What is power steering?

Your car’s power steering system helps you to steer the vehicle with ease. The power steering system uses a pump to apply hydraulic pressure to the power steering fluid. This helps the steering rack and pinion to move with ease, reducing the effort required to turn your vehicle. This whole system is powered by your car’s drive belt, which also often controls the water pump, alternator and air conditioning.

If any of these components fail, or your power steering fluid leaks, your car’s steering will become tighter, and require more effort. This can affect your car’s safety.

A worn, cracked or perished power steering belt will also fail a Warrant of Fitness (WOF).

Causes of faulty power steering:

power-steering-pump2Faulty power steering pump – The power steering pump is responsible for directing power steering fluid from the power steering pump reservoir to the steering gears. If it fails, power steering fluid will not be able to circulate the system. This will prevent power steering from working correctly. The power steering pump is also prone to developing leaks if damaged.

Symptoms of a faulty pump include:

  • Leaking power steering fluid.
  • Difficulty turning the steering wheel.
  • Whining noises and groaning noises when turning.
  • Visible damage and cracks on the power steering pump.
  • Leaking power steering pump hoses or connections
