What Causes the Steering Wheel Noise in the 2021 Corolla?
2 Answers
Specific causes of steering wheel noise in the 2021 Corolla include a faulty clock spring, insufficient lubrication in the shock absorber top bearing, loose stabilizer bar bushings, and dirty power steering fluid. The clock spring is a wiring harness that rotates with the steering wheel. If it becomes entangled, it can cause noise when turning the wheel. Since this involves the airbag system, it must be inspected and adjusted by a professional. The shock absorber top bearing, also known as the thrust bearing, is commonly used in MacPherson strut suspensions. Its main functions are shock absorption and acting as a movable link for the vehicle body to prevent direct friction. If the bearing is damaged, it can cause noise and vibration when turning the wheel while stationary. Applying grease can solve this issue. If the noise is not from the shock absorber top bearing, check for loose or damaged stabilizer bar bushings. Loose or damaged bushings can cause noise not only when turning the wheel but also when driving on uneven roads. Adding shims can fix loose stabilizer bar bushings. Dirty power steering fluid increases pressure in the power steering system, leading to noise when turning the wheel. Regularly check the quality of the power steering fluid and replace it when necessary.
I've driven the 2021 Corolla a few times and noticed steering wheel noise, which might be due to worn steering column bearings. This component supports the rotating parts and is prone to friction noise over time or on rough roads. Another common cause is aging of the clock spring (spiral cable), a spring component inside the steering wheel that makes clicking sounds when turning. Lack of lubrication or dust ingress can make the noise more noticeable. Loose bolts at the base of the steering wheel can also cause noise, especially on bumpy roads where the sound becomes louder. It's recommended to visit a professional repair shop promptly for inspection and replacement to avoid major issues that could compromise safety. When driving, turn the wheel gently and perform regular maintenance and lubrication on these components to extend their lifespan and prevent potential hazards.
