Heavy-duty truck alignment is critical for truck suspension systems, especially for big rigs and heavy-duty trucks.
For that reason, understanding the process is critical – both for operation and safety.
But what exactly does it do? What does it look like? How can maintaining this practice affect these technologies long term?
Keep reading to learn more about heavy-duty truck alignment and how it works.
Over time, the suspension system can start to experience wear and tear. This can happen more quickly if a vehicle is being used consistently, which is often true in the case of semitrucks and heavy-duty vehicles.
Alignment is a term used to describe the adjustment of the truck’s suspension system. The suspension is connected to a vehicle’s wheels and helps allow them to travel and pivot as needed. An alignment is performed to make sure that the tires are meeting the road at the right angle.
Truck wheel alignment is not an adjustment of the wheels themselves, but of the axles and tires to ensure that the wheels are pointing straight and in the right direction.
It takes trained diesel technicians to perform heavy-duty and semitruck alignments. To begin the process, they will get the tolerances and specifications for the specific set of wheels they’re working on. They do this by looking through a database of heavy-duty vehicles.
Angles are measured on each wheel using electronic sensors These angles are then compared to the specifications that are listed for the vehicle using an alignment machine. Then, technicians will work to adjust different suspension angles. Some of these angles include:
Technicians will check these suspension angles, along with kingpin inclination, axle offset and turning radius. They’ll also do an overview of the suspension system as a whole to ensure there are no broken or overly worn parts.

There are many reasons why heavy-duty truck alignment for big rigs and other vehicles is important. One of them is to prevent irregular tire wear. Misalignment of tires can cause inner and outer tire wear, as well as the tread wearing down too quickly.
Commercial truck tires are also expensive to replace (the average cost is around $500 per tire), so maximizing the amount of time they can be used is important, especially for the financial sake of the fleet/vehicle owners. Proper commercial truck alignment can help ensure that tires are not being replaced earlier than needed.
Tires that are properly aligned can also improve performance on the road and ensure that rigs are traveling with the highest possible fuel efficiency.
Proper diesel truck alignment also prevents drivers from working harder than they need to, since it would keep the truck moving in the right direction. If they have to work harder than they need to, they can get fatigued and drive inattentively and/or recklessly. So it’s crucial that tires are properly aligned to prevent this from happening.

There are several signs that a vehicle needs alignment. The most common ones include:
Other signs include noisy steering or squealing tires. If you experience any of these issues, taking your vehicle to a trained auto or diesel technician is important so you can have the problems fixed as soon as possible.

Semitruck alignment refers to the adjustment of a truck's wheels and axles to correctly align them to the truck's centerline. This is crucial for maintaining optimal tire wear, fuel efficiency and ensuring the truck handles correctly on the road.
The frequency of wheel alignment depends on various factors, including the truck's usage and condition. However, a general rule of thumb is to get them checked every 50,000 to 60,000 miles or at least once a year.
Signs your truck wheels may be misaligned include uneven or rapid tire wear, steering wheel vibration, a steering wheel that's off center when driving straight and a vehicle that pulls to one side.
Yes, misaligned wheels can negatively affect your truck's performance by causing decreased fuel efficiency and irregular tire wear. They can also compromise safety by compromising steering control.
A professional semitruck wheel alignment ensures accurate results, extends tire life, improves fuel efficiency and enhances overall vehicle safety. All of this helps to prevent costly future repairs.
Yes, heavy-duty trucks have specific alignment requirements which differ from regular vehicles due to their larger size and the increased load they carry. These specific requirements are typically provided by the truck manufacturer.
The time it takes to align the wheels of a diesel truck varies depending on the vehicle's condition. Typically, wheel alignment for trucks can take between 2 to 4 hours.
While minor adjustments can be made yourself, it's best to hire a professional diesel technician for commercial truck wheel alignment. They have the necessary experience and specialized tools to ensure precise alignment.
Of course, you can develop these industry skills yourself! After then, with the right equipment and tools, you can take on a commercial alignment yourself.
Neglecting wheel alignment for trucks can lead to premature tire wear, decreased fuel efficiency, potential damage to other components and compromised vehicle safety.
The cost of wheel alignment for a heavy-duty truck can vary widely depending on location and the specific service provider. On average, you can expect to pay between $200 to $600.
