Steering box
The steering gear is the central component of the steering system. It transforms the steering wheel’s rotation into linear motion at the wheels — enabling precise control and safe handling.
The steering gear, also known as the steering box, connects the steering wheel to the steering linkage, translating rotary input into lateral wheel movement. Depending on the vehicle, the system may be mechanical, hydraulic, or a combination of both.
In heavy-duty trucks and buses, steering gears often feature hydraulic power assist. A power steering pump provides the pressure needed to reduce steering effort and enhance maneuverability — even under load or when stationary.
A well-functioning steering gear provides smooth, responsive handling, minimizes steering play, and helps maintain straight-line stability. Symptoms of wear include oil leaks, imprecise steering, or delayed wheel response — signaling the need for replacement or repair.
