What Causes Steering Wheel Stiffness When Turning?
2 Answers
The reasons for steering wheel stiffness when turning are: the power steering fluid is too dirty or there is air in the lines. The function of the steering wheel is: to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft to achieve the purpose of changing the vehicle's direction. Steering wheels are categorized into: single-spoke, double-spoke, three-spoke, and four-spoke steering wheels. The method to adjust the height of the steering wheel is: 1. Locate the lever at the bottom of the steering wheel; 2. Press down the lever to adjust. The reasons for unusual noises when turning the steering wheel are: 1. Friction between plastic components; 2. Lack of power steering fluid; 3. Aging of the steering tie rod ball joint; 4. Noise from the stabilizer bar; 5. Steering gear malfunction and aging of the power belt tension.
I once encountered a steering wheel sticking issue while driving on the highway. Later at the repair shop, I found out it was due to a problem with the power steering pump—insufficient oil pressure caused intermittent power assistance, making the steering wheel extremely hard to turn, as if something was jamming it. This kind of issue needs immediate attention, especially during high-speed turns where a sudden steering lag can easily cause the car to veer off course. I recommend first checking if the power steering fluid is low or leaking, then listening for any unusual noises from the pump. If you hear a grinding sound when turning, that pretty much confirms it. For cars with electronic power steering, you’d also need to check sensor data, but that’s hard to handle yourself—best to leave it to professionals. Having the mechanic routinely inspect the steering system during maintenance can save a lot of trouble, since the steering wheel is literally a matter of life and death.
