What Causes the Abnormal Noise When the Steering Wheel is Turned to the End?
3 Answers
If there is abnormal noise when the car's steering wheel is turned to the end, it is likely due to damage to the shock absorber pressure bearing. Replacing it should resolve the issue. If the noise persists, inspect the car's chassis suspension and lower control arm. The noise is usually more noticeable under the steering wheel. Relevant information about the car steering wheel is as follows: Function: Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft. Correct Grip: If the steering wheel is viewed as a clock face, the correct hand position is to place the left hand between the 9 and 10 o'clock positions and the right hand between the 3 and 4 o'clock positions. In the event of a collision, this posture provides better support for the body.
I noticed a noise when turning the steering wheel to its limit, which could be caused by several common issues. One possibility is wear in the steering system components, such as excessive force on the steering gear or rack when turning the wheel to the limit, leading to damaged internal gears or bearings that cause a creaking sound. Another possibility is low or dirty power steering fluid pressure—when the fluid is insufficient, it may produce a humming noise, especially noticeable at full lock due to inadequate pressure. There could also be issues with the chassis, such as worn-out or cracked CV joints, universal joints, or ball joint boots, which may produce squeaking sounds during extreme turns. Having driven many cars, I find that the common cause is prolonged habits of turning the wheel to the limit, accelerating part wear. I recommend avoiding holding the wheel at full lock for too long when parking and slightly releasing it afterward. It's best to visit a repair shop to check fluid levels and components to ensure steering safety. This issue is quite common, especially in older cars or with frequent sharp-turning driving habits.
Abnormal noise when the steering wheel is turned to the limit is usually related to components under excessive stress. I believe the main cause is an issue with the power steering system, such as insufficient or degraded steering fluid, which can cause the pump to whine or squeal when operating at extreme angles. Additionally, wear in the steering rack's gears or universal joints can produce a metallic clunking sound when turning to the limit. Chassis components like cracked control arm bushings may also create friction noises when twisted during sharp turns. I've handled similar cases before—diagnosis should start with the basics: check if the fluid reservoir level is normal, and top up with fresh fluid if low. If the noise persists, it's likely mechanical damage; avoid DIY repairs and have a professional inspect the steering linkage system with proper tools. Regular maintenance of steering fluid and components can prevent such noises. If you hear any unusual sounds while driving, slow down immediately and assess the situation.
