Les Schwab Wheel Alignment Explained

Understanding Wheel Alignment at Les Schwab

Many drivers often wonder about the specifics of automotive services, and wheel alignment is one of those areas that can cause confusion. Specifically, questions arise such as "Does Les Schwab do a safety alignment?" and "What is included with a Les Schwab wheel alignment?" This article aims to demystify the process, explain the importance of proper alignment, and detail what you can expect when you visit a Les Schwab service centre for this essential maintenance task. Ensuring your vehicle's wheels are correctly aligned is paramount for safety, tyre longevity, and optimal driving performance.

What Exactly is a Wheel Alignment?

A wheel alignment, often referred to as a steering alignment or tracking, is a crucial adjustment of your vehicle's suspension components. It's about ensuring that your wheels are set to the optimal angles as specified by the vehicle manufacturer. These angles dictate how your wheels interact with the road surface. Three primary angles are adjusted during a standard alignment:

• Camber: This refers to the inward or outward tilt of the top of the tyre and wheel assembly when viewed from the front of the vehicle. Negative camber means the top of the tyre is leaning inwards, while positive camber means it's leaning outwards. Manufacturers set specific camber angles for each vehicle model to ensure proper handling and even tyre wear.
• Toe: This is the angle at which your tyres are pointing in relation to each other, viewed from above. When tyres are pointing straight ahead, they are at 'zero toe'. Toe-in means the front of the tyres are pointing slightly inwards, and toe-out means they are pointing slightly outwards. Toe is arguably the most critical angle for tyre life, as even slight misalignment can cause tyres to scrub against the road surface.
• Caster: This angle relates to the angle of the steering axis when viewed from the side of the vehicle. It affects the stability of your steering and how the wheels return to centre after a turn. Proper caster ensures stable straight-line driving and aids in steering control.

Will Misalignment Affect My Tyres?

Absolutely. Misalignment is one of the most common culprits behind premature and uneven tyre wear. If your tyres exhibit:

• Edge wear: Significant wear on the inner or outer edge of the tyre tread.
• Feathered wear: Where the tread blocks are worn more on one edge than the other, creating a 'sawtooth' pattern.

These are strong indicators that your vehicle's alignment is off. As explained, camber and toe angles are particularly influential in this regard. When camber is out of specification, it can cause excessive wear on either the inner or outer shoulder of the tyre. When toe is misaligned, the tyres are essentially being dragged or scrubbed sideways across the road with every rotation, drastically reducing their lifespan.

What is Included with a Les Schwab Wheel Alignment?

When you bring your vehicle to Les Schwab for a wheel alignment, you can typically expect a comprehensive service designed to restore your vehicle's handling and tyre wear characteristics to factory specifications. While the exact procedure might have minor variations based on the vehicle and the technician's approach, a Les Schwab alignment generally includes:

• Initial Inspection: A thorough visual inspection of your tyres, suspension, and steering components to identify any obvious damage or worn parts that could affect the alignment.
• Computerised Measurement: Using state-of-the-art alignment equipment, the technician will measure the current camber, caster, and toe angles of all four wheels. This equipment provides precise readings against the manufacturer's specified angles for your specific vehicle.
• Adjustment of Angles: Based on the measurements, the technician will adjust the relevant suspension components to bring each angle back within the manufacturer's recommended range. This often involves adjusting tie rods (for toe) and various suspension arms or eccentric bolts (for camber and caster).
• Post-Alignment Check: After the adjustments are made, the technician will re-measure all angles to confirm that they are now within specification.
• Test Drive: In many cases, a short test drive may be conducted to ensure the steering feels correct and the vehicle tracks straight.

Does Les Schwab Do a Safety Alignment?

While Les Schwab doesn't typically market a service specifically as a "safety alignment" in isolation, a standard wheel alignment performed at Les Schwab inherently addresses critical safety aspects of your vehicle. Proper wheel alignment is fundamental to:

• Stable Handling: Correct alignment ensures your vehicle steers predictably and maintains a straight path, especially at higher speeds or during emergency manoeuvres.
• Effective Braking: Properly aligned wheels contribute to more stable and controlled braking, reducing the risk of pulling to one side.
• Tyre Performance: Ensuring your tyres are making proper contact with the road enhances grip and overall vehicle control.
• Preventing Pulling: An alignment corrects issues where the vehicle may consistently pull to one side of the road, which can be a significant safety hazard, especially if the driver has to constantly fight the steering wheel.

Therefore, when you get a wheel alignment at Les Schwab, you are indeed investing in the safety of your vehicle. They focus on bringing your vehicle's alignment back to the manufacturer's specifications, which are designed with safety and optimal performance in mind.

Why is Maintaining Proper Alignment So Important?

The benefits of maintaining proper wheel alignment extend far beyond just avoiding uneven tyre wear. Consider these key advantages:

Tyre Longevity

As discussed, misalignment is a primary cause of premature tyre wear. By correcting the angles, you allow your tyres to roll more freely, significantly extending their usable life and saving you money on replacements.

Improved Fuel Efficiency

When your wheels are misaligned, they create more rolling resistance. This means your engine has to work harder to maintain speed, consuming more fuel. Correct alignment reduces this resistance, potentially leading to better miles per gallon.

Enhanced Handling and Steering

A vehicle with proper alignment will steer more precisely and predictably. You'll notice improved responsiveness, less play in the steering wheel, and a more stable feel, especially when cornering or driving at highway speeds.

Smoother Ride Quality

While suspension components are the primary drivers of ride comfort, proper alignment contributes to a smoother experience. It helps prevent vibrations and ensures the vehicle tracks straight without unnecessary corrections from the driver.

Preventing Damage to Suspension Components

While less common, severe misalignment can put undue stress on other suspension and steering parts over time. Keeping everything aligned helps maintain the integrity of these components.

Common Causes of Wheel Misalignment

Several factors can knock your vehicle's wheel alignment out of sync. Understanding these can help you identify potential issues early:

• Impacts with Road Hazards: Hitting potholes, curbs, or debris on the road is a very common cause of misalignment. The force of the impact can easily bend or shift suspension components.
• Worn Suspension Parts: Over time, components like ball joints, bushings, and control arms can wear out. This wear creates play in the system, allowing the wheels to move out of their intended positions.
• Accidents or Collisions: Even minor fender-benders can affect the alignment, especially if suspension or steering parts were involved.
• Spring Sagging: If your vehicle's springs sag or break, it can alter the vehicle's ride height and consequently affect the wheel angles.
• Improper Tyre Installation: While less frequent, incorrect installation of wheels or tyres can sometimes contribute to alignment issues.

When Should You Get Your Alignment Checked?

It's a good idea to have your wheel alignment checked periodically, even if you haven't experienced any obvious issues. Recommended times include:

• When purchasing new tyres (to ensure they wear evenly from the start).
• After any suspension or steering component replacements.
• If you've hit a significant pothole or curb.
• If you notice any of the tyre wear patterns mentioned earlier.
• If your vehicle is pulling to one side.
• If the steering wheel is off-centre when driving straight.
• As part of your regular vehicle maintenance schedule (e.g., annually or every 10,000-15,000 miles).
