What Causes the Abnormal Noise When Turning Left?
3 Answers
Abnormal noise when turning left is caused by a faulty CV joint, and replacing the CV joint can resolve the issue. Below are specific details about the CV joint: CV Joint Introduction: The CV joint, also known as the "constant velocity joint," is a crucial component in a car's drivetrain system. Its function is to transmit the engine's power from the transmission to the drive wheels, enabling the car to move at high speeds. There are many types of constant velocity joints used in cars, with the most common being the ball-type CV joint and the tripod-type CV joint. CV Joint Composition: The CV joint mainly consists of a sliding sleeve, triaxial shaft, drive shaft, star-shaped sleeve, cage, and bell-shaped housing. Since constant velocity joints transmit heavy driving torque, endure significant loads, require high transmission precision, and are in high demand as safety components, their main parts are manufactured using precision forging processes.
When the left side of the car makes noise while turning, common causes include worn components in the suspension system such as shock absorbers, ball joints, or stabilizer bar bushings, which may produce creaking sounds under pressure during turns. Faulty steering components like tie rod ends can also squeak, especially under the increased stress of turning. Sticking or loose brake calipers may rub against the wheel hub during turns, generating noise. Another possible cause is worn CV joints, which can produce clicking sounds due to uneven force distribution when turning left. Tire-related issues, such as debris stuck in the wheel well or misalignment, may also cause noise. Hearing unusual sounds while driving is not only annoying but can also compromise safety and lead to loss of control. I recommend having your car inspected by a professional repair shop as soon as possible and avoiding high-speed turns to prevent worsening the issue.
A left-turn squeaking noise is often a signal of mechanical failure. The primary suspect is the suspension system: if the shock absorber top mount bolts are loose or the control arm bushings are worn, a dull sound may occur during turns. In the steering system, severe wear on the tie rods can cause a typical rattling noise when turning. For the brakes, loose caliper bolts may result in sharp friction sounds. A worn outer CV joint on the driveshaft is a common culprit, especially under the heavy load of a left turn. Tire or wheel arch interference is another possible source, such as abnormal tread wear contacting the fender liner. Regularly check the tightness of suspension bolts during maintenance. If an issue arises, don't delay—have an assistant listen while you turn the wheel in a parking lot, then proceed to a repair shop. Safe driving means taking no risks.
