by Mary Ellen Popolo

The power steering system of your 2002 Ford Explorer is responsible for providing ease and agility in steering. The power steering pump is one of the components of the steering system. Failure of the pump results in a loss of hydraulic power, which makes turning the steering wheel difficult. Other signs of problems with the power steering pump include a loud whining noise when you turn the steering wheel and leakage of power steering fluid. If your 2002 Ford Explorer is suddenly hard to steer, you may need to replace the power steering pump.
