Why is the steering wheel tight?
2 Answers
The reasons for a tight steering wheel are: 1. For hydraulic power steering, it could be due to dirty power steering fluid; 2. For electric power steering, it might be caused by a blown fuse, an open circuit, or a ground short; 3. Insufficient tire pressure; 4. Repeatedly turning the steering wheel while stationary or at low speeds. The steering wheel is a wheel-shaped device used to control the direction of cars, ships, airplanes, etc. Its function 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. The steering wheel mainly consists of a skeleton, foam, and corresponding mounting clips or screw holes for the driver's airbag (DAB). The gear system introduced between the driver and the wheels operates flexibly, effectively isolating severe vibrations from the road.
As an experienced driver with over a decade behind the wheel, the first thing that comes to mind when encountering stiff steering is whether the tire pressure is adequate. Insufficient pressure increases tire friction, naturally making steering more laborious. Additionally, the power steering system is crucial—for instance, an aging or leaking hydraulic power steering pump can make the steering wheel unbearably stiff. From my experience inspecting numerous vehicles, I've found that electric power steering motor failures are also a common culprit, especially in older cars where electrical issues may arise. Don't overlook the steering column and wheel axle components either; wear and tear or lack of lubrication in these parts can directly increase steering resistance. Cold weather can also be a factor, as components may contract and tighten. My advice is to first check the tire pressure, and if that doesn't resolve the issue, head to a repair shop promptly. Don't push through the discomfort, as it could lead to accidents.
