When it comes to maintaining your vehicle's optimal performance and ensuring a safe driving experience, tyre alignment is a crucial, yet often overlooked, aspect of car care. Many drivers understand the importance of regular tyre rotations and balancing, but the intricacies of wheel alignment, particularly four-wheel alignment, can be a bit more mysterious. This is where reputable tyre and auto service centres, like Merityre, come into play. Many customers often ponder the specific services offered by their local garages, and a common query is: "Does Merityre do 4-wheel alignment?" This article aims to demystify the process of four-wheel alignment and shed light on whether Merityre is a provider of this essential service.
What is Wheel Alignment?
Wheel alignment, often referred to as tracking, is the process of adjusting your vehicle's suspension components so that your wheels are set to the correct angles. These angles determine how your tyres make contact with the road. The primary goal is to ensure that all four wheels are perpendicular to the ground and parallel to each other. Proper alignment is vital for several reasons:
- Tyre Wear: Misaligned wheels can cause uneven and accelerated tyre wear, leading to premature replacement and increased costs.
- Fuel Efficiency: When your wheels are misaligned, your engine has to work harder to move the car, resulting in increased fuel consumption.
- Handling and Steering: Proper alignment ensures your vehicle drives straight and true, improving steering response and stability, especially at higher speeds.
- Safety: Misaligned wheels can affect your car's ability to steer accurately, potentially compromising your safety and the safety of others on the road.
Understanding the Different Types of Alignment
There are typically two main types of wheel alignment services:
Two-Wheel Alignment (Front-End Alignment)
This is the more basic form of alignment and focuses solely on the front wheels of the vehicle. It adjusts the toe, camber, and caster angles of the front wheels. While common, it doesn't address potential issues with the rear wheels, which can also contribute to handling problems and uneven tyre wear.
Four-Wheel Alignment
This is a more comprehensive service that adjusts the alignment angles for all four wheels. It is particularly important for vehicles that have adjustable rear suspensions or for those experiencing issues with both front and rear wheel alignment. A four-wheel alignment ensures that all wheels are aligned with each other and with the vehicle's chassis, providing the most accurate and effective correction for alignment problems.

When Do You Need a 4-Wheel Alignment?
Several signs can indicate that your vehicle's wheel alignment needs checking and potentially adjusting. Being aware of these symptoms can help you prevent further damage and maintain a safe drive:
- Uneven Tyre Wear: This is perhaps the most tell-tale sign. Look for feathering (edges of the tread worn smooth), cupping (scalloped or circular patterns), or wear on only one side of the tyre.
- Vehicle Pulling to One Side: If your car consistently drifts to the left or right when you're driving on a straight and level road, it's a strong indication of misalignment.
- Crooked Steering Wheel: If your steering wheel is off-centre when driving straight, your alignment is likely out of sync.
- Loose or Wandering Steering: The steering might feel imprecise, or the car may feel like it's wandering across the road, requiring constant small steering corrections.
- Squealing Tyres: Tyres can squeal during cornering if they are not properly aligned, even at low speeds.
- After an Incident: If you've hit a kerb, a pothole, or been involved in a minor accident, it's wise to get your alignment checked, as these events can easily knock your wheels out of alignment.
- New Tyres: It's good practice to have your alignment checked when fitting new tyres to ensure you get the maximum lifespan out of them.
The Four-Wheel Alignment Process
A professional four-wheel alignment service typically involves the following steps:
- Initial Inspection: The technician will first inspect your tyres for wear patterns and check for any damage to the suspension or steering components. They will also check tyre pressures.
- Vehicle Data Input: The specific make, model, and year of your vehicle are entered into the alignment machine. This provides the technician with the manufacturer's recommended alignment specifications.
- Sensor Attachment: Electronic sensors (or targets) are attached to each wheel.
- Alignment Measurement: The vehicle is driven slightly onto a platform, or the sensors are moved around the vehicle, and the alignment machine measures the current angles of your wheels relative to the vehicle's chassis and the road. Key measurements include:
- Toe: The angle of the wheels when viewed from above. If the front of the wheels are turned slightly inwards, it's 'toe-in'; if they're turned slightly outwards, it's 'toe-out'.
- Camber: The angle of the wheels when viewed from the front. If the top of the wheel is tilted outwards, it's positive camber; inwards, it's negative camber.
- Caster: The angle of the steering axis when viewed from the side. It affects steering stability.
- Setback: The difference in the distance from the centre line of the vehicle to the centre of the front and rear wheels on the same side.
- Included Angle: The sum of the individual camber and steering axis inclination (SAI) angles.
- Adjustments: Based on the measurements and the manufacturer's specifications, the technician will make adjustments to the suspension components (such as tie rods, control arms, and camber bolts) to bring all angles within the correct range.
- Final Check: After adjustments are made, the alignment is measured again to ensure all specifications are met. The technician will then remove the sensors and check tyre pressures.
