Buying a new truck does not guarantee that your unit will last longer than a used one. If you don’t take proper care of it, how do you expect this to happen? You cannot ignore preventive maintenance and regular check-ups.

If you’ve ever been stranded in the middle of the road, you know how difficult it can be to wait for mechanical assistance when you have a full load in the rear that you need to deliver. And that’s not all; the longer your truck is idle, the more money you’ll lose.

If you are a fleet operator, you know that it is essential that you have a complete picture of the trucks involved in your company to guarantee the fulfillment of all your work objectives. That means you should know everything about the preventive maintenance requirements for trucks.

In the following International Trucks article, wetradetrucks will mention some of the main problems that affect trucks today and that fleet operators must face.

Engine overheating

Drivers and operators should be aware that cargo trucks can suffer many consequences from engine overheating. This problem could lead to a broken gasket or fuel tank-related mishap.

Regardless, over time this can lead to engine failure if the problem is not resolved. Working with a professional or having a preventative truck maintenance program is crucial in checking and addressing the signs of overheating in your units. In the long term, this can prevent failures at a critical time.

Start failure

Particularly in colder temperatures, starter failure seems to be a problem that occurs more and more often on many trucks. To determine future performance, you should review the starting mechanism during the beginning of the winter season.

The operator will likely first notice signs of problems with a starter motor. The problem will be revealed as a problem with the truck’s ignition.

As a driver, you should alert the operators if problems are connecting the key. Also, you must ensure that all non-essential components (such as the radio) are turned off during the starting phase of the engine.

Universal joint failure

Universal u-joints are required for power to be transferred to the transmission differentiator and minimize component wear; they must be kept lubricated.

If the u-joint is about to fail, you will hear a click. Another sign of impending u-joint failure may be that at higher speeds, the vehicle tends to vibrate. As soon as possible, the universal joint should be replaced.


Due to the pressure exerted on the brakes by payloads, trucks frequently experience brake system problems on a reasonably regular basis.

Some of the more common brake problems include internal water and contamination in the air supply and control system, compressor oil leakage, external contamination and corrosion, air pressure leaks, reduced brake performance, and more.

Brake failure could even occur if trucks have not received regular recommended maintenance. However, the silver lining is that if the brakes fail, the truck will only lose its performance on the affected brake. This allows the driver to stop the vehicle using all other brakes.


For your truck’s wheel to move on the road with as little friction as possible, critical components called bearings are needed. If, while driving, you hear a lot of noise coming from the tire, the bearings are probably already worn.

Other signs of bearing wear are unstable movements or jerking of the vehicle on the road. The bearings must be checked regularly to avoid the problems above.

Also, before starting each trip, it is essential to check the tire pressure. Having over-inflated or under-inflated wheels will damage the tread and cause uneven tire wear.
