What Causes the Clicking Sound When Turning the Steering Wheel to Full Lock?
2 Answers
The abnormal sound when turning the steering wheel to full lock is actually related to the resistance of hydraulic oil and the working process of the hydraulic power steering system. Here are the possible reasons for the abnormal sound when turning the steering wheel to full lock: 1. Faulty Thrust Bearing or Top Mount: When turning the steering wheel, a "click-click-click" sound may occur, which is likely due to a faulty shock absorber top mount/thrust bearing and requires replacement. If the power steering belt is improperly tensioned or aged (for mechanical hydraulic power steering), it can cause abnormal sounds; in this case, the belt tension should be adjusted or the belt replaced. If the power steering fluid is too dirty, it increases the pressure in the power steering system, causing the power steering pump to emit a "humming" sound, and the power steering fluid should be replaced promptly. 2. Faulty Clock Spring in the Steering Wheel: Especially for those who have removed the steering wheel, it might be due to a broken clock spring or an unplugged clock spring connector, which can be fixed by replacement or reconnection. Additionally, an aged steering tie rod end with excessive play should be replaced, but a wheel alignment is required after replacement.
I've been driving for over a decade and encountered many steering issues. The most common clicking noise when turning the wheel to full lock is usually caused by worn steering ball joints or tie rods. In this situation, when the wheel reaches its maximum angle, loose components will produce abnormal sounds. If not addressed promptly, steering precision will deteriorate, potentially leading to control failure. For example, I ignored this issue with my old car for a while, only to discover later that the suspension also developed problems, costing me extra repair fees. My advice is don't delay—get to a proper repair shop immediately to check the ball joints and suspension system. Regular maintenance of steering fluid and tires can prevent such issues. Safe driving is paramount, so never underestimate these minor abnormal noises.
