Most cars these days are fitted with power steering, which essentially means that a pump assists with the steering to make it easier to turn the wheels, even when the car is stationary.  The steering rack is connected to the front wheels and it’s the rack that allows the car to turn corners. This sounds simple in practice, however it is a bit more complex and the power steering system needs to be checked regularly to ensure proper working condition.

The largest cause of failure in this system is a worn power steering pump which will not only operate ineffectively, but they can also contaminate the steering hydraulics with metal particles. These are the most likely cause of damage to components in the system such as damaged fluid seals, sticky valves and scored shafts and power bores.

Leaking hydraulic pipes that drive the steering pump can also be an issue and need checking and from time to time, or replacing, as part of your regular service.

Power steering problems can manifest themselves during turns. If you hear whining sounds when negotiating a turn, have a qualified technician inspect your power steering system.
