Is It Normal to Hear a Squeaking Sound When Braking and Turning the Steering Wheel?
1 Answers
It is not normal to hear a squeaking sound when braking and turning the steering wheel. The causes of the abnormal noise are as follows: 1. The abnormal noise is not obvious at low speeds, but a uniform buzzing sound is heard at high speeds: This phenomenon occurs when a wheel bearing of the vehicle is damaged. Long-distance driving places high demands on the wheel bearings. Bearings of poor quality or those that have been used for a long time will fatigue and become damaged under prolonged high-speed operation, resulting in abnormal noise. 2. A rhythmic buzzing noise is heard at low speeds, and the noise weakens at high speeds: The vehicle's four-wheel alignment is inaccurate, and long-distance driving causes significant tire wear, leading to uneven tire wear and abnormal noise. 3. The idle speed is slightly higher or slightly unstable after high-speed driving: During prolonged high-speed operation of the engine, some of the carbon deposits inside the engine will burn off due to high temperatures and be expelled with the exhaust. This is why people often say that the vehicle feels lighter after high-speed driving. However, in some engine control systems, the engine control unit cannot immediately adapt to the reduction of carbon deposits in individual cylinders and continues to inject fuel and ignite according to the previous adaptation values, causing changes or instability in the idle speed. After the engine runs for a while, the control unit will gradually learn new adaptation values, and the idle speed will return to normal.
