Product Assembly Insert another yellow cylinder and one wheel onto the open end of the axle. Please be sure the deeper hole in the wheel faces out, and the larger end of the yellow cylinder goes inside the body. Maneuver the cylinder until it locks into place. Cover with a fastener, with the spindle side up and aligned with the hole in the axle, then insert the spindle through the hole in the axle. Put a cover over the fastener, aligning the holes in the cover with the holes in the fastener. Insert two screws into the cover and tighten with a screwdriver. Repeat this process for the second wheel. 2. To attach the left and right handle bars to the dashboard activity panel, insert them into the holes on the sides. You will hear a loud 'click' sound. This indicates that the handle bars are securely fixed into the dashboard activity panel.
