5 Warning Signs of a Bad Power Steering Pump
Power steering pumps are built tough, often lasting at least up to 100,000 miles. But sometimes, they can run into trouble before that.
If you ignore a failing power steering pump, it can lead to bigger problems down the road, such as reduced control of your vehicle and potentially expensive repairs.
In this blog, we will discuss common signs of a bad power steering pump. Spotting them earlier can save you a lot of hassle and keep your drives smooth and safe. Let’s get into it.
1. Unusual Noise
If your car makes a distinct whining that matches your engine’s speed (especially as you rev the engine or twist the steering wheel), it’s probably due to a faulty power steering pump. Think of it like
If you’re hearing a groaning sound, it means your steering system needs fluid. Neglecting it can cause a hefty repair bill.
Why Does it Happen?
These noises typically stem from two main issues: a low fluid level or a worn-out pump.
The power steering pump relies on a belt connected to the engine, and if this belt is loose or the pump is failing, it’ll whine or squeal. A whining noise could also be a bad bearing on another component.
On the other hand, groaning noises signal that your steering system isn’t getting enough fluid, making it harder for your car to steer.
Solution:
If the steering feels normal and the strange sounds don’t change when turning the wheels, it’s time to check other belt-driven components for issues. However, if the pump’s fluid level is fine and the noise persists, you might need a special tool to remove or install the pulley on a new pump.
If you hear persistent whining, consider whether your power steering system might have trapped air, especially after overheating.
If your power steering reservoir is separate and has a clogged screen, cleaning it might resolve the whining. But a professional mechanic’s expertise may be necessary if the strange noise continues.
2. Difficulty in Steering
If steering your vehicle feels stiff, you’re likely facing a problem with the power steering pump. This issue shows up as resistance when you try to steer or too much free play (when the steering wheel moves without turning the wheels).
Why Does it Happen?
When the pump isn’t performing as it should, it fails to supply the necessary power steering fluid, making steering effortless. As a result, you might find yourself putting extra muscle into turning the wheel.
Solution:
Eliminate potential issues with the rack and pinion system or the suspension, as these can cause steering difficulties.
However, if steering remains hard with the engine running and other components are in good shape, it’s likely a bad pump. At this point, considering a replacement of the power steering pump is advisable.
3. Fluid Leaks
Noticing your car’s power steering fluid is consistently low can be a red flag indicating a leak in your steering system.
Usually, steering should be smooth and responsive, with the front wheels reacting instantly to your direction. Keep an eye on the ground beneath your parked car for any signs of red or orange fluid — a sign of a hydraulic fluid leak.
Why Does it Happen?
Leaks usually occur because of worn-out seals within the power steering pump, leading to decreased fluid levels. It affects your steering’s responsiveness and causes damage to the pump itself. Identifying a leak earlier can prevent these issues from escalating.
Solution:
Regularly check under the hood and monitor fluid levels. If you notice the power steering fluid is always running low, or if there are puddles of reddish-brown fluid under your car, it’s a strong indication of a leak.
Check the fluid level against the minimum and maximum markers on the reservoir; it should ideally sit between these two.
Replacing the power steering pump might be necessary if you confirm a leak.
4. Foamy or Discolored Power Steering Fluid
You may find that your power steering fluid isn’t the clear red or pink it’s supposed to be but has turned grey. This discoloration is a sign of oxidation, which can happen when oxygen enters the fluid through the power steering pump.
Why Does it Happen?
Oxidation and the presence of metal flakes in your power steering fluid indicate a pump on its way out.
These metal particles, resulting from the pump wearing down, can circulate through your steering system, causing further damage and potentially leading to steering failure.
The grey color of the fluid suggests that air is entering the system, likely through holes or leaks in the steering system’s pipes, leading to oxidation.
Solution:
If the fluid has turned grey or if you spot metal flakes, it’s a clear indicator that the power steering pump needs to be replaced. In this case, the steering gear and system flush might need replacement, too.
5. Unresponsive Steering at Low Speeds
When your car’s steering feels lagging, especially at low speeds, it points toward a bad steering pump.
Why Does it Happen?
This lack of responsiveness often indicates that the power steering pump isn’t operating efficiently. It might not be circulating the power steering fluid through the system as it should, leading to a delay in the steering action. This can become a safety hazard, making it harder to navigate tight spots or react quickly to avoid obstacles.
Solution:
If your steering wheel is slow to respond or feels sluggish, particularly at low speeds, it’s time to consider replacing the power steering pump.
Preventive Maintenance Tips for Power Steering Pump
Here’s how you can keep your system running smoothly with some simple preventive maintenance steps.
1. Check Fluid Level Regularly
Check the power steering fluid level often to ensure it’s not too low and free from dirt and debris. A simple check before and after long trips and during regular oil changes can save you from the hassle of dealing with steering issues unexpectedly.
2. Change the Filter Annually
Keep your power steering system’s fluid clean by changing the filter yearly or as specified in your owner’s manual. This filter keeps contaminants out, protecting the system and reducing pump wear.
3. Regularly Flush Your Power Steering Fluid
Power steering fluid can become dirty over time, even with a good filter. A regular flush of the fluid is essential to keep your power steering system in top condition.
When you take your car in for a flush, a mechanic will drain the old fluid and then use an air compressor to remove any remnants.
4. Inspect Your Power Steering Hoses Regularly
The power steering system relies on two hoses to transport fluid: a high-pressure hose that sends fluid from the pump to the steering gear and a low-pressure hose that returns it to the tank. Over time, these hoses can wear out, leading to leaks that compromise your vehicle’s steering performance.
To prevent such issues, regularly inspect these hoses for signs of wear, such as cracking or damage. Ensure they are not rubbing against each other and that their protective coverings are intact.
5. Seek Professional Inspection
If you’ve overlooked regular maintenance on your power steering system, there is still time to address potential issues. Taking your car to a mechanic for a thorough inspection is a wise step. Although everything within the power steering system is repairable, a neglected pump might have already suffered damage and require replacement.
