Locate the visor bracket. It is the metal piece that attaches the visor to the roof of the truck.
Look for the two screws that secure the visor bracket to the roof. They are usually located on the underside of the bracket.
Use a Phillips head screwdriver to tighten the screws. Be careful not to overtighten the screws, as this could damage the bracket.
Test the visor to make sure it is secure.
Here are some additional tips for tightening a loose sun visor:
Use a quality Phillips head screwdriver. A cheap screwdriver may not be able to provide enough torque to tighten the screws properly.
Be sure to tighten the screws evenly. Overtightening one screw too much could put undue stress on the bracket and cause it to break.
If the screws are stripped or rusted, you may need to replace them with new ones.
If the visor is still loose after tightening the screws, you may need to replace the visor bracket.
