. The hanger's arm rests in the pivot cup.
Nose or tail?
Both ends kick up, so look closer: the nose is usually a little longer and wider than the tail. The kicked-up ends are for tricks, for lifting the board up a curb and for popping it into your hand.
Trucks too loose or too stiff? Turn the kingpin nut: tighter squeezes the bushings for a steadier ride, looser turns more easily.
Questions and answers
What are the parts of a skateboard?
The deck with grip tape on top, two trucks and four wheels, with two bearings in each wheel. Mounting hardware bolts each truck to the deck, sometimes over a riser pad.
What are bushings on a skateboard?
Two urethane rings on the kingpin, one each side of the hanger. They cushion the hanger as you lean, and softer bushings let the truck turn more easily.
What is the wheelbase of a skateboard?
The distance between the two trucks, measured between their inner-most bolt holes. A shorter wheelbase turns tighter; a longer one feels steadier.
