What Causes the Steering Wheel to Make Abnormal Noises?
2 Answers
Abnormal noises from the steering wheel are likely caused by the friction between the spring steel plate of the horn wire transmission and the steering wheel. The sound usually comes from inside the vehicle and is a rustling metal friction noise. Airbag Introduction: Airbag Clock Spring Malfunction If the noise is found to originate from inside the steering wheel, the issue is mostly due to interference from the airbag clock spring inside the steering wheel. Remove the steering wheel airbag clock spring and apply some grease to see if the noise persists. If it does, replace the airbag clock spring, as it may be damaged. Shock Absorber: Lack of Lubrication in Shock Absorber Plane Bearing If abnormal noises are heard from outside the vehicle when turning the steering wheel, it might be due to a lack of lubrication in the shock absorber's plane bearing. Simply open the hood and listen to see if the sound is coming from the top mount of the shock absorber to determine if it's the plane bearing making the noise. If the shock absorber plane bearing lacks lubrication, apply some grease. Loose or Damaged Stabilizer Bar Bushing If the noise is not from the shock absorber's plane bearing, check if the stabilizer bar bushing is loose or damaged.
I've been driving for over 20 years, and steering wheel noises are very common. It's mostly some issue with the steering system. The plastic parts under the steering wheel can make squeaky noises when they age or get dry and rub, especially in older cars that have been driven for a long time. If the ball joints are worn, you'll hear a clicking sound when turning, like small stones stuck in the chassis. If the steering column bearing is failing, you'll hear a continuous humming sound at low-speed turns. Insufficient power steering fluid or leaking steering oil seals are also common causes—when this happens, the steering wheel becomes very stiff. The most annoying is when the clock spring (spiral cable) fails, making a cracking sound as you turn the wheel. I recommend checking and replacing the rubber bushings or lubricating components as soon as possible—don't wait until the steering fails, as that could lead to bigger trouble. Safety first, after all.
