Why Does the Car Make a Buzzing Sound When Turning the Steering Wheel?
2 Answers
The reasons why a car makes a buzzing sound when turning the steering wheel are: 1. The steering column lacks lubrication, causing high friction; 2. Insufficient power steering fluid; 3. Faulty universal joint; 4. Aging and hardening of the rubber bushings in the chassis suspension stabilizer bar links; 5. Damaged plane bearing. The steering wheel is generally connected to the steering shaft via splines, and its function is to convert the force applied by the driver on the edge of the steering wheel into torque, which is then transmitted to the steering shaft. Using a larger-diameter steering wheel reduces the hand force required from the driver when turning. The steering intermediate shaft, as a connecting component between the steering gear and the steering shaft, facilitates the standardization of the steering gear, compensates for errors during manufacturing and installation, and optimizes the installation of the steering gear and steering wheel in the vehicle.
When my car makes a humming noise while turning the steering wheel, I suspect there's an issue with the power steering system. This sound usually comes from a worn power steering pump or a loose belt, as low hydraulic fluid or aging components can cause friction noise. I've checked the fluid reservoir level—if it's below the Min line, adding fluid might quiet it down. However, it could also be that the steering gear itself is cracked or the motor is under too much load. Don't forget regular maintenance, such as a check-up every six months, which can prevent major repair costs. The humming isn't just annoying; it also affects handling safety and may increase risks during high-speed turns. So, don't delay—get it to a repair shop for diagnosis as soon as possible, since steering issues are a matter of life and death. The last time I had this fixed, it cost me 200 bucks.
