Heavy-duty trucks are relied upon across many industries and are known for their durability, but like any other vehicle, they are prone to mechanical problems. One of the most critical components of your heavy-duty vehicle is the steering system. A malfunctioning steering system can cause accidents and put the operator’s life at risk. In this article, we will discuss the three common indications of steering problems in heavy-duty trucks and their possible causes.
Hard Steering
Hard steering is when the driver has to apply excessive force to turn the steering wheel. There are several possible causes of hard steering. The first is a low power steering fluid level. The power steering system uses hydraulic pressure to make turning the steering wheel easier. If the power steering fluid level is low, the system won't function properly, making it harder to steer the truck. In some cases, air bubbles can also form in the power steering system, causing hard steering.
Another possible cause of hard steering is a faulty power steering pump. The power steering pump is responsible for pumping the power steering fluid through the system. If the pump is faulty, it won't be able to generate enough hydraulic pressure, resulting in hard steering. Lastly, a worn-out steering gear or linkage can also cause hard steering. If the gears or linkage are worn out, they won't be able to transfer the force from the steering wheel to the wheels, making it harder to turn.
Loose Steering
Loose steering is another common indication of steering problems in heavy-duty trucks. It occurs when the driver can turn the steering wheel without applying much force, but the wheels don't respond immediately or smoothly. There are several possible causes of loose steering such as worn-out ball joints. Ball joints connect the steering linkage to the wheels. If the ball joints are worn out, they won't be able to provide a smooth and stable connection, resulting in loose steering. Worn-out wheel bearings can also cause loose steering. Wheel bearings allow the wheels to rotate smoothly. If the bearings are worn out, the wheels won't be able to turn smoothly, resulting in loose steering.
Vibrations
Vibrations are a clear indication of steering problems in heavy-duty trucks. They occur when the steering wheel vibrates or shakes while driving. There are several possible causes of vibrations. The most common is worn-out tires. If the tires are worn out or not properly balanced, they can cause vibrations. Another possible cause of vibrations is a misaligned suspension system. If the suspension system is misaligned, it can cause the wheels to vibrate, resulting in steering wheel vibrations.
Final words
If you experience any of the indications of steering problems discussed in this article, it is essential to have the truck inspected by a qualified mechanic. The causes of steering problems can vary, but timely identification and repair can prevent accidents and save lives.
