What Causes Abnormal Noise from the Front Wheels of a Car?
1 Answers
There are five common issues that can cause abnormal noise from the front wheels of a car: a nail stuck in the tire, which creates friction noise with the road; worn-out brake pads that have reached their lifespan limit, causing noise when metal layers rub; leaking shock absorbers, which lose their damping effect; loose lower control arm ball joints; and loose chassis bushings or bolts. Below is a detailed explanation: 1. A nail stuck in the front tire: While driving, the metal nail may produce friction noise against the road. You should stop in a safe place, check the tire pressure of all four tires, and if sufficient, proceed to a nearby repair shop for a thorough inspection. 2. Worn-out brake pads: When the ceramic layer inside the brake pads wears away, the metal layer beneath is exposed, causing noise as it rubs against the brake disc. 3. Leaking shock absorbers: Shock absorbers contain hydraulic oil to reduce large vibrations when driving over bumpy roads, improving passenger comfort. If the oil seal is damaged, hydraulic oil may leak, leading to loss of damping effect and abnormal noise while driving. 4. Loose lower control arm ball joints: The ball joints are lubricated with grease, but if the dust cover protecting the grease is damaged, water and dirt can contaminate the grease, causing loss of lubrication and resulting in noise. 5. Loose chassis bushings or bolts: The chassis components are connected with soft bushings to isolate vibrations and enhance driving comfort. If these bushings are damaged or fall off, abnormal noise may occur. Similarly, loose bolts can cause misalignment between chassis components, leading to small displacements during driving.
