STEERING GEARBOX. The steering gearbox is a key component of the vehicle steering system designed to convert rotational movement of the steering wheel into mechanical movement of the steering linkage and wheels. This mechanism is commonly used in vehicles equipped with worm gear or recirculating ball steering systems and is widely applied in passenger cars, SUVs and commercial vehicles. The assembly typically consists of a housing, worm shaft, sector gear, bearings, seals and connection points for steering shafts and linkages. Many steering gearboxes operate together with hydraulic or electro-hydraulic power steering systems to reduce steering effort and improve driving comfort. The gearbox converts steering wheel rotation into controlled movement of steering components, allowing precise directional control of the vehicle. Our catalog includes genuine OEM steering gearboxes, quality aftermarket replacements and inspected used units without housing damage or excessive internal play. Used parts are checked for housing integrity, seal condition and mechanical operation. Selection is performed by VIN number, steering configuration and part number. Proper replacement ensures precise steering control and safe vehicle handling.
