Some semi truck repairs are more common than others. According to Fleet Equipment Magazine, at the top of the fleet costs list are power plant expenses at 36.8%, followed by exhaust system costs at 14.9%, and brakes at 5% of total costs. That means around 20% of your costs could be on repairs alone! Keep reading to learn about more of the most common semi truck maintenance services.

Wheel Repairs

Some of the most common semi truck fixes involve the wheels. These workhorses spend a lot of time on the road, and the bearings can wear thin over time. However, wheel bearings aren't the only common type of wheel maintenance. Wheel alignment is another service that's usually necessary for a semi. A wheel alignment helps to ensure the vehicle's safe operation by minimizing the vehicle's pull.

Suspension Repairs

Leaf suspensions are another element that often needs to be serviced on a semi. Leaf spring replacements, shock absorber replacements, or reconditioning are often important semi truck fixes. The suspension is for both comfort and safety. There are a lot of reasons why these parts commonly wear out. Problems with suspension can result in a rough, shaky ride, making the truck difficult to control. Suspension problems need to be addressed as soon as possible to ensure your vehicle's safety.

Transmission Repairs

Regarding transmission upkeep, the most common service is clutch plate replacement, followed by drive shaft reconditioning and replacement. The transmission on a semi is more likely to need maintenance than the engine. A transmission that's overheating, leaking, or slamming into gear needs service. Without a fully functioning transmission, the semi isn't going anywhere.

Brake System Repairs


A leaky brake line is a very common brake system issue that requires service. Of course, regular brake maintenance is also required, which includes brake pad replacement. Brake drum replacement is another adjustment you can expect to see often. Additionally, a malfunctioning brake pedal is an issue that you may come across.

In addition to the cases above, battery problems, faulty wiring, and more can also be causes for concern on a semi. Partnering with an experienced semi truck mechanic is the best way to ensure your semi truck is ready to roll. The right mechanic can quickly diagnose the required semi truck repairs and complete them in a reasonable timeframe. Call Dalton Truck Industries today to learn more or get started with your service.
