What Causes the Squeaking Sound When Starting and Stopping a Car?
2 Answers
When the car makes a creaking sound during startup, it may be due to clutch failure, transmission failure, lower arm failure, or inner CV joint wear. It is best to have it inspected and repaired at a local 4S shop or professional repair shop. When diagnosing car noises, it is important to create good auscultation conditions and try to eliminate interference from other noises to avoid affecting the accuracy of the judgment. Tips for starting a car: 1. The key action for starting on a flat road: is the coordination between the clutch and the accelerator, that is, the clutch-accelerator coordination. After lifting the clutch pedal to the semi-engagement point, slowly press the accelerator pedal while continuing to lift the clutch pedal slowly. 2. The key to starting a car on an uphill: is to overcome the uphill resistance and prevent the car from rolling backward. In addition to the essentials and operations of starting on a flat road, pay attention to the close coordination between the parking brake lever, clutch pedal, and accelerator pedal operations.
I've been driving for over twenty years and have encountered a few instances of squeaking noises when starting from a stop. The most common causes are worn-out or rusty brake pads, especially after driving in the rain—rust can create noise when friction occurs. Once, after driving on a bumpy road, the noise became much louder. Upon inspection, it turned out that the suspension springs or shock absorbers had loosened, causing the wheels to wobble and produce unusual sounds. Additionally, small parts like tie rods or ball joints can age and creak when under load during startup, and delaying repairs can worsen the wear. My advice is not to wait until you're driving at night and risk an emergency—just head to the repair shop and have a mechanic check the suspension and brake components. Cleaning and lubricating can often solve many issues. During regular maintenance, it's a good idea to have these parts inspected to prevent unexpected problems.
