TOYOTA HILUX LN166 LN106 HIACE LH112 LH172 2L 3L 5L 2.8L 3.0L 3-HOLE FLANGE GEAR DRIVEN HEAVY DUTY HYDRAULIC POWER STEERING PUMP (OE: 44320-26070 / 44320-26071 / 44320-35340 / 44320-26150)

Overview

The Toyota Hilux LN166 / Hiace 2L 3L 5L Hydraulic Power Steering Pump (P/STG Pump Assembly 44320-26070 / 44320-26071) is a commercial-grade hydraulic steering component engineered specifically for Toyota Hilux, Hiace, and light commercial transport vehicles powered by Toyota 2L (2.4L), 3L (2.8L), and 5L (3.0L) naturally aspirated diesel engines (Hilux LN166, LN106, LN145, LN167, and Hiace LH112, LH113, LH162, LH172 series 4x4 pickups, utility work trucks, panel vans, and window vans equipped with gear-driven hydraulic power steering systems). Built in the 3-Hole triangular flange mounting, direct engine gear-driven configuration, this precision hydraulic vane pump delivers steady, calibrated 80–90 bar hydraulic line pressure directly to the steering gearbox. Replacing a worn, whining, stiff, or leaking power steering pump eliminates heavy steering effort, cures steering wheel shuddering and judder at engine idle RPM, prevents fluid aeration/cavitation, and restores smooth, effortless steering control under heavy commercial payloads and rough road conditions.

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

Why Choose Our Commercial Fleet Parts?

• Calibrated High-Pressure Hydraulic Flow (80–90 bar): Precision-machined internal rotor and vanes provide continuous, smooth hydraulic assistance even at low engine idling speeds, minimizing driver fatigue during tight maneuvers.

• Induction-Hardened Drive Gear: High-grade heat-treated gear teeth resist pitting, backlash, and premature wear against the engine timing gear train.

• Reinforced 3-Hole Cast Housing: Rigid cast iron/aluminum alloy housing provides high structural stability and prevents distortion under high hydraulic pressure and engine vibration.

• Integrated Flow Control & Relief Valve: Factory-calibrated internal pressure relief valve ensures stable line pressure while preventing high-pressure line bursts during full steering lock.

• High-Grade Oil Seals: Heat- and oil-resistant internal seals prevent hydraulic steering fluid from leaking into the engine oil crankcase.

• Ready Stock & Fast Shipping: Readily stocked for quick dispatch across Peninsular and East Malaysia.
