The power steering pump in a Mitsubishi Lancer is a critical component that assists in steering by providing hydraulic pressure to the steering system. If the pump fails, drivers may experience difficulty in steering or hear whining noises when turning the wheel. Regular maintenance, including checking fluid levels and inspecting for leaks, can help prolong the life of the pump. If issues arise, it’s important to address them promptly to ensure safe and responsive handling of the vehicle.
