Wheel Alignment: How Often Should It Be Done?

Ensuring your vehicle's wheels are correctly aligned is a crucial aspect of regular car maintenance. It might not be as glamorous as a fresh coat of paint or a roaring engine, but the benefits of proper wheel alignment are significant, impacting everything from your car's handling and safety to its fuel economy and the longevity of your tyres. So, how often should you be thinking about getting your wheel alignment checked? Let's delve into the specifics.

Understanding Wheel Alignment

Before we discuss frequency, it's essential to understand what wheel alignment actually is. In simple terms, wheel alignment refers to the adjustment of your vehicle's suspension components so that the wheels are set to the correct angles. These angles dictate how your wheels interact with the road surface. The key angles involved are:

• Toe: This refers to the angle of the wheels when viewed from above. If the front of the wheels are pointing inwards, it's called 'toe-in'. If they're pointing outwards, it's 'toe-out'.
• Camber: This is the inward or outward tilt of the wheels when viewed from the front. Negative camber means the top of the wheel is tilted inwards, while positive camber means it's tilted outwards.
• Caster: This is the angle of the steering axis when viewed from the side. It affects the steering stability of the vehicle.

When these angles are off, it's known as a misalignment, and it can lead to a host of problems. The goal of a wheel alignment is to restore these angles to the manufacturer's specifications.

Recommended Frequency for Wheel Alignment

The question of "how often" is where opinions can sometimes vary slightly. However, a widely accepted recommendation from many automotive experts is to have your wheel alignment checked every 6,000 miles or at least twice per year. This general guideline aims to catch potential issues before they become significant problems.

Another common suggestion is to consider a wheel alignment every time you replace your tyres. This is a sensible approach because new tyres are a significant investment, and ensuring they are fitted with properly aligned wheels will maximise their lifespan and performance.

However, it's crucial to understand that tyres can lose their alignment much sooner than these regular intervals. Several factors can knock your wheels out of alignment, and these can occur at any time. Therefore, being aware of the signs of misalignment is just as important as adhering to a schedule.

Factors That Can Cause Misalignment

Your vehicle's suspension system is complex and can be affected by various everyday occurrences. Here are some common culprits that can lead to wheel misalignment:

• Hitting Potholes or Kerbs: This is perhaps the most common cause. A forceful impact with a pothole or mounting a kerb, even at low speeds, can easily jolt suspension components and alter wheel angles.
• Worn Suspension Components: Over time, parts like ball joints, tie rods, and bushings can wear out. This wear can introduce play and looseness in the suspension, leading to misalignment.
• Accidents or Collisions: Even minor bumps or fender-benders can affect suspension geometry.
• Aggressive Driving: Frequent hard braking, sharp cornering, and rapid acceleration can put extra stress on the suspension system.
• Uneven Tyre Wear: While uneven tyre wear is often a symptom of misalignment, it can also contribute to it. If one tyre is significantly worn, it can affect the handling and alignment of the axle.
• Springs Sagging: If your vehicle's springs sag due to age or heavy loads, it can alter the ride height and, consequently, the wheel alignment.

Signs That Your Wheel Alignment Needs Checking

Don't wait for your scheduled check-up if you notice any of these warning signs. Addressing misalignment promptly can prevent further damage and ensure your safety:

• Uneven Tyre Wear: This is a classic indicator. Look for excessive wear on the inside or outside edges of your tyres, or a feathered pattern across the tread.
• Car Pulling to One Side: If your vehicle consistently drifts to the left or right when you're driving on a straight, level road, it's a strong sign of misalignment. You might find yourself constantly having to correct the steering.
• Vibrating Steering Wheel: A shaky or vibrating steering wheel, especially when driving at higher speeds, can be a symptom of unbalanced wheels or, indeed, misalignment.
• Crooked Steering Wheel: If your steering wheel isn't centred when you're driving straight, it's a clear visual cue that something is amiss.
• Squealing Tyres: Tyres that squeal unexpectedly during turns, even at moderate speeds, can indicate that they are not rolling in the correct direction due to misalignment.

The Benefits of Proper Wheel Alignment

Investing in regular wheel alignment checks offers several tangible benefits:

What to Expect During a Wheel Alignment Service

When you take your car for a wheel alignment, a qualified technician will use specialised equipment to measure and adjust the angles of your wheels. The process typically involves:

1. Inspection: The technician will first inspect your tyres for wear patterns and check your suspension and steering components for any damage or wear.
2. Measurement: Using a laser or camera-based alignment rack, the technician will measure the current angles of your wheels (toe, camber, and caster).
3. Adjustment: Based on the manufacturer's specifications, the technician will make precise adjustments to the suspension components, such as tie rods and control arms, to bring the wheels back into alignment.
4. Final Check: After the adjustments, the technician will re-measure the angles to ensure they are within the correct parameters.

A typical wheel alignment service usually takes between 45 minutes to an hour to complete.

Common Misconceptions About Wheel Alignment

There are a few common misunderstandings about wheel alignment that are worth clarifying:

• "It's the same as wheel balancing." Wheel balancing addresses the weight distribution of a tyre and wheel assembly to prevent vibrations. Wheel alignment addresses the angles of the wheels themselves. Both are important for tyre and driving performance.
• "My car drives fine, so alignment isn't needed." As mentioned, subtle misalignments might not be immediately obvious but can still cause gradual tyre wear and affect fuel efficiency over time.
• "Only happens after an accident." While accidents are a major cause, everyday driving hazards like potholes can easily cause misalignment.

Frequently Asked Questions (FAQs)

Q1: How much does a wheel alignment typically cost?

The cost of a wheel alignment can vary depending on your location, the type of vehicle, and the garage you choose. However, a standard front-wheel alignment might cost between £50 and £100, while a four-wheel alignment could range from £80 to £150. It's always best to get a quote from your local garage.

Q2: Can I check my wheel alignment myself?

While you can look for obvious signs like a crooked steering wheel or uneven tyre wear, you cannot accurately check or adjust wheel alignment without specialised equipment. It's a job best left to the professionals.

Q3: Will a wheel alignment fix my steering wheel vibration?

A steering wheel vibration can be caused by several issues, including unbalanced wheels or worn suspension components. While misalignment can sometimes contribute to vibrations, it's not always the sole cause. If you experience vibrations, it's best to have a mechanic diagnose the problem.

Q4: How long does a wheel alignment last?

The duration of a wheel alignment's effectiveness depends heavily on your driving habits and the road conditions you encounter. While a recent alignment should ideally last until your next scheduled check-up or tyre replacement, hitting a significant pothole can knock it out of alignment much sooner.

Conclusion

In summary, while a general recommendation for wheel alignment is every 6,000 miles or twice a year, staying vigilant for the signs of misalignment is paramount. By being aware of the factors that can cause alignment issues and understanding the indicators, you can ensure your vehicle remains safe, efficient, and comfortable to drive. Regularly checking your wheel alignment is a small investment that pays significant dividends in the long run, protecting your tyres, your wallet, and your peace of mind on the road.
