2002 Toyota Highlander - scraping noises from front tire

I can hear an intermittent scraping/rubbing sound from what appears to be the front wheel as it rotates. I can’t see anything around the wheel or tire that could be causing that but I haven’t taken it off. Any clue? Thanks

Worn out brake pads. Worn out bearings causing wobble and rubs. Something stuck in the brake caliper or on the knuckle. I could go on but why? You are going to inspect it. Eyes on the car beats internet every time.
