The truck steering gearbox, also known as the power steering box, plays a crucial role in the steering system, helping drivers control the vehicle smoothly and accurately, especially with heavy-duty trucks. However, after a long period of operation, the steering gearbox may experience damage, directly affecting the driving experience and operational safety. This article from Xe Tải Mỹ Đình will provide detailed information about truck steering gearbox repair, from identifying signs and repair procedures to trusted service locations for your peace of mind.
What is a Truck Steering Gearbox and Why Should You Care About Repairs?
The truck steering gearbox is the central part of the power steering system, which amplifies the force from the steering wheel, making it easier for the driver to turn the vehicle without excessive effort. A smoothly operating steering gearbox ensures stability and control, especially important when the truck is carrying heavy loads or traveling on rough terrain.
When the steering gearbox malfunctions, controlling the vehicle becomes difficult, heavy, and even potentially dangerous, leading to a loss of control. Therefore, early detection of signs of damage and timely truck steering gearbox repair are essential.

Signs You Need Truck Steering Gearbox Repair
To be proactive in maintenance and repair, you need to understand the warning signs of a truck steering gearbox issue:
Heavy, Difficult Steering Wheel
This is the most common sign of a steering gearbox problem. You will feel the steering wheel is heavier than normal, especially when steering at low speeds or when the vehicle is stopped. This may be due to insufficient power steering fluid, a weak power steering pump, or mechanical parts inside the steering gearbox being worn or stuck.
Unusual Noises When Steering
If you hear squealing, clicking, or humming noises from the steering system when turning the steering wheel, it may be a sign that the steering gearbox needs inspection. The noise may originate from the power steering pump, control valve, or dry or corroded joints.
Power Steering Fluid Leaks
Power steering fluid is essential for the efficient operation of the steering gearbox. If you notice oil stains under the vehicle, especially near the steering gearbox, or the power steering fluid level in the reservoir drops quickly, the steering system is likely leaking. Oil leaks not only cause fluid loss but also reduce power assist pressure, affecting steering capability.
Loose, Play in Steering Wheel
A loose steering wheel, slow return, or failure to return to the original position is also a notable sign. This phenomenon can be caused by worn steering tie rod ends, loose steering bushings, or worn gears inside the steering gearbox, causing delay and loss of accuracy when steering.
