What Causes the Grinding Noise from the Wheels?
3 Answers
Reasons for the grinding noise from the wheels: 1. Low tire pressure; 2. Malfunction of the suspension control arm; 3. Noise from the CV joint. In such cases, it is recommended to inspect the CV joint, tires, and suspension control arm. Tires are a crucial component of a vehicle, directly impacting driving stability and safety. Tire pressure is extremely important—it should neither be too high nor too low. Excessive tire pressure reduces the contact area between the tire and the road, leading to decreased grip. Conversely, insufficient pressure can cause the tire to deform in a wave-like manner during high-speed driving, accelerating tire aging. Tires are made of rubber, which naturally degrades over time, necessitating regular replacement.
As someone who frequently drives to construction sites, never ignore a rumbling sound from the wheels. The most common cause is worn wheel hub bearings – the noise resembles distant drumbeats that accelerate with vehicle speed. Last time my car had this issue, the bearing balls were worn out, causing noticeable vibrations through the floorboard at speed. It could also indicate aged shock absorber top mounts, particularly noticeable over speed bumps. Worn CV joints may produce clicking noises during turns. I recommend promptly lifting the vehicle to rotate tires and locate abnormal sounds. Neglecting bad bearings can damage wheel hubs, potentially doubling repair costs.
As a mom who shuttles kids every day, I'm particularly sensitive to wheel noises. Last week while driving my child to school, I heard a rhythmic clicking from the right rear wheel. Upon checking, I found a small pebble stuck in the tread. But if there's continuous rumbling, it needs attention - I once mistook it for a pebble, only to discover it was the brake wear indicator scraping against the rotor. A mechanic taught me this trick: noises during straight-line driving often indicate bearing issues, while turning noises may suggest CV joint problems. My advice: don't tough it out like I did - get unusual sounds checked promptly, because safety should never be compromised.
