Power Steering

Power Steering Components for steering systems and axles

In this section of our specialized catalog for Steering and axles, we offer a technical range of spare parts focused on power steering for heavy-duty vehicles. These components are essential to assist wheel movement through hydraulic pressure, dramatically reducing the physical effort required to control trucks and buses.

Our offering is aimed at professional workshops and fleet managers who require reliable spare parts for corrective maintenance. Here you will find critical elements such as pumps, steering boxes and reservoirs, designed to withstand high workloads and ensure precise maneuverability of the industrial vehicle.

Criteria for selecting power steering spare parts

• OEM reference: Check the original part number to ensure geometric and functional compatibility with the rest of the steering system.
• Pressure and flow specifications: Make sure the pump or component meets the pressure in bar and liters per minute required by your model’s hydraulic circuit.
• Vehicle type and application: Confirm that the spare part is suitable for the tonnage and specific use (urban, long-haul or construction), as material fatigue varies.
• Fluid compatibility: Check what type of hydraulic oil the component requires to avoid damage to internal seals and gaskets.
• Auxiliary elements: Consider whether you also need to replace the drive belts or the reservoir filters for a complete repair.

Frequently asked questions

What are the main symptoms of a power steering failure?

The most common signs in heavy-duty vehicles include excessive stiffness in the steering wheel, noises or humming when turning the steering (especially when cold) and visible hydraulic fluid leaks. An imprecise response or vibrations in the steering may also be noticed.

How do I identify the exact spare part for my industrial vehicle?

The most accurate option is to find the reference stamped on the old part (OEM number) or consult the technical data sheet with the chassis number (VIN). Steering and axle systems have very specific configurations depending on the truck’s year and series.

Is it necessary to change the hydraulic oil when installing a new part?

Yes, it is standard practice in professional mechanics. Old fluid often contains metal particles and dirt that can immediately damage the new component. The circuit should be cleaned, the filter replaced and new fluid added with the correct specification.

What preventive maintenance does the power steering system require?

It is recommended to periodically check the level in the expansion reservoir, visually inspect the hoses for cracks or leaks, and check the tension of the belt that drives the pump. Proper maintenance extends the service life of the entire steering assembly.
