How do I know if my power steering pump is going bad?
If your power steering pump is going bad, you'll likely notice some telltale signs that indicate it's time for a replacement. In this article, we'll explore the common symptoms of a failing power steering pump and provide guidance on how to diagnose the issue.
Common Symptoms of a Failing Power Steering Pump
The power steering pump is a critical component in your vehicle's steering system, responsible for providing the necessary hydraulic pressure to make steering effortless. When the pump starts to fail, you may experience the following symptoms:
- Increased Steering Effort: As the pump weakens, you'll notice that it takes more effort to turn the steering wheel, especially at low speeds or when the vehicle is stationary.
- Whining or Groaning Noises: A failing power steering pump often produces audible noises, such as whining, groaning, or even a high-pitched squeal, especially when turning the steering wheel.
- Fluid Leaks: Power steering fluid leaks around the pump or in the system can be a sign of a failing pump, as the seals and gaskets start to deteriorate.
- Steering Wheel Vibration: In some cases, a failing power steering pump can cause the steering wheel to vibrate or shake, particularly at higher speeds.
- Difficulty Turning the Steering Wheel: As the pump's performance deteriorates, you may find it increasingly difficult to turn the steering wheel, especially when the vehicle is stationary or at low speeds.
If you experience any of these symptoms, it's essential to have your vehicle inspected by a qualified mechanic to determine the root cause and address the issue before it leads to more severe problems.
Diagnosing a Failing Power Steering Pump
To diagnose a failing power steering pump, a mechanic will typically follow these steps:
- Visual Inspection: The mechanic will visually inspect the power steering pump, hoses, and connections for any signs of wear, damage, or leaks.
- Pressure Test: Using a specialized tool, the mechanic will measure the pressure output of the power steering pump to determine if it's within the manufacturer's specifications.
- Noise and Vibration Analysis: The mechanic will listen for any unusual noises or vibrations coming from the power steering system and try to pinpoint the source.
- Fluid Level and Condition Check: The mechanic will check the power steering fluid level and inspect the fluid for any signs of contamination or degradation.
Based on the findings from these diagnostic tests, the mechanic will be able to determine if the power steering pump needs to be replaced or if the issue lies elsewhere in the steering system.
If you suspect your power steering pump is failing, it's important to have it inspected and addressed promptly to avoid further damage to your vehicle's steering components and ensure safe and reliable driving.
What are the symptoms of a bad power steering pump?
Symptoms of a bad power steering pump include whining or groaning noises when turning the wheel, a stiff or difficult-to-turn steering wheel, and fluid leaks (often reddish) under the vehicle. Other signs can be a squealing noise when starting the car, vibrations in the steering wheel, and foamy or dark power steering fluid.
Common symptoms
- Noises: Whining, groaning, or squealing sounds, especially when turning the wheel or at low speeds. A high-pitched squeal upon starting the engine that goes away can also indicate a problem with the pump belt.
- Stiff steering: The steering wheel is hard to turn, requiring extra effort, particularly when parking or at lower speeds.
- Fluid leaks: Puddles of reddish or amber fluid under the front of the car, which can be caused by a damaged pump, seals, or hoses.
- Vibrations: The steering wheel feels shaky or vibrates when you are turning it or idling.
- Fluid issues: The power steering fluid looks foamy, is discolored, or has metal flakes in it, suggesting air contamination or internal wear.
- Burning smell: A burning odor from the engine bay can indicate the pump is overheating due to excessive friction or low fluid levels.
What to do
- Check the fluid: First, check the power steering fluid level. Low fluid can cause many of these symptoms, and adding the correct type of fluid may temporarily resolve them.
- Inspect the belt: Look at the accessory belt that drives the pump to ensure it is not loose or worn out.
- Consult a mechanic: If the problem persists after checking the fluid and belt, it is best to have the system inspected by a professional, as a failing pump can be unsafe to drive with.
How much does it cost to replace a power steering pump?
The average cost to replace a power steering pump is between $300 and $800, but it can range from $270 to over $1000, depending on your vehicle's make and model, labor rates, and whether you use new, used, or rebuilt parts. Labor costs typically run between $200 and $500 for the one to three hours needed for replacement.

- Parts: The price of the pump itself can vary significantly, from around $100 for a basic aftermarket part to much more for OEM or luxury vehicle parts. This can also include new power steering fluid, hoses, and potentially a pulley.
- Labor: Expect to pay between $150 and $400 for labor, depending on the mechanic's hourly rate and your vehicle's specific setup. The job typically takes one to three hours.
- Total:
- Low end: For a DIY job, the cost is limited to parts and fluids, potentially as low as $100-$200.
- Average: A professional replacement typically costs between $300 and $800, with the average being around $842–$941.
- High end: Costs can exceed $1000, particularly for luxury vehicles or if you choose a dealership for the service.
Factors that influence the cost
- Vehicle make and model: Luxury or foreign cars often have higher part costs.
- Part type: New pumps are more expensive than rebuilt or used pumps.
- Labor rates: Shop rates vary by location.
- Additional parts: Hoses, a pulley, and a new belt may also be needed and will add to the cost.
- Location of the job: Dealerships generally charge more than independent mechanics.
How to test a power steering pump?
Pressure you see it here on the gauge. It's going to jump up it's going to skyrocket. 1,400. You can develop about 1,600. PSI. You can also dead head the pump by closing.
What happens when the power steering pump goes out while driving?
A serious problem with a faulty power steering pump is steering that doesn't respond. You may turn the wheel, but your vehicle may not change direction. As you can imagine, this can put you in a very dangerous situation and might even cause an automobile accident.
