Not sure what the kingpin is? The Kingpin is the large bolt that runs through the center of your skateboard trucks (the red line in the photo shows the location of the kingpin inside your trucks). You are going to want a skate tool that fits on the nut on the end of your kingpin. Some trucks use a different style, and you need to look and see what kind of tool you will need. Most skateboard trucks are similar, but some need different tools, for example Grindking trucks. Grind King trucks use a hex hex wrench, and Grindking makes their own skate tool for working on their trucks. However, Grindking kingpins still work the same way, so these instructions will still work for you.
By far, most skateboard trucks work the same way, and have a regular bolt for their kingpin, and you can use the same skate tool on all of them. Throughout these instructions I'm using a Project skate too.
So now you have your trucks ready, you have your tool ready, and you know where the kingpin is. Great, let's get to ripping these trucks appart...
