Does Tracking Change Tyre Alignment? Unravelled

It's a common and incredibly frustrating scenario: your car drifts to one side, requiring constant steering correction, or perhaps the steering wheel itself is off-centre even when driving straight. You take it to the garage, they perform a 'tracking' adjustment, and the problem persists, or even worsens. This situation, much like the one you've described with your Kia Cee'd, highlights a prevalent misunderstanding about what 'tracking' truly entails and the comprehensive nature of proper wheel alignment.

Understanding 'Tracking' and the Wider World of Wheel Alignment

The term 'tracking' is often used interchangeably with 'wheel alignment' in the UK, but more specifically, it traditionally refers to the adjustment of the front wheels' 'toe' angle. While crucial, toe is just one piece of a much larger puzzle. Comprehensive wheel alignment involves ensuring all four wheels are parallel to each other and perpendicular to the ground, according to the manufacturer's precise specifications. This involves adjusting several key angles:

• Toe: This is the most frequently adjusted angle and often what people mean by 'tracking'. It refers to how much the front or rear of the tyres point inwards or outwards when viewed from above. Correct toe ensures the wheels roll straight and minimises tyre scrub, which can cause rapid tyre wear.
• Camber: This is the inward or outward tilt of the tyre when viewed from the front. Negative camber means the top of the wheel tilts inwards towards the car, while positive camber means it tilts outwards. Incorrect camber can lead to uneven tyre wear across the width of the tread.
• Castor: This angle, primarily found on the front wheels, relates to the forward or backward tilt of the steering axis. It's crucial for steering stability, self-centring of the steering wheel, and cornering dynamics. Incorrect castor can cause steering wander or make the vehicle pull to one side.

When any of these angles are out of specification, it can lead to a host of issues, including the very pulling and off-centre steering you're experiencing.

Why Correct Wheel Alignment is Paramount

It might seem like a minor adjustment, but precise wheel alignment offers significant benefits:

• Enhanced Safety: A properly aligned vehicle handles predictably, allowing for precise steering control and reducing the risk of accidents, especially during emergency manoeuvres.
• Optimised Tyre Longevity: Misalignment causes uneven and premature tyre wear, forcing you to replace expensive tyres far sooner than necessary. Correct alignment ensures even contact with the road, maximising tyre life.
• Improved Fuel Efficiency: When wheels are misaligned, they create increased rolling resistance, forcing your engine to work harder. Proper alignment reduces this resistance, leading to better fuel economy.
• Superior Driving Comfort: No more fighting the steering wheel! A correctly aligned car drives straight and true, making journeys far more relaxed and enjoyable.

Your Kia Cee'd SW: A Deep Dive into the Persistent Pull

Your experience with the Kia Cee'd is a classic example of an alignment issue that hasn't been fully resolved. The fact that the car pulls left, and the steering wheel is off-centre after the front wheel adjustment, points to a few possibilities:

1. Incorrect Adjustment: The most immediate conclusion is that the initial alignment wasn't performed accurately. If the steering wheel wasn't held perfectly straight during the adjustment process, it will be off-centre once the wheels are aligned. The mechanic's admission that he 'may not have had the steering exactly straight' confirms this possibility.
2. Underlying Issues: If the alignment was performed correctly, but the pull persists, it strongly suggests there's an underlying mechanical problem that the alignment cannot correct. This could be anything from worn suspension components to a manufacturing defect in a tyre.
3. Rear Axle Misalignment: This brings us to a critical point your mechanic dismissed.

The Great Debate: Two-Wheel vs. Four-Wheel Alignment

Your mechanic's assertion that 'there is no need to adjust the back wheels on cars, they very rarely move' is, frankly, outdated and concerning for a modern vehicle like your 2012 Kia Cee'd SW. While older vehicles with solid rear axles might only require front-end alignment, virtually all modern cars, especially those with independent rear suspension (which your Cee'd likely has), require a four-wheel alignment.

Even if the rear wheels don't appear to 'move' in the same way as the steerable front wheels, their alignment angles (particularly rear toe and camber) can significantly impact how the vehicle tracks down the road. If the rear wheels are misaligned, they can cause a 'thrust angle' – essentially making the vehicle want to crab or steer from the rear, which then forces the driver to constantly correct with the front steering, leading to the pulling sensation you describe. This is why the alignment machine explicitly says '4-wheel alignment'.

Here's a comparison to illustrate the difference:

For your Cee'd, a proper four-wheel alignment is almost certainly what's needed to diagnose and correct the issue fully. If the rear wheels are out of alignment, adjusting only the front will never truly resolve the pull.

Common Culprits of Misalignment

Even if your car was perfectly aligned from the factory, everyday driving can knock it out of spec. Common causes include:

• Potholes and Kerb Strikes: Hitting a large pothole or bumping a kerb can easily bend components or shift alignment angles.
• Worn or Damaged Suspension Components: Over time, bushes, ball joints, tie rod ends, control arms, or even worn shock absorbers can develop play, leading to shifting alignment. If the mechanic didn't check for play in these parts before alignment, it's a critical oversight.
• Accidents: Even minor collisions can affect alignment.
• Replacement Parts: Installing new suspension components (like new springs, shocks, or steering rack) often necessitates a fresh alignment.

Symptoms of Misalignment You Shouldn't Ignore

Beyond the obvious steering pull, keep an eye out for these tell-tale signs that your wheels might be out of alignment:

• Uneven or Rapid Tyre Wear: Look for feathering (one side of the tread block is higher than the other), or excessive wear on just the inner or outer edge of the tyre.
• Steering Wheel Off-Centre: When driving straight on a level road, your steering wheel should be perfectly horizontal. If it's tilted, alignment is likely off.
• Vehicle Pulling or Drifting: The car consistently wants to veer to one side without steering input.
• Loose or Vague Steering: The car feels 'floaty' or less responsive to steering inputs.
• Squealing Tyres: Tyres may squeal excessively, even at low speeds or during gentle turns.

What a Thorough Alignment Process Entails

When you next take your car in, here's what a competent garage should do:

1. Pre-Inspection: Before hooking up to the alignment machine, the mechanic should perform a thorough visual and manual inspection of your suspension and steering components. They should check for worn bushes, loose ball joints, bent components, and ensure tyre pressures are correct and tyres are in good condition. If significant wear is found, these parts must be replaced *before* alignment can be effective.
2. Modern Equipment: They should use a modern four-wheel alignment system, typically laser or camera-based, which measures all four wheels simultaneously.
3. Steering Wheel Centring: Crucially, the steering wheel must be locked in a perfectly straight position before any adjustments are made. This is likely where your initial issue stemmed from.
4. Compensation for Run-out: Modern systems compensate for minor imperfections in wheel mounting or wheel run-out to ensure accurate readings.
5. Adjusting All Applicable Angles: The mechanic should adjust front and rear toe, front and rear camber (if adjustable), and castor as per the manufacturer's specifications.
6. Print-out Report: You should always be provided with a 'before and after' print-out showing the alignment readings. This allows you to verify the adjustments made.

Beyond Alignment: When the Pull Persists

If, after a proper four-wheel alignment, your car still pulls, the problem lies elsewhere. Here are other potential causes to investigate:

• Tyre Issues: A defective tyre (known as 'radial pull') can cause a car to drift. Try swapping your front tyres from left to right to see if the pull changes direction or disappears. Also, ensure all tyres are of the same make, model, and wear level, and correctly inflated.
• Brake Drag: A sticking brake caliper could be causing one wheel to drag, pulling the car to that side. Check if one wheel feels hotter than the others after a drive, or if there's an unusual smell.
• Worn Wheel Bearings: While less common for a pull, a severely worn wheel bearing could contribute to instability.
• Bent Components: If a control arm, strut, or even the subframe is bent from a previous impact, it can prevent proper alignment, even if adjustments are made.
• Steering Rack Issues: Problems within the steering rack itself can sometimes manifest as a pull or off-centre steering.

Frequently Asked Questions (FAQs)

How often should I have my wheels aligned?

It's generally recommended to have your alignment checked annually or every 12,000-15,000 miles, whichever comes first. However, you should definitely have it checked after hitting a significant pothole, curbing a wheel, after any suspension or steering component replacement, or if you notice any of the symptoms mentioned above.

Is 'tracking' the same as 'wheel alignment'?

In common UK parlance, 'tracking' is often used interchangeably with 'wheel alignment'. However, technically, 'tracking' refers primarily to the front wheel toe adjustment, whereas 'wheel alignment' is the comprehensive adjustment of all four wheels' toe, camber, and castor angles.

Do I need an alignment after replacing tyres?

While not strictly necessary every time, it's highly recommended, especially if you're replacing all four tyres or if your old tyres showed signs of uneven wear. New tyres can sometimes mask minor alignment issues, and ensuring correct alignment will maximise their lifespan and performance.

Why does my steering wheel look straight, but the car still pulls?

This can happen if the rear wheels are misaligned, causing a 'thrust angle'. The front wheels might be correctly aligned to each other, but the car is effectively 'crabbing' down the road, and you're compensating with the steering wheel without realising it. It also points to the importance of a four-wheel alignment.

Can worn suspension parts cause alignment issues?

Absolutely. Worn bushes, ball joints, tie rod ends, or even damaged springs or shock absorbers introduce play into the suspension system. This play means that even if you adjust the alignment, the angles won't hold correctly, or they will shift dynamically as you drive, leading to persistent issues.

Conclusion

Your £50 charge for 'aligning the wheels' is reasonable if the job is done correctly and comprehensively. However, the recurring issue and the mechanic's dismissal of rear wheel alignment suggest the process was either incomplete or misdiagnosed. When you return to the garage, insist on a full four-wheel alignment and request a print-out of the before and after readings. More importantly, ensure they thoroughly inspect all suspension and steering components for wear or damage *before* attempting any adjustments. A proper diagnosis and a comprehensive alignment will not only resolve your car's pulling issue but also ensure your safety, save you money on tyres, and make your driving experience far more enjoyable.
