What is Heavy Duty Truck Alignment?

If you’re just starting out with the big rigs and familiar with common industry terms such as But no worry!

Mach 6 Truck & Heavy Equipment Repair is on your side. Let’s explore truck alignment and the special considerations we make especially for heavy trucks.

What is truck alignment?

A truck alignment is a type of heavy-duty truck repair that involves adjusting the vehicle’s suspension to affect the contact patch of the tires.

Why is truck alignment important?

If your wheels are not aligned with the road, they will wear unevenly. This leads to premature failure, which can be extremely dangerous. Also, this uneven wear extends to the vehicle’s tires, suspension, brakes and frame, causing further damage if left unchecked.

Additionally, drivers who regularly use misaligned trucks will likely face their own challenges. Struggling with the wheel of a loaded truck is no fun, especially when faced with increased vibration at the same time.

What is the correct truck orientation?

Your tires should lie flat on the road surface and match the tread perfectly. Possibly not if any of the following dimensions are skewed.


Your tire camber refers to the inside or outside angle of your truck when viewed from the front of the vehicle. Tilting inwards wears out the outer surface of the tire, while tilting outwards wears out the inner surface faster.


If you look at your tires from above, toe-in is the angle from the center of the vehicle inwards to outwards. When inclined in both directions, the tread wears unevenly and creates a saw-tooth structure. Also, the vehicle’s performance may be affected as it pulls to one side or the other while driving.


The caster of your vehicle is the lateral angular offset of the steering axle. It can tilt toward or away from the driver and can result in heavy steering if the steering is too tight.

Remember that straightening the alignment (ie, centering each angle) is the correct method for many vehicles. However, for various specialty vehicles, including racing cars and certain heavy duty trucks, it is better to adjust the angle for superior performance, handling, or fuel economy.

What are the signs of bad alignment?

Still not sure what bad alignment looks like? No problem, just look out for the signs of premature wear above. A visual inspection may also reveal “feathers” that roughly resemble a carpet burn or road rash, but on your tires. While driving, you may also feel the steering wheel pulling in one direction or another, commonly referred to as “doglegging.”

You may also want to have your tires aligned on a schedule. In this case, it is best to base your appointments for the heavy-duty truck repair on the mileage or the age of the vehicle.
