What causes sudden abnormal noises in a car?

It may be due to damage to the front wheel steering knuckle. In most cases, the damage occurs in the CV joint of the half-shaft, leading to increased friction. When turning, the friction intensifies, resulting in noise. Below is relevant information: Steering System: A series of devices used to change or maintain the direction of a car's movement, whether forward or backward, are collectively referred to as the automotive steering system. The function of the automotive steering system is to control the direction of the car's movement according to the driver's intention. The steering system is crucial for the safety of the vehicle, hence all its components are considered safety-critical parts. Both the steering system and the braking system are essential systems that must be prioritized for automotive safety. Classification: Automotive steering systems are divided into two main categories: mechanical steering systems and power steering systems.
With over a decade of auto repair experience, the most common issue I hear about is sudden abnormal noises. Here's the thing - first you gotta pinpoint the sound source. If it's a creaking noise like a rusty door hinge, it's likely worn-out chassis bushings, especially noticeable over speed bumps. A metallic squealing from the engine bay? Probably a loose belt or failing water pump/generator bearings. If you hear clunking noises from the chassis while driving, pull over immediately to check for loose wheel nuts! The scariest is brake squeal - that's the wear indicator telling you it's time for new pads. Never ignore these sounds - catching them early means small repairs, but neglect could lead to transmission overhauls or even dangerous situations.
