What Causes the Abnormal Noise When a Car Turns?
2 Answers
Abnormal noises when a vehicle turns may be caused by the turn signal reset mechanism, aging of the steering tie rod ball joint, steering gear failure, damaged stabilizer bar, or friction between plastic components. Specific causes and solutions: Turn signal reset: If the turn signal is activated while turning, the noise might come from the rebound latch of the automatic reset mechanism. This situation is generally not a cause for concern. Aging steering tie rod ball joint: If the steering tie rod ball joint is aging, it can cause steering wheel vibration and noise. The usual solution is to replace the steering tie rod ball joint and perform a wheel alignment afterward. Steering gear failure: If the noise during steering is very loud, it might be due to excessive gear clearance in the steering gear, which requires replacement of the steering gear. Damaged stabilizer bar: Loose or damaged stabilizer bar bushings can cause noise not only during steering but also when driving on uneven roads. Loose stabilizer bar bushings can often be fixed by adding shims. Friction between plastic components: Since steering wheels are typically made of plastic, colder temperatures can harden the plastic, potentially causing friction noises. Regular inspection of plastic components and timely replacement are necessary in such cases.
I've encountered this situation several times when the car makes strange noises while turning. The most likely culprits are loose or worn-out suspension components, such as the lower control arm ball joint or stabilizer bar links. Once these parts wear out, they tend to squeak when subjected to turning forces. Another common cause is issues with the tie rods – excessive clearance can also produce noises. Don't forget to check the shock absorber top mount; cracks in this part can cause abnormal sounds too. Some cars may produce a clunking sound from the chassis when steering, which could indicate worn gears inside the steering gearbox. These minor issues can affect driving safety if not addressed promptly. I recommend taking the car to a repair shop for a lift inspection – it won't take much time to identify the root cause.
