My left front side wheel bearing is grinding.
The grinding noise is most likely your brake pads grinding the rotor surface. Look through the wheel at your brake assembly and take note of the brake pad thickness. If it is down to the metal it will grind the rotor surface. You would be able to see evidence of this on the rotor (deep scars). Wheel bearings make a loud roaring sound when failing rather than grinding. If you need assistance, YourMechanic may have a technician in your area that can help you figure out the exact problem and complete necessary repairs to your grinding noise issue.
