1. Before installation, the hub surface must be cleaned to ensure that the surface is free of dust, dirt, oil stains and other impurities.
2. Find the correct position and align the hub decorative cover with the hub center.
3. Fit the top of the decorative cover with the center of the hub, and then slowly tighten it clockwise. Usually, the decorative cover has a bayonet, which can make a "click" to indicate that it has been installed.
