What Causes Abnormal Noise When Turning the Vehicle?
2 Answers
There are seven possible reasons for abnormal noise during vehicle steering: 1. Plastic components: Friction between plastic parts. The steering wheel consists of various plastic components, and if the gaps are too small during rotation, abnormal noise may occur, especially in new cars. This usually resolves after a break-in period. If the noise persists, try reinstalling the steering wheel. 2. Steering column: Friction with floor mats. Sometimes, aftermarket floor mats may be too large and come into direct contact with the steering column, causing friction during rotation. Adjust or replace the floor mats. 3. Steering wheel: Faulty airbag clock spring. Those who have disassembled the steering wheel should pay extra attention, as it might be due to a broken airbag clock spring or a loose connector. Replace the airbag clock spring or secure the connector. 4. Tie rod end: Worn or loose ball joint. Replace the tie rod end ball joint, but remember to perform a wheel alignment afterward. 5. Steering gear dust cover: Oil leakage. Replace the dust cover or reapply grease. However, reapplying grease is only a temporary solution. 6. Steering gear: Abnormal noise when turning could indicate excessive gear clearance in the steering gear, requiring replacement. 7. Strut mount or thrust bearing failure: If abnormal noise occurs when turning, it is likely due to a faulty strut mount or thrust bearing, which needs replacement.
I noticed abnormal noises when turning the vehicle, which could indicate minor issues with the steering system. There are several common sources: First, if there's a problem with the power steering pump, such as oil leakage or low oil pressure, there will be a humming sound when turning the steering wheel. Second, wear in the ball joints of the steering linkage can cause a clicking noise during turns. Aging or damage to the top mounts of the shock absorbers is another reason, especially noticeable when turning on uneven roads. Additionally, insufficient lubrication of the steering shaft under the steering wheel can result in a creaking sound when turning. Another possibility is a faulty front wheel bearing, where the noise becomes more pronounced at higher speeds. I've dealt with this myself by first checking if the power steering fluid is sufficient and topping it up if needed; if the noise is accompanied by difficulty in steering, it's best to have a mechanic inspect the ball joints or bearings. Regular maintenance of the steering system is essential to prevent noise from affecting handling and safety.
