Yes, you can still drive a car with a failing power steering pump, but be aware that steering will be much harder, especially at low speeds, and you should limit driving and get the issue diagnosed and repaired promptly.
Power steering systems rely on either a hydraulic pump or an electric motor to provide steering assist. A failing pump in hydraulic systems reduces assist and can cause noise, leaks, or stiffness in steering. In electric power steering (EPS) setups, the issue may present differently, often tied to electronic controls rather than a fluid pump. The overview below covers signs, safety considerations, and steps to take.
What the power steering pump does
The power steering pump circulates hydraulic fluid under pressure to help the steering rack or gearbox move with less effort. When the pump fails, there is less or no assist, making steering heavier and harder to control, particularly at low speeds when you’re maneuvering in parking lots or turning from a standstill.
Hydraulic vs electric power steering
Most older and many current vehicles use hydraulic power steering that depends on a belt-driven pump. Newer cars may use electric power steering (EPS), which uses an electric motor rather than a fluid pump. If your car uses EPS, a "bad pump" issue may not apply in the same way, and the fault may be an electronic control issue or motor failure. Check your owner’s manual or a trusted mechanic to identify the system type in your car.
Symptom signs of a failing power steering pump
Before a full failure, you’ll often notice one or more of these indicators that point to a pump problem. Watch for changes in steering feel and unusual noises or leaks.
- Stiff or heavy steering, especially at low speeds.
- Whining, groaning, or squealing noises from the engine bay when turning.
- Low or leaking power steering fluid, often with red, brown, or clear fluid near hoses or the pump.
- Difficulty keeping the steering wheel centered or consistent steering effort.
- A visible serpentine belt wear or tension issue affecting the pump’s drive belt.
Driving with these symptoms can be risky, as steering effort may spike or fail suddenly, making evasive maneuvers harder and increasing the chance of an accident.
Is it safe to drive with a bad power steering pump?
The short answer is: not recommended for extended driving. A malfunctioning hydraulic pump reduces steering assist, making steering heavier and slower to respond. In intense traffic or emergency maneuvers, the extra effort can compromise safety. If the system completely fails while driving, you may lose your power assist, but you can still steer manually—though it will be significantly harder, especially at low speeds. If your car uses electric power steering, the consequences differ and may involve a warning light or motor fault rather than a pump failure.
What to do if you suspect a bad power steering pump
If you notice warning signs or suspect a failure, take these steps to protect yourself and your vehicle.
- Check the power steering fluid level and look for leaks; if fluid is low, top up only with the manufacturer-recommended fluid and diagnose the leak promptly.
- Inspect the drive belt for cracks, wear, or looseness that could affect the pump’s operation.
- Avoid long trips or high-stress driving until the issue is diagnosed and repaired.
- Have a qualified mechanic diagnose the system; the pump, hoses, rack, or seals may need replacement, or the issue could be electronic in EPS systems.
Addressing a failing pump promptly reduces the risk of sudden steering loss and prevents collateral damage to the engine belt or steering components.
Costs and options
Repair costs vary depending on the vehicle, whether the pump can be replaced alone or requires related components, and your location. Typical hydraulic pump replacement may involve labor charges and the pump itself. For EPS systems, diagnostics may pinpoint an electrical motor or control module failure rather than a pump replacement. Always obtain a written estimate and consider getting a second opinion if the diagnosis is unclear.
Summary
In short, you can technically drive with a failing power steering pump, but it is not advisable to drive far or in heavy traffic. Expect much heavier steering, potential belt issues, and possible loss of assist. If you notice symptoms, stop when safe, check for leaks and fluid level, and have the system inspected by a professional as soon as possible. Prioritize safety and avoid driving through demanding conditions until the problem is resolved.
How much does it usually cost to fix a power steering pump?
between $500 and $900
On average, replacing your power steering pump can cost between $500 and $900, but it's essential to avoid more serious damage to the power steering system. Replacing the pump yourself can save you about $300 and significantly lower the total cost of this repair.
Can AutoZone check power steering?
Power steering makes your steering wheel easy to turn and helps you control your vehicle. If you're having issues with the system, stop into an AutoZone for help diagnosing the problem, or check for one of these issues.
How long can you drive with a bad steering pump?
Operating with a power steering pump that has no fluid in it can likely cause the pump to fail in a few minutes. One won't be able to cover even the first hundred miles with a dried power steering pump. Without the fluid, the power steering pump or rack can overheat, leading to complete failure of the system.
Does Grease Monkey change power steering fluid?
Grease Monkey provides fluid exchange services for critical vehicle systems, including engine oil, transmission fluid, coolant (radiator fluid), brake fluid, and power steering fluid.
