Power steering makes parking and low-speed manoeuvring effortless. When it starts failing, you'll notice quickly — steering becomes heavy, noisy, or unpredictable. Here's how to recognise power steering problems early and what to do about them in Perth.
Hydraulic vs Electric Power Steering
Older vehicles (generally pre-2010) use hydraulic power steering (HPS), which relies on power steering fluid pressurised by a pump driven by the engine. Newer vehicles increasingly use electric power steering (EPS), which uses a motor rather than hydraulic fluid — simpler in some respects, but with its own failure modes.
Warning Signs of Power Steering Problems
- Heavy or stiff steering — especially at low speeds or when parking
- Whining or groaning noise when turning (hydraulic systems) — usually indicates low fluid or a failing pump
- Jerky steering response — inconsistent assistance
- Power steering warning light — primarily in EPS-equipped vehicles
- Steering wheel vibrating or feeling loose
- Fluid leak — power steering fluid is typically clear to light brown and found near the pump or rack
Common Hydraulic Power Steering Problems
- Low fluid level — check the reservoir under the bonnet; low fluid often indicates a leak
- Failing power steering pump — the most common HPS failure; causes noise and loss of assist
- Rack and pinion leak — the steering rack develops a leak, causing loss of fluid and assist
- Power steering hose leak — high-pressure hoses crack with age
Common Electric Power Steering Problems
- EPS motor failure — rare but expensive
- Torque sensor failure — the sensor that reads steering input malfunctions
- Software/ECU fault — sometimes resolved by a software update from the dealer
- Wiring fault — corrosion or damaged connectors affecting the EPS motor
Can You Drive With Power Steering Problems?
You can physically drive without power steering — vehicles were driven without it for decades. But it's harder work, especially at low speeds, and if there's an underlying fault, the condition will likely worsen. Don't ignore a power steering warning light or progressive loss of assist.
Power Steering Repair Costs in Perth
- Fluid top-up and leak inspection — $50–$100
- Power steering pump replacement — $400–$900 parts and labour
- Steering rack replacement — $600–$1,500+
- EPS motor replacement — $500–$1,200 (varies significantly by vehicle)
Book a Power Steering Inspection in Perth
If your steering is feeling heavier than usual or you're hearing unfamiliar noises when turning, have it inspected before the problem progresses. A failing power steering pump or rack leak won't repair itself, and the cost generally increases the longer you leave it.
