What Causes a Heavy Steering Wheel?

[DonovanMarie]

The reasons for a heavy steering wheel are: 1. Toe-in malfunction; 2. Steering gear or power steering pump failure; 3. Overly tight bearing fit; 4. Insufficient power steering fluid; 5. Contaminated power steering fluid; 6. Power booster malfunction; 7. Low tire pressure. The steering wheel is a wheel-shaped device used to control the direction of travel, connected to the steering shaft via splines, converting the force applied by the driver on the steering wheel's edge into torque transmitted to the steering shaft. Precautions for steering wheel operation include: 1. Quickly and accurately return the steering wheel to its original position when turning; 2. Avoid applying excessive force when turning the steering wheel; 3. Hold the steering wheel firmly with both hands when driving in hazardous mountainous areas or on poor road surfaces to prevent accidents; 4. Avoid turning the steering wheel when the vehicle is stationary.
