• A crucial frame alignment check, included as part of the service, to determine if your chassis is bent, twisted, or bowed. A compromised frame can severely affect handling and safety.
• If required, we offer a total axle adjustment/correction service to rectify any issues discovered during the comprehensive inspection.

The Goal: Precision and Performance

Our overarching aim is to produce a vehicle—be it a Hino, Kenworth, Toyota, Mitsubishi, or any other make of truck, trailer, bus, coach, van, 4x4, or caravan—that has been adjusted with all of its wheels correctly aligned to the centreline of the chassis. This meticulous approach means that when your vehicle travels down the road, the centreline of its chassis will be perfectly parallel to the white lines in the centre of the road, and each wheel will be pointing in the true direction of travel. Furthermore, each wheel will stand squarely on the road surface it is travelling on, ensuring maximum contact and even pressure distribution.

Achieving this level of precision delivers significant benefits:

• Reduced Tyre Costs: Evenly distributed wear significantly extends tyre life, saving you considerable expenditure on replacements.
• Increased Fuel Efficiency: When wheels are aligned correctly, there is less rolling resistance, meaning your engine doesn't have to work as hard, leading to noticeable improvements in fuel economy.
• Enhanced Safety: A correctly aligned vehicle handles predictably, reducing driver fatigue and improving responsiveness in critical situations. This contributes directly to a safer driving experience.
• Improved Comfort and Running Characteristics: A vehicle with precision alignment simply drives better, offering a smoother, more stable ride.

What is a Compact Wheel Alignment System?

The core of modern wheel alignment lies in sophisticated technology, and a compact wheel alignment system represents the pinnacle of this advancement. These systems leverage cutting-edge camera technology to deliver fast and highly accurate measurements. This makes it possible for truck and bus workshops, as well as tyre service centres, to offer wheel alignment services with unparalleled speed and precision.

Key wheel angles measured by these systems include:

• Toe: The inward or outward angle of the wheels when viewed from above.
• Steering Box Position: Ensuring the steering wheel is centred when the wheels are straight.
• Camber: The inward or outward tilt of the wheel when viewed from the front.
• Out of Square, Parallelism, and Axle Offset: Crucial measurements to ensure the axles are correctly positioned relative to each other and the chassis.
• Castor, KPI (Kingpin Inclination), Toe Out On Turns, and Max Turn: Advanced measurements that affect steering stability and cornering behaviour.

All these measurements are taken using patented camera technology, with the vehicle's chassis centreline serving as the fundamental reference point. This ensures that every adjustment contributes to the vehicle’s overall alignment with its true direction of travel.

Revolutionary Measurement Methods

One of the most innovative features of these compact systems is the unique rolling method. This allows toe and camber measurements to be taken while the vehicle remains in its normal driving position. Crucially, no lifting of the axles with run-out compensation is required, which significantly speeds up the process and reduces potential for error. Alternatively, for those who prefer, the system can also be operated with the standard run-out procedure.

Wireless technology is employed for transmitting data between the measuring units and the computer, ensuring a clean, efficient, and cable-free workspace. The intuitive computer software guides the user through the entire measuring process, and comprehensive measurement reports are generated, showing values both before and after alignment. This transparency provides clear proof of the improvements made.

Why Align Your Vehicle Wheels? The Indisputable Benefits

The decision to invest in professional wheel alignment is an economic and environmental one, with direct implications for your bottom line and the planet. By precisely measuring and adjusting wheel angles on your vehicle, you unlock a multitude of benefits:

Firstly, and perhaps most immediately noticeable, are the reductions in fuel costs and tyre wear. When wheels are out of alignment, they drag or scrub across the road surface, creating friction that wastes fuel and rapidly wears down tyre treads unevenly. Correct alignment eliminates this unnecessary resistance, allowing your vehicle to roll more freely and efficiently.

Secondly, comfort, security, and running characteristics are significantly improved. A misaligned vehicle can pull to one side, cause the steering wheel to be off-centre, or vibrate at certain speeds, leading to a less comfortable and more tiring driving experience. More critically, it compromises the vehicle's handling and stability, making it less secure, especially at higher speeds or during emergency manoeuvres. Precision alignment restores the vehicle's designed handling characteristics, making it safer and more predictable on the road.

Ultimately, these improvements lead to a better economy and environment for everyone. Reduced fuel consumption means lower emissions, contributing to a greener footprint. Extended tyre life means fewer tyres ending up in landfill. Furthermore, a correctly aligned vehicle travels on the highway without taking up as much space as an incorrectly aligned vehicle would, as it tracks perfectly straight, reducing the risk of unintentional lane drifting.

Frequently Asked Questions About Wheel Alignment

How often should I get my vehicle's wheels aligned?

While there's no strict universal rule, it's generally recommended to have your alignment checked annually or every 10,000 to 15,000 miles. However, it's crucial to get it checked sooner if you notice any signs of misalignment, hit a large pothole, curb, or are involved in a minor collision. Also, always get an alignment after replacing suspension or steering components.

What are the common signs of misaligned wheels?

Key indicators include uneven or rapid tyre wear, the vehicle pulling to one side (left or right) even on a flat road, your steering wheel not being centred when driving straight, and vibrations coming from the steering wheel or floorboards. If you experience any of these, it's time for an alignment check.

What is the difference between wheel alignment and wheel balancing?

Wheel alignment adjusts the angles of your wheels to ensure they are parallel to each other and perpendicular to the ground, relative to your vehicle's chassis. Wheel balancing, on the other hand, corrects uneven weight distribution in the tyre and wheel assembly, preventing vibrations at speed. Both are crucial for optimal performance but address different issues.

Can a vehicle's frame affect wheel alignment?

Absolutely. Our service includes a frame alignment check precisely because a bent, twisted, or bowed chassis can make proper wheel alignment impossible. If the foundation is compromised, no amount of wheel adjustment will truly resolve the issue, affecting vehicle safety and handling.

Why is the 'chassis centreline' so important for alignment?

The chassis centreline serves as the true reference point for all alignment measurements. By aligning all wheels to this central axis, we ensure that the vehicle tracks perfectly straight down the road, with all wheels pointing in the true direction of travel. This is fundamental for achieving optimal tyre wear, fuel efficiency, and safe handling, preventing the vehicle from 'crabbing' or taking up more road space than necessary.

Does wheel alignment affect my vehicle's safety?

Yes, significantly. A misaligned vehicle can have unpredictable handling, reduced stability, and longer braking distances. It can also cause premature wear on critical steering and suspension components, potentially leading to dangerous failures. Proper alignment ensures your vehicle responds as designed, enhancing your safety and that of others on the road.

Investing in professional wheel alignment, utilising advanced equipment like Josam and Biessbarth, is a fundamental aspect of responsible vehicle ownership and fleet management. It's a proactive step that pays dividends in reduced operational costs, enhanced safety, and improved driving experience, ensuring your vehicle performs at its very best, mile after reliable mile.
