1. Brake pads: Worn-out brake pads can cause a scrubbing sound when they come into contact with the brake rotors. Check the thickness of your brake pads and replace them if they are below the recommended minimum thickness.
2. Brake rotors: Warped or damaged brake rotors can also cause a scrubbing sound. If your brake rotors are warped, they will need to be resurfaced or replaced.
3. Wheel bearings: Worn-out wheel bearings can cause a grinding or scrubbing sound when the vehicle is in motion. Check the wheel bearings for any signs of wear or damage and replace them if necessary.
4. Driveshaft: A damaged driveshaft can also cause a scrubbing sound. Check the driveshaft for any signs of wear or damage and replace it if necessary.
5. Suspension components: Worn-out or damaged suspension components, such as ball joints or tie rod ends, can also cause a scrubbing sound. Check the suspension components for any signs of wear or damage and replace them if necessary.
If you are not able to identify the source of the scrubbing sound yourself, it is best to take your vehicle to a qualified mechanic for diagnosis and repair.
