The power steering pump is a vital component in most vehicles, designed to pressurize hydraulic fluid, which assists in turning the steering wheel with ease. If the steering pump fails, common symptoms include fluid leaks, unusual noises, and reduced steering assistance. A sudden loss of power steering is often caused by a broken drive belt or depleted steering fluid. While most vehicles use a hydraulic power-steering system, newer models may employ electric power steering to improve efficiency and reduce power consumption.
