The heart of the steering transmission
The steering shaft connects the steering wheel to the steering gear and transmits the torque generated by the driver. In modern systems, it is often combined with joints that compensate for deviations in movement and flexibility between the cab and chassis. Bosch, for example, offers variable steering shafts with ball-guided tracks that operate backlash-free and allow bending angles of up to 35°.
Good interaction
For stable and delay-free steering transmission, the shaft, joints and connecting components must be precisely matched. The length, diameter, joint design and connecting elements must match the steering column, intermediate shaft and steering gear in order to avoid play, vibrations or resetting problems.

What should you look out for when buying:
Maximum precision for truck steering: steering column and drive shaft
The steering of a commercial vehicle is a complex system that does not allow any compromises in terms of safety. The steering column and the associated steering shaft act as a direct link between the driver and the road. Every movement of the steering wheel must be transmitted precisely and without play to the steering gear to ensure exact directional stability even when fully loaded. High-quality universal joints and sliders in OEM quality minimize mechanical losses and ensure a direct steering feel that provides the necessary operational safety in tough everyday logistics.
Interaction with the steering gear and maintenance instructions
All components – from the steering column to the steering gear – must be perfectly matched so that the steering forces can act optimally. The joints of the steering shaft in particular are exposed to constant vibrations and the effects of the weather. The onset of wear often manifests itself in “spongy” steering behavior or cracking noises. By using robust spare parts that have been specially developed for the high transmission torques in trucks, you can prevent consequential damage to expensive units such as the power steering pump or the actual transmission housing and ensure the longevity of your vehicle fleet.
