Grinding/Rubbing from real wheel well??

[Caledelaney]

Recently picked up a 2002 Boxster S with 141000 miles. Runs like a champ. Randomly one day I started getting this rotational grinding or rubbing noise and isolated it to the rear passenger wheel well. Jacked up the tires, and you can hear it when I rotate the wheel, but I can’t seem to find out what it is.

It’s not from the engine, because the noise only comes when you’re actually moving and speed up and slow down corresponding to your speed.

I initially checked the E brake cable and wheel weights and dust shield and all of that seem to be fine. It’s not super noisy from the outside of the car (still noticeable), but inside when you’re driving it is quite noisy and annoying especially as you go faster because it just starts clicking away rapidly.
Also, check the tire to make sure it’s not anything in there.

When rotating the tire with the car jacked up, you can hear it and feel a slight resistance when it makes the sound, and then it releases, and then again and again and again, and again as you rotate the tire.

Thoughts or ideas on what it could be?
