What Causes the Steering Wheel Noise in the 2021 Corolla?
1 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.
