Why do you Need to do Car Wheel Alignment and its Importance

Introduction:

Many drivers underestimate the importance of wheel alignment, often waiting until noticeable problems arise, such as uneven tire wear or steering wheel slippage. Regular maintenance checks, such as tire balancing and alignment, are essential for a smooth driving experience and long tire life. Neglecting wheel alignment can lead to costly repairs and even endanger road safety. In this article, we’ll explore what car wheel alignment is, its importance, and how it differs from tire balancing.

What is a wheel alignment?

A wheel alignment is a mechanical procedure that improves vehicle performance, safety, and efficiency. It involves adjusting caster, camber, and toe angles to maintain steering stability, promote even tire wear, and improve fuel consumption. Tire alignment requires a technician to adjust the angles of the wheels to ensure they meet the vehicle manufacturer’s specifications. This process enhances steering stability, even tire wear, and overall driving performance.

When an automotive technician performs a wheel alignment, they adjust three key angles to help achieve optimal vehicle performance: caster, toe, and camber.

• Caster: This is the forward or backward tilt of the steering axis when viewed from the side of the vehicle, affecting balance and steering stability.

• Toe: This refers to the orientation of the tires relative to each other when viewed from above, affecting the uniformity of tire wear.

• Camber: This is the inward or outward tilt of the tires when viewed from the front, which is crucial for maintaining grip when cornering.

These adjustments are similar to balancing a seesaw; each angle must be set correctly to ensure your vehicle moves smoothly and evenly. Modern wheel alignments are often performed using advanced equipment, such as 3D wheel aligners or touchless wheel aligners, which provide precise measurements so the technician can make adjustments quickly.

Two-Wheel Alignment vs. Four-Wheel Alignment

The terms “two-wheel alignment” and “four-wheel alignment” describe how many tires need to be measured and adjusted during the alignment process, depending on your vehicle’s design and the symptoms it exhibits.

Two-Wheel Alignment

A two-wheel alignment, often called a front-wheel alignment, focuses on adjusting the angle of the front wheels. This is most common on vehicles with only front-wheel steering. However, if your vehicle has rear-wheel steering, or if an inspection reveals a problem with the rear wheel alignment (despite the front wheels being correctly aligned), your technician may perform a rear-wheel alignment. This specialized adjustment is similar to a front-wheel alignment but is customized to the unique setup of the rear wheels.

Four-Wheel Alignment

For four-wheel drive vehicles, a wheel alignment aligns the front and rear wheels. Suitable for most modern vehicles with independent suspension, this method ensures coordinated operation between the front and rear wheels. Aligning all four wheels helps ensure your vehicle handles as intended, maintains straight-line stability, and reduces uneven wear on all tires.

How to perform wheel alignment?

Modern wheel alignment checks often use advanced equipment, such as 3D wheel alignment machine. This technology can accurately and in real time measure the alignment angle of each wheel, ensuring the highest accuracy. The wheel alignment check process at a professional repair shop is as follows:

• Vehicle Positioning: The vehicle to be measured is placed onto an alignment stand or lift.

• Mounting Targets: Specialized wheel clamps and targets are installed on each wheel, which are lightweight and easy to handle.

• Image Capture: A high-resolution camera scans the targets, capturing the precise three-dimensional position of each wheel.

• Vehicle Adjustment: Following the on-screen instructions, the vehicle’s forward and backward roll adjustment and steering wheel rotation are performed.

• Data Analysis: The 3D wheel aligner software compares the readings with the manufacturer’s specifications, instantly detecting deviations in camber, caster, and toe angles.

• Adjustment: Based on the resulting data, the technician adjusts suspension components, such as tie rods and control arms, to achieve correct alignment for all four wheels.

• Final Verification: A second scan confirms the adjustment results, and a printed report is generated for the repair shop and customer’s records.

Why is car wheel alignment important?

Proper wheel alignment is crucial for a number of interrelated reasons that can affect vehicle safety, tire life, handling, and fuel efficiency.

Improve vehicle safety

Misaligned wheels can cause unstable handling, especially during emergency maneuvers or braking. Proper tire alignment and balancing help ensure a smooth running vehicle, preventing vibrations and shakes that can affect driving comfort and safety.

Reduce wear on suspension components

Suspension components wear naturally over time or can become misaligned due to collisions with potholes, curbs, or minor accidents. Proper wheel alignment distributes weight evenly, reducing stress on suspension and steering components.

Extend tire life

This type of misalignment can cause uneven tire wear because specific areas of the tire are subjected to uneven pressure. This uneven wear shortens the life of the tire and can compromise vehicle safety, leading to premature tire replacement. Proper wheel alignment prevents uneven wear and allows the tire to reach its intended lifespan.

Improve fuel efficiency

Driving on unevenly worn tires can result in poor handling and make it more difficult to maintain your intended driving line. Uneven tire wear increases resistance between the tires and the road. This resistance forces the vehicle to expend more energy to maintain speed, increasing overall fuel consumption. Therefore, if wheel alignment is neglected, drivers may end up driving a less fuel-efficient vehicle.

Improve driving comfort

Additionally, unevenly worn tires can create steering wheel vibrations and increase road noise, further degrading the driving experience. A well-aligned car tracks straight without sidling, reducing driver fatigue and improving comfort.

Wheel alignment is an important part of maintaining vehicle safety, optimizing tire life, improving fuel efficiency, and preserving the vehicle’s overall drivability. Ignoring tire alignment issues can lead to a variety of negative consequences, including unsafe driving conditions, increased operating costs, and the need for more frequent tire replacements.

What is the difference between wheel alignment and tire balancing?

Although wheel alignment and tire balancing are often mentioned together, they are two different maintenance procedures with very different purposes.

wheel alignment

Wheel alignment involves adjusting the wheel angles, such as camber, caster, and toe, to meet the manufacturer’s specifications. Proper alignment helps ensure straight driving and optimal tire-to-road contact, which helps improve handling and extend tire life.

Tire balancing

Tire balancing helps ensure even weight distribution across the wheels, reducing vibration and uneven wear through precise machine adjustment. This procedure can eliminate steering wheel or seat vibrations, especially at certain speeds. Regular balancing is recommended after tire rotations, repairs, or during scheduled maintenance.

Simply put, wheel balancing and alignment are designed to extend tire life and driving performance. Tire balancing focuses on weight distribution around the wheels, ensuring smooth wheel rotation and helping to reduce vibration. Wheel alignment, on the other hand, ensures proper tire angle for proper road contact. Both are important, and regular attention to both services is essential to help maintain vehicle safety, efficiency, and driving comfort.

Conclusion

Wheel alignment is an important maintenance procedure that shouldn’t be overlooked. It’s crucial for safe driving, optimal performance, and cost savings. Whether you choose a two-wheel alignment or a four-wheel alignment, ensuring your vehicle’s correct position improves handling, extends tire life, and protects your suspension. For best results, check your wheel alignment regularly or if you notice uneven tire wear, pulling, or steering issues. Investing in a wheel alignment is an investment in your vehicle’s safety, efficiency, and longevity.
