What Causes the Squeaking Noise When the Car Body is Slightly Twisted?
2 Answers
The causes of squeaking noises when turning the car are as follows: 1. Sound from the turn signal reset: If the turn signal is activated while turning, the noise may come from the rebound clip of the automatic reset mechanism of the turn signal, which is normal. Sometimes there are multiple sounds because the steering wheel has three automatic reset notches per full rotation—turning the wheel one full rotation will produce three clicks. 2. Friction between plastic parts: The steering wheel is usually made of plastic components. In colder temperatures, plastic hardens, which can naturally cause friction noises. 3. Noise from inside the steering wheel: If the noise originates from inside the steering wheel, it is likely due to the clock spring (spiral cable) of the airbag. Applying grease to the clock spring may help, but if the noise persists, the clock spring must be replaced as it is damaged. Caution: Carefully remove the steering wheel or disconnect the airbag fuse to prevent accidental deployment. 4. Aging of the tie rod end ball joint: If the tie rod end ball joint is worn out, it can cause steering wheel vibration and noise. In such cases, the tie rod end ball joint should be replaced, followed by a wheel alignment. 5. Steering gear failure: If the noise during turning is very loud, it may be due to excessive gear clearance in the steering gear, requiring replacement. 6. Noise from the strut mount bearing: Open the hood and listen for noise from the top of the strut mount. If the noise comes from the strut mount bearing, applying grease may help. If the noise persists, the bearing must be replaced. 7. Noise from the stabilizer bar: If the noise is not from the strut, check the stabilizer bar bushings for looseness or damage. Loose or damaged bushings can cause noise not only when turning but also when driving over uneven surfaces. Loose bushings can be fixed with shims, but damaged ones must be replaced.
My car creaks with the slightest body twist, which is mostly caused by structural issues like loose frame joints or screws rubbing against each other. From my experience, when older vehicles encounter turns or uneven roads, minor body flexing can loosen originally fixed parts, resulting in strange noises. This typically stems from several reasons: First, aging suspension bushings or loose underbody bolts create enlarged gaps due to wear; second, rusted and deformed door hinges or trunk latches; additionally, poorly secured interior panels or seat bases that squeak under pressure. If left unrepaired, it may accelerate wear or even compromise safety structures. The most practical solution I've found is to first tighten visible screws and replace rubber components. If the noise persists, a professional inspection for frame deformation or rust-proof coating application is necessary. Paying attention to these details during daily driving can prevent major repairs.
