Five Common Power Steering Problems and How to Address Them

 

A functioning power steering system is vital for safe driving on New Zealand roads. If your steering wheel feels heavy or makes strange noises, it can compromise your ability to maneuver your vehicle.

Odd vibrations, leaks under the car, or steering that doesn’t return to the centre can hint at deeper problems within the system. If those hints go ignored, you might face pump failures, damaged hoses, or worse.

To help you avoid costly mistakes, we’re going to cover five common power steering problems and how you can address them.

 

What is Power Steering?

Power steering makes driving easier by reducing the effort needed to turn the steering wheel. In older cars without this feature, turning the wheel could feel like a gym workout.

With modern technology, including hydraulic and electric setups, steering has become much smoother and more responsive. Below, we’ll explore two types of power steering systems you’re likely to encounter.

 

2 Types of Power Steering

Here are the two types of power steering that can be seen in most cars, including modern ones:

Hydraulic Steering Systems

Hydraulic power steering relies on fluid pressure to make steering easier. A pump circulates the fluid, which creates the force needed to move the steering mechanism.

As you turn the wheel, valves open and direct pressurised fluid where it’s needed, making it simpler to control the car. If you own a vehicle with hydraulic steering, routine hydraulic system checks are helpful for spotting worn hoses or leaky seals early on.

Common Hydraulic Issues:

  • Low fluid levels due to leaks
  • Damaged seals or hoses
  • Faulty pumps leading to stiff steering
  • Overheating fluid from continuous strain

Addressing these problems often involves steering fluid replacement or swapping out seals, hoses, and pumps that have seen better days. If you notice reddish or brownish fluid stains under your car, schedule repairs straight away.

 

Electric Power Steering

Electric power steering (EPS) systems do away with hydraulic pumps and use electric motors instead. When you turn the wheel, an EPS module reads your steering input and delivers assistance accordingly.

This technology reduces engine drag and frees up power that can be transmitted to the drive wheels. EPS systems typically need less maintenance, but there are still a few potential issues to keep an eye on.

Common EPS Issues:

  • Electronic glitches causing intermittent assistance
  • Faulty sensors leading to inconsistent steering
  • Motor failure that makes your steering wheel feel heavier

When you encounter such problems, you’ll likely need electric power steering help from professionals. When you bring your vehicle in, they will closely monitor it to find specific issues, check for worn parts, and ensure your EPS unit functions normally before you leave.

No matter which system you have, regular servicing is a key part of car steering maintenance. By spotting minor faults early, you can avoid major breakdowns and keep your driving experience safe and hassle-free.

 

Key Problems and Solutions

Here are five common issues that crop up in power steering systems, along with straightforward methods to address them. We’ll also highlight the importance of using expert steering technicians when necessary.

Fluid Leaks

Causes:

  • Worn hoses or seals
  • Damaged connection points
  • Excessive pressure leading to cracks

Solutions:

  • steering pump repairs or replacement of faulty hoses and seals
  • Regular hydraulic system checks to prevent leaks from going unnoticed
  • Keeping an eye on any stains under the vehicle

Leaking power steering fluid can create several follow-on problems, such as poor pump performance and eventual system failure.

Quick action is critical. If your fluid reservoir keeps dropping below the recommended level, you might have a leak. Although it’s possible to top it up yourself, keep in mind that you’ll need professional help to track down and fix the actual problem.

 

Noisy Steering

Causes:

  • Low fluid levels
  • Air trapped in the system
  • Worn or failing pump bearings

Solutions:

  • Bleed the system to remove trapped air
  • Perform steering fluid replacement using manufacturer-recommended fluid
  • Seek professional help if you suspect failing parts

When you hear whining, squealing, or groaning sounds every time you turn the wheel, it’s usually an early sign that something needs attention.

If the noise persists after topping up the fluid, it’s better to consult expert steering technicians who can do a thorough inspection.

 

Heavy Steering

Causes:

  • Failing or damaged pump
  • Old fluid that no longer provides enough lubrication
  • Lack of routine car steering maintenance

Solutions:

  • Check the pump for any visible damage
  • Replace or top up the fluid following steering system tune-up guidelines
  • Consult professionals for potential pump or belt replacements

Heavy steering requires immediate attention because it can make your vehicle harder to control, especially on winding roads or when you need to swerve suddenly. Take your car in for power steering services as soon as you feel unusual resistance.

 

Steering Wheel Vibration

Causes:

  • Misaligned wheels
  • Loose or worn-out steering components
  • Damaged tyres causing uneven grip

Solutions:

  • professional wheel alignment to correct misalignment
  • Inspect and replace worn ball joints or tie rods
  • Check tyres for damage or uneven wear

Vibration isn’t just annoying; it could signify deeper suspension or steering complications. Addressing these problems promptly can help you steer clear of expensive part replacements and hazardous driving conditions.

 

Steering Wheel Not Returning to Centre

Causes:

  • Faulty rack and pinion system
  • Damaged suspension parts
  • Misalignment that prevents full wheel return

Solutions:

  • Professional inspection for potential rack and pinion damage
  • Replacement or repairs by power steering specialists
  • Ensuring steering repair solutions are done right the first time

A steering wheel that doesn’t return to centre can catch you off guard while driving. It increases the chance of drifting into the wrong lane if you get distracted. If this happens, don’t wait. Schedule a certified auto servicing appointment to correct the issue.

 

Steering Maintenance is Simpler Than You Think

Power steering issues may seem complicated, but they become much easier to handle with timely checks and quick responses to early warning signs. Keep an ear out for odd noises, watch for puddles under your car, and track any changes in how your steering wheel feels.

If you need extra assistance, seek out power steering specialists who can evaluate every component—from your pump and hoses to the rack and pinion system. Routine car steering maintenance doesn’t have to take much time.

In fact, addressing small problems can prevent large-scale replacements down the line. A quick leak fix or a professional wheel alignment can restore your steering performance and help keep you safe on the road.

Questions to Ask

How often should power steering be serviced?

You should consider a steering system tune-up every 12 months or every 20,000 kilometres, depending on how much you drive. If you notice any unusual sounds, fluid leaks, or heavier steering, bring your car in sooner.

 

Can I fix a fluid leak myself?

It depends on your skill level and available tools. While you can top up the fluid at home, it’s best to let a professional identify the source of the leak. Hidden cracks or damaged seals often require specialist gear and experience.

 

Why is my steering wheel making a whining noise?

Whining noises often point to air in the system or low fluid levels. If you’ve topped up the fluid and the noise remains, you might have a worn pump or a more significant issue.
