1. Wheel bearings: Worn or damaged wheel bearings can cause a grinding or rubbing noise. Check the wheel bearings for any play or looseness, and replace them if necessary.
2. Brake pads or rotors: Worn brake pads or warped brake rotors can also create a rubbing noise. Inspect the brake pads for any uneven wear or damage, and replace them if necessary. Check the brake rotors for any warping or damage, and replace them if necessary.
3. CV joints: Constant velocity (CV) joints are responsible for transferring power from the transmission to the wheels. Worn or damaged CV joints can produce a clicking or popping noise, but they can also sometimes make a rubbing noise. Check the CV joints for any leaks or damage, and replace them if necessary.
4. Driveline: The driveline, which consists of the driveshaft and universal joints, can also produce a rubbing noise if it is damaged or worn out. Check the driveshaft for any damage, and replace it if necessary. Inspect the universal joints for any play or looseness, and replace them if necessary.
5. Tire tread: In some cases, uneven tire wear can also create a rubbing noise. Check the tires for any uneven wear, and have them replaced or rotated as needed.
If you are not comfortable performing these checks or repairs yourself, I recommend taking your vehicle to a qualified mechanic. They will be able to diagnose and fix the issue accurately.
