What causes a single clunking sound from the front wheels when starting to turn?
2 Answers
The main reasons for a single clunking sound from the front wheels when starting to turn include: 1. Faults in the steering gear, power steering, or chassis components; 2. Malfunctions in the outer CV joint, shock absorber, or power steering pump; 3. Insufficient or deteriorated power steering fluid; 4. Worn or rusted ball joints; 5. Corrosion of the control arm ball joint. The issues mentioned above can often be resolved by applying lubricant, but there are several types of abnormal noises that require attention: Loose steering tie rod ball joint: This can cause steering wheel vibration, a loose chassis, and premature tire wear, so the steering ball joint should be replaced promptly. Aging or damaged CV joint boot: The engine's power transmission primarily relies on the cooperation of the inner and outer CV joints. The inner CV joint connects to the transmission differential, while the outer CV joint connects to the wheel. Each CV joint is protected by an outer boot, which prevents contaminants from entering and damaging the joint and prevents leakage of CV joint grease. When the protective boot ages or gets damaged, it can lead to CV joint failure, further causing abnormal noises during steering.
When starting a turn, the front wheel suddenly makes a clunking sound. I've encountered this several times, and it's mostly due to a loose or worn ball joint in the suspension system. Older cars are prone to this issue because the wheels bear greater pressure during turns. If the ball joint isn't secured properly, it will rub and make a sound, like a snap. I suggest shaking the front wheel after parking to check for any loose sounds—you can make a preliminary judgment yourself. Don't underestimate it; ignoring it for too long might even affect the steering components, making driving unsafe. It's best to visit a reliable repair shop as soon as possible for an inspection. A minor fix now can save you from bigger expenses later. Regular maintenance is key—it saves you trouble and keeps your car running smoothly!
