What is the typical consequence of a failing power steering pump on vehicle handling?

The typical consequence of a failing power steering pump on vehicle handling is increased steering effort, particularly at low speeds or during parking maneuvers. A power steering pump is a hydraulic pump that provides assistance to the steering system, reducing the amount of force required by the driver to turn the steering wheel. When the power steering pump begins to fail, it may not generate enough hydraulic pressure to provide adequate assistance. This results in the driver having to exert more effort to turn the steering wheel, especially at low speeds where the steering system requires the most assistance. In severe cases, a completely failed power steering pump can result in a complete loss of power steering assist, making the vehicle very difficult to steer. Other symptoms of a failing power steering pump can include noise from the pump, such as whining or groaning sounds, and erratic steering assist. Reduced power steering assistance can make the vehicle more difficult to control, especially in emergency situations, and can increase driver fatigue.
