What Causes the Steering Wheel to Suddenly Become Stiff?

[EstherLynn]

The reasons for the steering wheel suddenly becoming stiff are: 1. For hydraulic power steering, it may be due to dirty power steering fluid affecting engine power and performance; 2. For electric power steering, it could be a blown fuse or a broken circuit; 3. Repeatedly turning the steering wheel while stationary or at low speed, which puts a heavy load on the power steering system; 4. Insufficient tire pressure. The steering wheel is generally connected to the steering shaft via splines, and 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 intermediate shaft serves as a connecting component between the steering gear and the steering shaft, facilitating the standardization of the steering gear, compensating for errors during manufacturing and installation, and making the installation of the steering gear and steering wheel more reasonable in the vehicle.
