Semi trucks are very important. They also break down a lot due to semi truck problems. You may wonder why that is. Well, it’s because of the amount of work they do and how often they are on the road. Hold on, before you hate on semi trucks, let me share with you two interesting facts.
- If trucks don’t work for 24 hours, hospitals will run out of food.
- If trucks make no supplies for 72 hours, stores will run out of supplies.
You see their importance now, don’t you? Now let’s identify 3 main causes for their frequent breakdowns and how you can manage them. Bear in mind that an hour a truck is parked is an hour of no profit made. So if it breaks down for a whole day, the truck owners must have incurred quite some losses. Now, when it comes to semi truck problems, understanding the root causes can make a big difference. Let’s see the causes of the breakdown .

Electrical Reasons
From your truck’s battery to the alternator to the starter motor, everything depends on the electrical system of your truck. A lot of other fixtures like your thermostat, your air conditioning, ignition, radio, lights, and starter all make use of electricity.
You should avoid putting too much load on the electrical system of your truck to prevent potential semi truck problems. Don’t make it a habit to create unnecessary comfort that weighs the system down. Know how to conserve power. For instance, you could try using LED lights as they are power-conservative. After all, you still get your lights, but they don’t suck all the power.
Avoid electrical faults as much as you can. They take a long time to be identified and some time to fix. The last thing you want is to develop an electrical fault on the go.
The Truck’s Brakes
You cannot avoid wear in brakes. They are almost always in use. This corrosion is worse when the truck is on the go for very long periods of time. The pressure on the brakes, the heat, and the friction it undergoes contribute to its wear and subsequent damage. Also, the water lines of the brakes may get clogged because of contamination.
Before you go on a supply, check the brakes to ensure it’s in good working condition. You don’t want to develop semi truck problems, especially with your truck’s brakes on the highway.
Your Truck’s Tires
It isn’t just about properly inflating your car tires; the threads matter too. If your truck has a missing thread or low thread depth, that could possibly be a big problem, especially when dealing with semi truck problems. So before you get on the road, fix them.
If it seems you’re always having issues with your truck tires, it’s important you confirm you’re using the right kind of tires for your truck.
Axle alignment is also crucial because if it is misaligned, it could cause frequent wear of your tires.
