Why is the steering wheel heavy?

[Bradley]

The reasons for a heavy steering wheel are: 1. Insufficient tire pressure; 2. Different tire model replacement; 3. Damaged or poorly sealed dust cover; 4. Dirty, insufficient, or air-filled power steering fluid; 5. Torque sensor not calibrated; 6. Front wheel suspension deformation or abnormal wheel alignment; 7. Steering column stuck. The car steering wheel is a wheel-shaped device used to control the driving direction, which is connected to the steering shaft through splines, converting the force applied by the driver to the edge of the steering wheel into torque and transmitting it to the steering shaft. The method to adjust a heavy steering wheel to be lighter is: 1. Start the engine; 2. Turn the steering wheel to the left, hold it, then use a 17 wrench to drain oil and tighten; 3. Turn the steering wheel to the right, hold it, use a 17 wrench to drain oil and tighten, repeat this process three to four times.
