Hub Caps and Wheel Nut Caps You will have to take hub caps or wheel nut caps to reach your wheel off nuts. If you have a standard hub cap, remove it by using the flat end of the extension. Pry along the edge of the cap until it comes off. Be careful, the rim edges may be sharp. Don't try to remove it with your bare hands. If the wheel has a plastic center cap, you do not have to remove the center cap to loosen the wheelnuts. Place the ratchet and socket end of the extention on the wheel nut withthe center cap on.
