What Causes a Rattling Sound When Turning the Steering Wheel While Stationary?
2 Answers
When you hear an abnormal sound while turning the steering wheel while stationary, it is likely due to the friction between the spring steel piece of the horn wire transmission and the steering wheel. Typically, the sound originates from inside the vehicle and resembles a metallic rustling noise. The solution is to apply some lubricating oil at the friction point between the spring steel piece and the steering wheel. Below are the reasons for abnormal steering wheel sounds: 1. Sound from the turn signal reset: If the turn signal is activated while turning, the sound may come from the rebound clip of the turn signal's automatic reset mechanism. This is a normal occurrence, but the driver should confirm it. 2. Abnormal sound from within the steering wheel: If the sound comes from inside the steering wheel, it is most likely caused by the clock spring (spiral cable) of the airbag. To address this, remove the steering wheel airbag clock spring, apply some grease, and check if the sound persists. If it does, replace the clock spring as it may be damaged. 3. Aging of the steering tie rod end: If the steering tie rod end is aged, it can cause the steering wheel to vibrate and produce noise. In such cases, the steering tie rod end should be replaced, followed by a four-wheel alignment.
As a mechanic who frequently deals with steering issues, I can explain the causes of the creaking noise during stationary steering. Insufficient or aged power steering fluid in the system is a common factor. When the fluid level is low, the pump can draw in air, creating bubbles that lead to the creaking sound. Additionally, worn ball joints in the steering linkage or dried-out rubber boots losing their lubrication can cause friction noises when the steering wheel is turned. Damaged gears inside the steering gear could also be the culprit. The creaking noise occurring only during stationary steering is often due to increased hydraulic system load without adequate lubrication. I recommend checking the power steering fluid level immediately and topping it up with fresh fluid if it's low. If the problem persists, be sure to visit a repair shop to inspect the ball joints and rubber boots. Early repairs can prevent more serious safety hazards, and don't forget regular fluid changes for maintenance.
