Understanding Your Car's Wheel Alignment: A Comprehensive Guide

Many car owners hear terms like 'wheel alignment,' 'wheel balancing,' and 'wheel tracking' and assume they all refer to the same thing. While they all contribute to your vehicle's overall health and the longevity of your tyres, they are distinct processes. At Elite Garages, we frequently address this confusion, and this guide aims to clarify the differences, explain the importance of each, and help you identify when your vehicle might need attention.

What is four wheel alignment?
Four wheel alignment, sometimes interchanged with terms like four wheel tracking, is essential in maintaining your vehicle's optimal performance, handling and tyre health.

Wheel Alignment: The Foundation of Smooth Driving

Wheel alignment, often referred to simply as 'alignment,' is a critical service that adjusts the angles of your vehicle's wheels. These angles, dictated by your car manufacturer, ensure that your wheels are pointing in the correct direction and are perpendicular to the ground. When your wheels are properly aligned, your car will drive straight and true, minimising unnecessary stress on your tyres and steering components. Neglecting regular alignment checks can lead to premature tyre wear, which is not only costly but can also compromise your vehicle's safety, especially during braking and cornering.

Two-Wheel vs. Four-Wheel Alignment

The type of alignment your vehicle requires depends on its drivetrain and suspension system.

Two-Wheel Alignment

Historically, two-wheel alignment was more common, focusing on adjusting the front wheels. This is generally sufficient for older vehicles or those with simpler rear axle designs.

Four-Wheel Alignment

For most modern cars, including all-wheel-drive (4WD) models and many SUVs, a four-wheel alignment is recommended. This process goes a step further by adjusting not only the front wheels but also the rear wheels. This is because even on vehicles that are not 4WD, the rear wheels can still fall out of alignment due to road impacts or wear and tear. Misalignment in the rear can cause uneven tyre wear just as easily as front-wheel misalignment.

The four-wheel alignment process is more sophisticated, often involving electronic steering procedures and CCD sensors for precise measurements of angles like camber and toe. For performance or modified vehicles, specialised 'Spoiler Programs' might be activated to accommodate different body designs.

Tyre or Wheel Balancing: Ensuring Even Rotation

While alignment focuses on the direction and angles of the wheels, wheel balancing addresses the distribution of weight around the tyre and wheel assembly. When a tyre is fitted to a rim, there can be slight imbalances in weight. If left unaddressed, this imbalance causes the wheel to vibrate as it rotates, particularly at higher speeds.

Wheel balancing involves attaching small, calibrated weights to the rim of the wheel to counteract any heavy spots. Think of it like balancing a scale; if one side is heavier, you add weight to the opposite side to achieve equilibrium.

Signs you might need wheel balancing include:

  • A noticeable tyre 'wobble' at around 40-50 mph.
  • Excessive vibrations felt through the steering wheel or the car's body at higher speeds.
  • Uneven tyre wear patterns.

What is Wheel Tracking? A Look Back

The term 'wheel tracking' harks back to a time when cars primarily featured two adjustable front wheels and a fixed rear axle. In this context, 'tracking' meant ensuring the two front wheels were pointing in the correct direction and were perfectly parallel to each other. The rear wheels, being fixed, would simply follow the path set by the front.

Today, when most people ask for 'wheel tracking,' they are usually referring to what we now understand as 'wheel alignment' or, more specifically, 'four-wheel alignment,' unless they own a classic or older vehicle with a non-adjustable rear axle.

Common Causes of Wheel Misalignment

Wheel alignment is intrinsically linked to your vehicle's suspension system. Any disruption to the suspension can lead to misalignment. The primary culprits include:

Main Causes of Wheel Misalignment
CauseDescription
ImpactsSudden, forceful impacts such as hitting a deep pothole, mounting a kerb aggressively, or being involved in a road accident can knock suspension components out of their intended positions.
Wear and TearOver time, suspension springs and other components can wear out, becoming slack. Regular servicing can help identify and address this wear before it leads to significant misalignment.
ModificationsChanges to a vehicle's ride height, such as lowering or lifting kits, without a corresponding adjustment to the suspension geometry can easily lead to misalignment.

Spotting the Signs: When Your Wheels Might Be Misaligned

While checking tyre pressure is a fundamental part of car maintenance, persistent issues might indicate a need for alignment. If your tyre pressures are correct, but you notice any of the following, it's time to consider a wheel alignment check:

  1. Vehicle Pulls to One Side: If your car consistently drifts to the left or right when you're trying to drive straight, even on a level road, it's a strong indicator of misalignment.
  2. Uneven Steering Wheel: The steering wheel should be centred when the car is driving straight. If it's noticeably off-centre, this points to an alignment problem.
  3. Loose Steering: The steering might feel vague or unresponsive, requiring constant small corrections to keep the vehicle on course.
  4. Vibrating Steering Wheel: While vibrations can also be a sign of unbalanced wheels, they can sometimes be linked to alignment issues causing uneven tyre rotation.
  5. Uneven Tyre Wear: This is one of the most common and telling signs. Look for wear on the inner or outer edges of your tyres, or a feathered pattern across the tread.
  6. Tyres Consistently Squeal: If your tyres squeal during normal cornering, it suggests they are not following the intended path, indicating a potential alignment issue.

The Importance of Regular Checks

We cannot overstate the importance of incorporating regular wheel alignment checks into your vehicle's maintenance schedule. Many motorists overlook this crucial step, leading to a cascade of expensive problems. Properly aligned wheels not only ensure your vehicle is safe to drive but also contribute to significant savings in the long run by extending tyre life and improving fuel efficiency.
