What Causes the Abnormal Noise When the Car Turns?

[OKira]

Abnormal noise when the car turns can be caused by the following reasons: 1. Friction between plastic parts: Since the steering wheel is usually made of plastic components, if the temperature drops, the plastic may harden, naturally leading to friction noise. 2. Noise from the steering wheel: If the noise comes from inside the steering wheel, it is most likely due to the clock spring (airbag coil). Remove the steering wheel clock spring, apply some grease, and check if the noise persists. If it does, replace the clock spring as it may be damaged. 3. Aging of the tie rod end ball joint: If the tie rod end ball joint ages, it can cause the car's steering wheel to shake and produce noise. In this case, the tie rod end ball joint should be replaced, followed by a wheel alignment. 4. Noise from the stabilizer bar: If the noise is not from the shock absorber, check if the stabilizer bar bushings are loose or damaged. Loose or damaged stabilizer bar bushings can cause noise not only when turning but also when driving on uneven roads. Loose bushings can be fixed by adding shims, but damaged ones must be replaced. 5. Noise from the shock absorber thrust bearing: Open the hood and listen if the noise comes from the top of the shock absorber mount. If it does, the noise is likely from the shock absorber thrust bearing. Applying grease to the thrust bearing may help, but if the noise continues, the bearing must be replaced. 6. 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. 7. Improper tension or aging of the power steering belt: For mechanical hydraulic power steering systems, if the belt is too loose, too tight, or aged, it can produce abnormal noise. Adjust the belt tension or replace the belt.

I just had my steering system repaired recently, and turning noises are quite common. The main cause is aging chassis components – especially when the steering ball joints wear out, you'll hear a clunking sound during turns. If the shock absorber top mounts crack, they can produce a creaking noise. When the outer CV joint of the driveshaft lacks lubrication or wears out, you'll hear rhythmic clicking sounds during low-speed turns. Vehicles frequently driven on rough roads often develop deformed lower control arm bushings, resulting in dull thuds when turning. Additionally, deformed brake rotor shields rubbing against the rotors can create metallic scraping sounds – you can roughly locate the issue by listening to the sound source. My advice: don't delay. Steering system failures are no joke. Take it to a reputable repair shop for a lift inspection, focusing on load-bearing components like CV joint boots and control arms.

It can be quite alarming to suddenly hear strange noises when turning, with chassis noises being the most common. When the CV joint is worn, it makes a clicking mechanical sound during turns, especially noticeable during sharp turns. If the tie rod is loose, you'll hear a clunking noise when turning, and you might feel a slight vibration in the steering wheel. A damaged shock absorber bearing often causes a squeaking sound during turns, which worsens in rainy weather. Bulging or deformed tires can also lead to a humming noise when turning. I recommend identifying the issue based on the sound characteristics: metallic noises might indicate a scraping skid plate, while clunking sounds often come from the tie rod end. Don't rush to the dealership—first check if there are stones stuck in the tires or if the wheel nuts are loose, as these are issues you can fix yourself.

Don't panic when encountering turning noises, it's mostly an issue with steering linkage components. Clicking sounds when turning the steering wheel to full lock often indicate excessive clearance in the steering rack. Humming noises during low-speed turns require checking if the power steering fluid level is sufficient, as older vehicles are prone to oil leaks. Squeaking noises usually come from worn stabilizer bar bushings. Another often overlooked issue is sticking brake calipers, which can cause squealing sounds when wheels bear lateral forces during turns. Last week, my car made a clicking noise when turning right - it turned out to be a cracked CV joint boot that had flung out grease. After parking, feel the wheel hub temperature; overheating on one side suggests potential brake caliper issues. Early detection of these faults can cut repair costs by half.

I've encountered turning noises twice, with different sounds indicating different issues. The first time, there was a thumping sound during low-speed sharp turns, which turned out to be cracked stabilizer bar bushings. Later, there was a screeching sound when turning while braking, caused by the brake pad wear indicator scraping the rotor. Now there's a slight ticking noise on the car, which the repair shop says is due to cracked lower control arm bushings - the sound of metal rubbing against rubber during turns. Loose chassis bolts can also cause noises, especially in cars with modified suspensions. Try turning the steering wheel while stationary - if it makes noise, it might be a steering column issue; if it only happens while driving, it's likely chassis components. Remember which road surfaces make the noise worse to help mechanics diagnose.

Old cars making strange noises when turning is very common; I've handled dozens of such cases. The most typical sound is the clicking noise like marbles bouncing when the CV joint is damaged—the sharper the turn, the louder the noise. If it's a dull metal grinding sound, you should check the shock absorber top mount bearing; if this part fails, the steering wheel may also slightly bounce. Worn-out driveshaft center bearings can produce a humming resonance sound during turns. Additionally, overinflated tires causing abnormal wear may result in rhythmic friction noises when turning. A simple test is recommended: make 90-degree turns at different speeds. If the noise varies with speed, it's likely an issue with rotating components. If the noise is speed-independent, it usually comes from suspension parts.
