What Causes Steering Wheel Abnormal Noises?
3 Answers
Steering wheel abnormal noises during rotation can be caused by friction between plastic components or noises emanating from within the steering wheel. Below are detailed explanations regarding steering wheel abnormal noises during rotation: Friction between plastic components: Since steering wheels are typically made of plastic parts, these components may harden and produce friction sounds when temperatures drop. Noises emanating from within the steering wheel: If the abnormal sound comes from inside the steering wheel, it's most likely caused by the clock spring (spiral cable) of the airbag. Try removing the steering wheel airbag clock spring and applying some grease to see if the noise persists. If it continues, the clock spring needs replacement as it may already be damaged. Note: Handle steering wheel disassembly gently or remove the airbag fuse to prevent accidental airbag deployment.
When I hear abnormal noises from the steering wheel while driving, common causes include lack of lubrication in the steering column, which produces a squeaking sound—usually resolved by adding lubricating oil. If the ball joint or bearing is loose, it makes a knocking sound like someone at the door, which can be fixed by tightening or replacing the part. A malfunctioning power steering pump or electronic power steering system may also cause a buzzing or chirping noise, so check if the voltage is stable. External factors like tire friction against the road or suspension wear can sometimes produce sounds from the chassis that are mistaken for steering wheel issues, so carefully identify the source of the noise. If the noise occurs during low-speed turns, it's often due to aging small components and isn't a major concern. However, if there's abnormal noise at high speeds, be alert for serious issues like a deformed steering rack and seek immediate repair. During maintenance, remember to lubricate the steering system every 10,000 kilometers—don’t delay, as neglecting this can lead to costly, labor-intensive, and dangerous repairs later.
Steering wheel noises should never be taken lightly as they may indicate safety hazards. A friction sound often means the steering system lacks lubrication—an easy fix. However, if you hear clicking or knocking noises, it could signal loose ball joints or damaged steering shaft components, which may cause loss of control at high speeds—pull over immediately for inspection. Overheated power steering motors produce a humming sound; while short-distance driving to a repair shop might be acceptable, avoid long journeys. I always prioritize identifying whether the noise originates inside the cabin or underneath the vehicle, then observe if it occurs during turns or straight-line driving. Early diagnosis at a professional shop prevents minor issues from escalating into major accidents—safe driving is paramount.
