Everything You Need to Know About Wheel Alignment

If you’ve ever noticed your car pulling to one side, heard unusual tire noises, or felt uneven handling while driving, it could be a sign that your vehicle’s wheel alignment is off.

While it may seem like a minor issue, improper wheel alignment can lead to a range of problems that affect not only your tires but also your vehicle’s overall performance and safety.

We’ll explore why proper wheel alignment is crucial for tire longevity, a smoother driving experience, and your car’s overall performance.

Let’s dive into how wheel alignment works, why it’s crucial, and how you can tell when your vehicle needs an alignment.

What Is Wheel Alignment and How Does It Work?

Proper wheel alignment plays a crucial role in ensuring your vehicle drives smoothly, handles properly, and maximizes tire life. While many car owners may overlook it, keeping your wheels aligned according to the manufacturer’s specifications is crucial to maintaining your vehicle’s overall health.

Different types of vehicle wheel alignment affect how your car drives and handles. The two primary types are two-wheel alignment and four-wheel alignment.

• Two-wheel alignment typically refers to the alignment of the front wheels, which is commonly performed on vehicles with a front-wheel drive system. This alignment focuses on adjusting the angles of the front wheels to ensure proper steering and handling.
• Four-wheel alignment involves adjusting the angles of all four wheels to ensure proper alignment across the entire vehicle. This type of alignment is typically done on cars with all-wheel drive or four-wheel drive, as both the front and rear wheels need to be aligned for optimal performance.

The Role of the Steering Axis and Suspension Systems

Wheel alignment isn’t just about positioning the tires. It involves adjusting the steering axis—the line around which the steering system pivots—and ensuring it is correctly aligned. This affects how the vehicle steers and how forces are distributed across the suspension and steering systems.

The suspension system is responsible for supporting the vehicle’s weight and absorbing shocks from the road. When the suspension is misaligned, it can lead to issues such as uneven tire wear, poor handling, and increased steering effort.

Alignment Measurements and Adjustments

During a wheel alignment, trained technicians use an alignment machine to measure the angles of the wheels. These angles include:

• Camber: The tilt of the wheel when viewed from the front of the vehicle. Positive camber means the top of the wheel tilts outward, while negative camber means the top tilts inward. Misaligned camber can cause uneven tire wear, especially on the inner or outer edges of the tire.
• Caster: This refers to the angle of the steering axis when viewed from the side of the vehicle. Positive caster provides more stability, while negative caster can make the car feel unstable, especially at higher speeds.
• Toe: The angle at which the tires point in relation to the centerline of the vehicle. Toe-in means the front of the tires points inward, while toe-out means they point outward. This misalignment can cause tires to wear unevenly, often resulting in increased drag and reduced fuel efficiency.

Technicians make these adjustments to bring your car’s alignment back to manufacturer specifications, ensuring the vehicle drives straight and stable without unnecessary wear on the tires.

How Misalignment Affects Your Vehicle

When your vehicle’s alignment is off, the effects may not always be immediately apparent but can have significant consequences over time. Misalignment can lead to poor handling, uneven tire wear, and increased maintenance costs. Understanding the impact of misalignment is essential for preventing damage and ensuring that your vehicle continues to perform at its best.

Uneven Tire Wear

One of the most noticeable signs of misalignment is uneven tire wear. When your vehicle’s wheels are not properly aligned, they don’t meet the road at the correct angles, causing the tires to wear down more quickly and unevenly. This not only shortens the lifespan of your tires but can also affect your vehicle’s handling and safety.

Look for these signs of uneven tire wear:

• One side of the tire is worn out more than the other.
• Tread wear on the inner or outer edges of the tire may indicate issues with positive or negative camber.
• Tires may feel rough or noisy when driving due to uneven wear.

Vehicle Pulling

If your vehicle consistently pulls to one side, even when you’re driving straight, it’s a clear indicator of misalignment. This can occur when the steering axis or caster angles are incorrect. When one wheel is angled differently from the others, it creates a force that pulls the car in one direction.

If you notice your vehicle pulling to the left or right, it’s essential to address the issue promptly. The problem may worsen over time, making your driving experience uncomfortable and unsafe.

Increased Steering Effort

Misalignment can also cause increased steering effort. This is especially noticeable when making turns or lane changes. Misaligned wheels cause an uneven distribution of forces, making it harder to steer smoothly. Not only does this make driving less comfortable, but it can also cause steering systems to wear out faster.

A properly aligned vehicle requires less effort to steer, which reduces driver fatigue and improves the driving experience.

Handling Issues

Misalignment can significantly affect vehicle handling. When the wheels are out of alignment, the car’s ability to respond to steering inputs becomes compromised. This can cause instability, particularly when navigating curves or driving at higher speeds. It may also result in loss of traction, especially on wet or uneven road surfaces.

If your car feels less responsive or harder to control, it’s time to have the alignment checked.

Vibrations or Shaking

If you notice vibrations or shaking, especially when driving on smooth, flat roads, this could indicate a wheel alignment issue. Misaligned wheels create uneven contact with the road, which can lead to vibrations in the steering wheel or the entire vehicle. These vibrations tend to worsen as the misalignment becomes more severe.

Squealing Tires

Squealing tires are another sign that your wheels may be misaligned. This noise occurs when the tires rub against the road unevenly due to improper alignment. The increased friction can cause excessive heat and wear, damaging the tires and impacting vehicle performance. If you hear this noise consistently, it’s a sign that your vehicle needs attention.

Potential Safety Risks

Improper alignment can compromise your vehicle’s overall safety. Misalignment not only affects steering performance but can also interfere with braking performance, making it harder to respond quickly in an emergency. Ensuring your vehicle’s wheels are properly aligned is a simple yet crucial step in maintaining its safety, performance, and longevity.

Factors That Affect Alignment Frequency

Certain factors may make it necessary to have your wheels aligned more frequently, including:

• Driving on rough or uneven road surfaces: If you regularly drive on poorly maintained roads, your vehicle’s alignment may become compromised more quickly due to the constant strain on the suspension and steering systems.
• Driving habits: Frequent sharp turns, quick starts, or aggressive driving can put extra stress on the alignment and lead to more frequent misalignment.
• Vehicle type: Some vehicles, especially those with a performance suspension system, may require more frequent alignment checks. In contrast, more basic cars might be less susceptible to misalignment, but still need periodic checks.

The Benefits of Regular Wheel Alignment

Getting regular wheel alignments is an essential part of vehicle maintenance. When your car’s wheels are properly aligned, it doesn’t just improve your driving experience—it also saves you money in the long run. Here’s how regular wheel alignment helps in various areas of vehicle performance:

Improved Handling

One of the most noticeable benefits of proper wheel alignment is improved handling. When your vehicle’s wheels are correctly aligned, the vehicle responds more predictably to steering inputs. Whether you’re making sharp turns, driving at higher speeds, or navigating slippery roads, proper alignment ensures your vehicle handles smoothly and consistently.

Good alignment also helps in reducing steering effort, which means less strain on the steering system. This is especially important for comfort and control when driving for long periods or in traffic.

Tire Longevity

Misalignment is one of the leading causes of uneven tire wear, which can cause your tires to wear out prematurely. When your wheels are properly aligned, the vehicle’s weight is evenly distributed across all four tires, reducing unnecessary stress on any one tire. This helps ensure that your tires wear evenly and last longer, which saves you money on replacements in the long run.

With proper alignment, you can expect to get the full lifespan out of your tires, which is typically around 40,000 to 60,000 miles for most tires, depending on the type of driving you do.

Fuel Efficiency

Misaligned wheels create friction between the tires and the road, causing your vehicle to work harder to maintain its speed. This increased friction leads to reduced fuel efficiency. By keeping your wheels properly aligned, you can reduce rolling resistance, which allows the engine to operate more efficiently. Over time, this can result in noticeable savings at the gas pump.

Proper wheel alignment can improve fuel efficiency by up to 10%, depending on the extent of the misalignment and how long it’s been affecting your vehicle.

Vehicle Performance and Safety

Proper alignment doesn’t just improve vehicle performance; it also enhances safety. Misaligned wheels can affect the stability of your car, especially when driving at higher speeds. It can also lead to unpredictable handling, making it harder to control the vehicle in emergencies.

By regularly aligning your wheels, you ensure that your vehicle is always operating at its peak, both in terms of performance and safety. This is especially important when it comes to your car’s ability to respond to sudden steering inputs, which could make all the difference in avoiding an accident.

Smoother Ride

A well-aligned vehicle provides a smoother ride. Without the vibrations caused by misalignment, your car will drive more quietly and comfortably. The smoother ride will also reduce strain on the suspension system, which can help prevent further damage to these components over time.

How Often Should You Get a Wheel Alignment?

The frequency of wheel alignments can vary depending on several factors, including your driving habits, the type of roads you drive on, and the condition of your vehicle’s suspension system. 

However, some general guidelines can help you determine how often you should have your alignment checked.

It’s generally recommended that you get a wheel alignment check every 6,000 miles or at least once a year. This is a good starting point for most vehicles, as regular checks can catch any issues before they lead to significant wear on your tires or suspension system.

In addition to the recommended mileage, there are certain circumstances where you should have an alignment check even if you haven’t reached the 6,000-mile mark. Here are some everyday situations that may indicate a need for an alignment check:

• After hitting a pothole or curb: If you’ve hit a large pothole, a curb, or any other road hazard, it can cause sudden misalignment. This can lead to uneven tire wear and affect the steering system.
• After installing new tires: New tires are a good time to get an alignment. Misalignment can cause new tires to wear unevenly from the start, shortening their lifespan.
• If you notice changes in handling or steering: If your car starts pulling to one side, the steering wheel feels off-center, or if you’re experiencing difficulty steering, it’s time to check the alignment.
• After suspension repairs: If you’ve had any work done on your vehicle’s suspension system, it’s important to have the alignment checked afterward to ensure everything is properly aligned.

The Wheel Alignment Process

During a wheel alignment, trained technicians adjust the suspension and steering systems to ensure your vehicle is properly aligned. The process involves using an alignment machine to measure the angles of the wheels and then making the necessary adjustments to ensure the vehicle drives straight and stably.

1. Inspection: The technician will inspect the vehicle’s suspension and steering systems for any wear or damage. If components are worn out, they may need to be replaced before alignment adjustments can be made.
2. Adjustment: Once the vehicle is prepared, the technician uses the alignment machine to adjust the steering axis, ensuring proper angles for smooth and even tire wear. This process restores proper handling, reduces the risk of uneven tire wear, and enhances the vehicle’s overall performance.
3. Tire Balancing: Tire balancing is often performed alongside the alignment process. It ensures that tires rotate evenly, which reduces vibrations and prevents uneven wear. Proper tire balancing and alignment together extend the life of your tires and improve ride comfort.
