1. Worn or damaged wheel bearings: Wheel bearings allow the wheels to rotate smoothly and support the vehicle's weight. If they are worn or damaged, they may produce a knocking or grinding noise when the wheels turn.
2. Loose lug nuts or bolts: If the lug nuts or bolts that secure the wheels to the vehicle are loose, it can cause a knocking noise as the wheel moves around.
3. Damaged or worn suspension components: Suspension components, such as ball joints, control arms, and tie rods, help keep the wheels aligned and in place. When they become worn or damaged, they can create knocking noises when the wheels move over bumps or uneven surfaces.
4. Brake problems: Issues with brake components, such as worn brake pads or uneven brake wear, can also cause knocking noises when the brakes are applied.
5. Damaged CV joints: CV (constant velocity) joints transmit power from the transmission to the wheels and allow them to turn at different angles. If they are damaged, it can cause a clicking or knocking sound when the wheels turn.
6. Incorrect tire size: Using tires that are too large or too small for the vehicle's specifications can cause knocking noises when the tires rub against the fenders or other components.
7. Loose hubcaps or wheel covers: If the hubcaps or wheel covers are not securely attached, they can create knocking sounds when the vehicle is in motion.
If you hear knocking noises from the front wheels, it's important to have your vehicle inspected by a qualified mechanic or technician as soon as possible to identify and address the underlying issue before it becomes more severe or causes further damage.
