TOYOTA HILUX REVO ROCCO GUN125 GUN126 FORTUNER GUN156 GUN165 1GD 2GD 2.4L 2.8L D-4D HYDRAULIC POWER STEERING PUMP P/STG PUMP (44310-0K130 / 443100K130 / 44320-0K130)

Overview

The Toyota Hilux Revo 1GD / 2GD Hydraulic Power Steering Pump (P/STG Pump Assembly 44310-0K130 / 443100K130) is a commercial-grade hydraulic steering component engineered specifically for Toyota Hilux Revo, Hilux Revo Rocco, and Fortuner commercial utility 4x4 / 4x2 transport vehicles powered by Toyota 2GD-FTV (2.4L) and 1GD-FTV (2.8L) D-4D VN Turbo diesel engines (Hilux Revo GUN125, GUN126, GUN135, GUN136, and Fortuner GUN156, GUN165 series equipped with hydraulic rack-and-pinion power steering systems). Driven by the engine serpentine accessory belt, this precision vane pump delivers steady, calibrated 90-bar hydraulic pressure directly to the steering rack. Replacing a worn, whining, stiff, or leaking power steering pump eliminates heavy steering effort, cures steering wheel vibration and judder at engine idle RPM, prevents fluid aeration and foaming, and restores smooth, responsive steering control under heavy commercial payload haulage and rugged off-road conditions.

Engineered to commercial fleet specifications verified against Malaysian commercial 4x4 and light commercial transport standards for dependable workshop replacement, steering system overhaul, and preventive fleet maintenance.
