When replacing a wheel, look for a metal sleeve in the center of the bearing that may be out of line. Forcing a screw through a sleeve that is out of line could ruin the wheel.

Remove any obstructions inside the bearing of the new wheel, and move the inner sleeve in the bearing with an Allen key so that the screws can slide into the bearing freely.

Put the replacement wheel into place in the scooter frame.

For extra security, you can add a small amount of threadlocker glue to the the bolt and tighten it just until until it doesn't fall off or lock the wheel.
