Steering Column Troubles: Signs, Causes & Costs

The steering column is truly the unsung hero of your car’s control system, silently translating your hand movements into the precise direction you want to go. It’s a component often taken for granted until, that is, it starts to fail. When a steering column begins to malfunction, what was once an easy, intuitive drive can quickly transform into a challenging and potentially dangerous experience.

Recognising the signs of a failing steering column isn’t merely about maintaining your car; it’s fundamentally about ensuring the safety of you and your passengers. Ignoring these indicators can lead to severe handling issues and, in the worst-case scenario, a loss of control. Keep reading as we delve into how this vital component works, explore the most common symptoms indicating your steering column might be in trouble, and discuss what you can expect if a replacement becomes necessary, including its crucial role in your vehicle's MOT Test.

How the Steering Column Works

At its simplest, the steering column serves as the crucial link connecting your steering wheel to the rest of your car’s intricate steering system. When you turn the wheel, the column efficiently transfers that rotational force down to the steering gear, which then, through a series of linkages, moves the road wheels. This seemingly straightforward process is vital for directing your vehicle.

The core of the steering column consists of a long shaft that extends from directly behind the steering wheel down to the steering gear. This shaft is typically constructed from two or more sections, cleverly connected by universal joints. These joints are not just for flexibility; they are designed to allow the column to collapse or telescope in the event of a frontal collision, a critical safety feature engineered to protect the driver from serious injury.

Modern steering columns are far more than just a mechanical shaft; they are integrated hubs for various additional components. The ignition switch, for instance, is frequently located on the column, as are the essential controls for your turn signals, windscreen wipers, and in many automatic vehicles, even the gear selector. Furthermore, many columns incorporate a sophisticated tilting or telescoping mechanism, enabling drivers to adjust the steering wheel position for optimal comfort and control, ensuring a tailored driving experience.

The column works in seamless conjunction with the power steering system. This system, whether hydraulic or electric, provides crucial assistance, significantly reducing the effort required to turn the wheels, a benefit particularly noticeable when the vehicle is stationary or moving at low speeds. Without this assistance, manoeuvring a modern vehicle would be a strenuous task.

Recognising Steering Column Faults: Top Symptoms

A malfunctioning steering column can severely compromise your ability to control your vehicle, presenting significant safety risks. Identifying problems early on is paramount. Here are some common indicators that your steering column may require immediate attention:

1) Steering Wheel Not Centred

A properly functioning steering wheel should naturally return to its centred position after you complete a turn. This self-centering action is a fundamental aspect of your vehicle’s power steering system and overall alignment. However, if you notice that your steering wheel consistently remains tilted or off-centre when you are driving in a straight line, it could well indicate a problem with your steering column.

This issue might initially be subtle, with the wheel only slightly askew, but it often has the potential to worsen over time. An off-centre steering wheel doesn't just impact your driving comfort; it can also lead to uneven tyre wear, compromised vehicle handling, and increased strain on other steering and suspension components. While this symptom can also be caused by alignment issues, a thorough inspection is crucial to pinpoint the exact cause and ensure proper repair.

2) Unusual Noises While Steering

Do you hear strange or unsettling sounds when you turn your steering wheel? If so, it’s a clear sign that something is amiss within your steering system. These noises can manifest in various ways, from subtle clicks and squeaks to more pronounced grinding, clunks, or groans. They frequently arise due to worn or damaged components within the steering column itself, such as bearings, bushings, or universal joints.

The sounds might be more noticeable when making sharp turns, especially at low speeds, or when the steering wheel is turned to its full lock position. Initially, these noises might be intermittent and easy to overlook. However, as the underlying issue progresses, the sounds typically become louder, more frequent, and more insistent. Ignoring these auditory warnings can lead to more severe steering problems and potentially more costly repairs down the line.

3) Steering Wheel Tilt Malfunction

Most modern vehicles on today’s roads feature a tilt and/or telescopic steering wheel, a convenience that allows drivers to adjust the wheel’s angle and distance for optimal comfort, ergonomic positioning, and precise control. This versatile feature relies on specific mechanisms and components housed within the steering column to function correctly and securely.

If you observe that your steering wheel no longer stays firmly in place after adjustment, or if it feels noticeably loose and wobbles while you are driving, you likely have a steering column issue related to its adjustment mechanism. A malfunctioning tilt mechanism can make driving not only uncomfortable but potentially dangerous, as an unstable steering wheel directly affects your ability to control the vehicle accurately and confidently. In some cases, the tilt function may become completely non-operational, locking the wheel frustratingly in one fixed position.

4) Hard to Turn Steering Wheel

Power steering is engineered to make turning your vehicle’s wheels almost effortless, particularly at low speeds or when stationary. If you find yourself struggling significantly to turn the steering wheel, or if it feels unusually stiff, heavy, and resistant, your steering column could be the primary source of the problem. This increased effort can be tiring and alarming, especially in situations requiring quick manoeuvres.

You may first notice the issue as a consistent “heaviness” in the steering, or it could become more pronounced when you first start your vehicle or when performing parking manoeuvres. In some cases, the difficulty might progressively increase as you turn the wheel further from the centre position. While this symptom can also be caused by problems with the power steering system itself, such as low fluid levels, a failing pump, or a faulty power steering rack, issues within the steering column can produce very similar effects, necessitating a thorough diagnosis.

5) Steering Wheel Vibration

If you notice your steering wheel vibrating or shaking, especially when driving at certain speeds or when making turns, it could be an indication of a problem with your steering column. This vibration might manifest as a subtle tremor or a more pronounced, insistent shaking, and its intensity can vary depending on your speed, road surface, or steering angle.

While wheel balance issues, misaligned wheels, or tyre problems are often the most likely causes of steering wheel vibration, steering column-related vibrations are also a possibility. When originating from the steering column, the vibration often feels more directly pronounced in your hands and arms, rather than just a general vehicle shake. The vibration might be caused by worn bearings, loose components, or misalignment within the steering column assembly itself. In some cases, this vibration may be accompanied by unusual noises, further pointing to an internal issue.

6) Warning Lights on the Dashboard

Modern vehicles are equipped with sophisticated sensors and complex computer systems that constantly monitor various components, including the intricate steering system. If your steering column develops a significant problem, it is highly likely that it will trigger one or more warning lights on your dashboard, alerting you to a potential issue.

The most common indicator directly related to steering is the power steering warning light, which typically looks like a steering wheel symbol, often accompanied by an exclamation mark, or the letters “EPS” (for Electric Power Steering). However, issues stemming from the steering column can also activate other interconnected warnings, such as the stability control (ESC) or Anti-lock Braking System (ABS) lights, as these systems often share information and rely on accurate steering input. In some instances, you might even see a general “Check Engine” light illuminate.

While these warning lights can be triggered by a wide array of issues, when they appear in conjunction with other steering-related symptoms described above, they often strongly point to a problem with the steering column or its directly associated components. One thing is clear and cannot be stressed enough: never ignore these warning lights; they are crucial safety indicators.

7) Contamination in the Steering System

Your vehicle’s steering system, including the steering column, operates in a challenging environment, constantly exposed to varying temperatures, moisture, and road debris. Over time, contaminants such as dirt, dust, grime, and tiny worn metal particles can accumulate within the system’s delicate mechanisms. This gradual buildup can lead to increased friction within the steering column, potentially causing stiffness, unusual noises, or erratic and unpredictable steering behaviour.

Regular maintenance, which includes periodic inspection and appropriate lubrication of steering components, can significantly help prevent this issue and prolong the life of your steering column. However, if significant contamination does occur and becomes a problem, it may necessitate a thorough cleaning of the affected parts or, in more severe cases, the complete replacement of damaged components within the column.

Common Causes of Steering Column Failure

Understanding what commonly leads to steering column problems can help you prevent issues and recognise them early, potentially saving you from more extensive repairs. Here are some of the most common causes of steering column failure:

Wear and Tear

Like all mechanical components in a vehicle, steering columns are inherently subject to wear and tear over time. The constant movement, rotational forces, and various stresses placed on the column’s internal bearings, bushings, universal joints, and other moving parts can lead to a gradual and inevitable deterioration. This natural wear process can be significantly accelerated by frequent driving, especially in challenging conditions such as rough roads, uneven terrain, or regular participation in high-performance driving events like autocross or track days, which place exceptional demands on the steering system.

Impact Damage

Accidents, even seemingly minor ones, can inflict significant impact damage on the steering column. A front-end collision, for instance, can compress, bend, or misalign the column, while side impacts can also cause subtle but damaging shifts. Sometimes, this damage isn’t immediately apparent and might only lead to noticeable problems months or even years down the line. Even hitting a large pothole or striking a kerb with considerable force can potentially cause damage to the steering column or its associated components, highlighting the importance of cautious driving.

Lack of Maintenance

Neglecting routine checks and the proper lubrication of steering components can regrettably lead to premature wear and ultimately, the failure of your steering column. Over time, the lubricants designed to reduce friction can break down, degrade, or become contaminated with debris. This degradation leads to increased friction between moving parts within the column, causing accelerated wear, excessive heat, and potential damage to critical internal mechanisms. Regular preventative maintenance is key to prolonging its lifespan.

Electrical Problems

While not a concern many decades ago, many modern steering columns incorporate a variety of sophisticated electrical components. These include sensors, wiring harnesses, and control modules for features such as adjustable steering, steering wheel controls, and even integrated safety systems. Electrical faults, such as short circuits, frayed wiring, or faulty sensors, can lead to malfunctions in these complex systems, adversely affecting the overall performance and reliability of the steering column. A simple electrical glitch can sometimes mimic a mechanical failure.

Manufacturing Defects

Though relatively uncommon in the vast majority of vehicles, some steering column failures can occasionally be traced back to inherent manufacturing defects. These issues might not immediately present themselves and could remain dormant until the vehicle has been in use for some time, sometimes thousands of miles. In cases of widespread defects affecting a specific model or production batch, manufacturers typically issue formal recalls to address the problem. During a recall, the steering column will usually be repaired or completely replaced at no charge to the owner, typically through an authorised local dealership.

Steering Column Replacement: What to Expect

When it comes to the cost of replacing a steering column, it’s important to understand that the expenditure typically falls anywhere from approximately £800 to £1,200. This range can fluctuate significantly based on various factors. The cost for the steering column part itself will vary; a used part might be as low as £100, while a brand-new, genuine part could range from £400 to £500, or even more for certain premium vehicles.

However, the labour is often what will constitute the largest portion of the total cost for replacing the steering column. This isn't a quick job; it will take more than just a couple of hours for a skilled mechanic to carefully remove your old steering column and then meticulously install and calibrate the new one. For this reason, the labour charges alone will typically range anywhere from £300 to £600.

The exact cost ultimately depends on the specific make and model of your vehicle, as well as how complicated or time-consuming it is for the mechanic to access and replace your particular steering column assembly. Some vehicles require significant disassembly of the dashboard or other interior components, which naturally increases the labour time and, consequently, the overall cost.

The Steering Column and Your MOT Test: A Critical Safety Check

The steering column, along with the entire steering and suspension system, undergoes rigorous scrutiny during your annual MOT Test. Correct assessment of the condition of these components is arguably one of the most challenging parts of the MOT Test, especially given the very prescriptive process for carrying out the required checks. This can easily lead to Testers struggling to make correct decisions or, more critically, failing to spot potentially dangerous defects.

Why the MOT Test is Crucial for Steering & Suspension

The MOT Test is designed to ensure vehicles meet minimum road safety and environmental standards. Steering and suspension are fundamental to a vehicle's safe operation. A failure in these systems can lead to loss of control, making accurate and thorough testing paramount for road safety. The complexity of modern suspension and steering layouts means Testers must be highly vigilant.

Key Inspection Areas for the Steering Column

During the MOT, specific attention is paid to the steering column. It is crucial to ensure that the condition of the lower steering column mounting is thoroughly checked. This area, often located in the driver’s footwell, can sometimes be obscured by shields, but Testers are still required to get their head down with an inspection lamp to assess the condition of both the lower coupling and the mounting. It's important to note that excessive play in the LOWER steering column bush is NOT a reason for failure; only the upper bearing or bush is testable for excessive play. Small amounts of wear or movement are generally not reasons for rejection, and the 'pass and advise' maxim is often applied where there’s subjective doubt about excessive play.

Assessing Steering Wheel Free Play

Free play at the steering wheel is a clearly defined aspect of the MOT Test. On a standard steering layout, Testers should expect no more than 75mm of free play at the circumference of the steering wheel for non-rack and pinion systems. For steering rack layouts, this allowance is significantly tighter, at no more than 13mm. If there are multiple universal joints in the column on a rack system, this allowance is extended to a maximum of 48mm at the circumference of a standard 380mm wheel. This table summarises the limits:

MOT Inspection Procedures: A Deep Dive

The process for checking the steering and suspension systems during an MOT will vary depending on the layout of the MOT bay and the vehicle type. Testing on a pit with conventional equipment will necessarily differ somewhat from testing on a ramp equipped with wheel play detectors.

Ramps with Raised Grease or Turn Plates

For test stations using ramps with raised grease or turn plates, the recommended procedure often involves checking the rear suspension first. This is because jacking up the front first and then lowering the vehicle onto the turn plates can create instability when attempting to jack up the rear, potentially risking the vehicle running off the plates. By jacking the rear first, the necessary checks to the rear suspension can be conducted safely, and an assistant is not always required unless visibility is poor or play is detected and its source needs pinpointing. Once rear checks are done, the car can be safely chocked with the handbrake applied for the front end inspection.

Wheel Play Detectors

Bays fitted with wheel play detectors offer another method. It’s important to also check the rear suspension while operating the detectors in side-to-side mode, as this can reveal excessive play in rear suspension components (e.g., BMW upper rear suspension mountings) that are difficult to check by other methods. While opinions on their effectiveness vary among Testers, in practice, if wheel play detectors are used properly, the results should be consistent with conventional methods.

Jacking the Front Suspension Correctly

A common area where incorrect testing methods occur is during front suspension checks while the vehicle is jacked up. This often happens because Testers don't correctly identify the suspension layout before jacking the vehicle, leading to inspection of joints that are under load, where wear cannot be accurately detected. The basic rule is: if the suspension load acts directly on the lower suspension component, then the vehicle should be jacked up under that arm. If the load is borne by the upper suspension component or if a MacPherson strut is fitted, then the suspension should be allowed to hang. Failure to follow this rule can lead to excessive wear being missed, particularly in upper arm bushes or ball joints on certain layouts (e.g., Audi, Volkswagen, Honda types) or lower ball joints/bushes on others. This has critical road safety significance, as evidenced by past issues like the Ford Transit lower ball joint weakness.

The Assistant's Role: Push and Pull Checks

For non-ATL (Automated Test Lane) or OPTL (One Person Test Lane) equipment, five distinct front suspension checks are required using an assistant. All five checks should first be completed by the Tester and then repeated by the assistant while the Tester examines the relevant components for wear. These include:

1. With the vehicle jacked up, the Tester (and then assistant) grasps the wheel at 9 o’clock and 3 o’clock, shaking it to detect free play in steering components.
2. The Tester (and then assistant) shakes the wheel at 12 o’clock and 6 o’clock, checking for wear in suspension joints/bushes and wheel bearings.
3. Still with the vehicle jacked up, the Tester (and then assistant) levers upwards under the road wheel (using a bar at least 24 inches long) whilst checking for play in ball joints, top strut mountings, and the strut itself.
4. With the vehicle lowered onto unlocked turn plates, the Tester (and then assistant) should grasp the wheel at the top and push and pull “vigorously” in and out, checking by ‘feel’ for free play.
5. The Tester (and then assistant) should grasp the wheel at 9 o’clock and 3 o’clock again, shaking vigorously checking for free play.

Note that using a bar under the wheel and vigorously rocking on turn plates are not required if ‘shaker plates’ are available. The check where the assistant rocks the steering with the front wheels on a solid surface is replaced on an ATL or OPTL by using the wheel play detectors in rotational mode.

Using Turn Plates Effectively

The final two checks that are sometimes missed or incorrectly performed also involve the turn plates. There is a requirement to check for fouling on a full lock, with the vehicle fully lowered onto the turn plates, ensuring not to bounce against the lock stops. Normally, an assistant holds the steering on a full lock during this check. While easy in a conventional bay, it's more difficult on an ATL or OPTL, sometimes requiring an assistant or tools like a brake pedal applicator or steering lock device to hold the steering. Finally, the Tester, sitting in the driver’s seat, must turn the steering slowly from lock to lock with the vehicle on the turn plates, checking for roughness and tight spots, which could indicate a bent or damaged rack. Seized or unused turn plates are a sign of poor practice and should be part of monthly Quality Control checks.

Wear Assessment: The Subjective Element

Assessing wear is often subjective, especially when specific wear limits are not provided in the manual. For instance, while Section 2.4 of the Inspection Manual gives limits for suspension pins (e.g., more than 2mm for a 12mm diameter pin), for ball joints, Section 2.2 states: “f. excessive play in ball joints Note: Play must not be regarded as excessive unless it is clear that replacement, repair or adjustment of the component is necessary.”

For rubber bushes and bonded mountings, the general rule is that they do not fail unless there is excessive movement caused by the failure of the bonding or significant deterioration of the bush. Upper suspension mountings on a suspension strut, for example, are a reason for failure if the bonding has failed. The manual also notes: “Some rubber/synthetic bushes are designed to provide a comparatively high degree of compliance. They are therefore likely to show some movement.” It’s often challenging to make correct decisions on these items, so Testers are advised to take their time, consult the manual, and apply the 'pass and advise' maxim if there is doubt as to whether a defect meets the criteria for failure.

Frequently Asked Questions (FAQs)

Is it safe to drive with a faulty steering column?

No, it is generally not safe to drive with a faulty steering column. A malfunctioning steering column can severely compromise your ability to control the vehicle, leading to unpredictable steering, increased effort, or even a sudden loss of steering control. This poses a significant risk to your safety and the safety of others on the road. It's crucial to have it inspected and repaired as soon as possible.

How often should I have my steering column inspected?

Your steering column is typically inspected as part of your annual MOT Test and during routine vehicle servicing. However, if you notice any of the symptoms mentioned in this article, such as unusual noises, stiffness, vibration, or an off-centre steering wheel, you should have it inspected by a qualified mechanic immediately, regardless of your service schedule.

Can a steering column be repaired instead of replaced?

In some cases, minor issues with a steering column, such as worn universal joints, loose fastenings, or faulty electrical components, can be repaired or individual parts replaced. However, if the main shaft is bent, fractured, or if internal mechanisms are severely damaged, a full steering column replacement is usually the safest and most reliable solution. A professional diagnosis is required to determine the best course of action.

What's the difference between steering column issues and power steering problems?

While often interconnected, steering column issues typically relate to the mechanical shaft and its associated components (bearings, joints, tilt mechanism) that physically transmit your steering input. Power steering problems, on the other hand, relate to the hydraulic or electric assistance system (pump, fluid, rack, motor) that reduces the effort required to turn the wheel. Both can lead to a stiff steering wheel, but a mechanic will diagnose the specific source of the fault.

Will a faulty steering column cause my car to fail its MOT?

Absolutely. A faulty steering column, especially one with excessive free play, unusual noises indicating significant wear, or a malfunctioning tilt mechanism that compromises control, will almost certainly cause your car to fail its MOT Test. The steering system is a critical safety component, and any significant defect will result in a dangerous classification, requiring immediate repair.

Conclusion

The steering column is an integral, yet often overlooked, component that is fundamental to the safe and effective operation of your vehicle.
