Why does a car make a whining noise?

[GeorgeAnn]

There are two main reasons why a car might make a whining noise: 1. Issues with the wheel bearings; 2. Problems with the tires. The primary symptoms of damaged wheel bearings include: 1. Abnormal noises while driving, where the main sign of bearing damage is a buzzing or whining sound during vehicle operation; 2. Body vibration, where if the bearing damage is severe enough to increase its clearance, it can cause the vehicle body to shake at high speeds; 3. Unstable driving, where excessive damage to the front wheel bearings can lead to unstable movement and erratic power delivery during high-speed driving. Bearings are crucial for supporting the vehicle's weight and enabling tire rotation, enduring pressures and vibrations during driving, as well as exposure to rain, sand, and gravel.
