There's one screw that removes the truck on the bottom, it's very easy to put it back on.

Is this the screw, John? If it is, should I unscrew it all the way so it comes out totally or just unscrew it a few turns to slightly unloosen it?? This is my first time doing something like so I fear if the screw comes all the way out that I won't be able to correctly  screw it back in place.
