Why is there abnormal noise from the left front wheel of the car?
2 Answers
Car left front wheel abnormal noise causes are as follows: Lack of lubricating oil: Too little grease separation inside the bearing, insufficient lubrication of bearing grooves and steel balls, resulting in different rotation sounds. Bearing inner ring separation too tight: When the bearing contacts the clutch diaphragm spring, the inner ring cannot rotate with the spring, causing friction between the bearing inner ring and the diaphragm spring. Impurities in the bearing: Impurities may enter the bearing raceway, and original defects (such as scratches, dents, etc.) may appear in relevant parts of the bearing such as inner and outer raceways and steel balls. Bearing deformation: The bearing sealing ring or dust cover may be dented or deformed; it cannot be ruled out that the precision of the bearing or related connecting parts may be deformed or changed. Before installing the bearing, rotate it by hand to see if its rotation is smooth and flexible.
There's an abnormal noise coming from my front left wheel, usually caused by bearing issues. It makes a humming sound while driving, especially more noticeable when turning. The bearing is too worn out and lacks lubrication, leading to noise when it's damaged. Check if there are any loose bolts on the hub, as loose suspension components like shock absorbers or control arms can also cause noise. Last time my car made such noise on the highway, it almost caused an accident. Stop the car and gently shake the wheel to listen for any rattling sound to gauge the severity of the problem. Regular maintenance is recommended. Bearings tend to wear out around 100,000 kilometers, often causing such issues. If the noise is sharp, it might be a stone stuck in the brake pads. Don't wait for it to worsen; get it fixed at a professional shop immediately. Safety comes first. Delaying repairs could even lead to the tire falling off.
