Brake/Wheel on 2005 Chevrolet Uplander

My right rear wheel is making a scraping noise. I jacked the car up and rotated the tire and it makes a consistent scraping noise at certain point in the wheel rotation. Are there rotors on the rear of this vehicle and could it be warped? Confused

You'll need to remove the wheel and inspect the brakes to see what is rubbing. It could be the wheel rubbing on something, or the brake or e-brake as well. It may even be a low brake pad warning sensor.
If you have warped rotors the brakes will vibrate, so that isn't the problem.
Get it looked at by a shop if you don't have the tools and ability to perform this.
it could also be your wheel covers
