J.C. Whitney REPB510402 OEM Replacement Power Steering Pump without Reservoir

The J.C. Whitney REPB510402 is an OEM replacement power steering pump designed as a direct-fit solution for BMW 3-Series vehicles. It corresponds to BMW OEM part number 32416756582, the LF-30 version hydraulic power steering pump, and replaces the discontinued original pump number 32416760034.

The power steering pump is a critical component of your vehicle's hydraulic steering system. It pressurizes and pumps hydraulic fluid through the steering system, allowing you to turn the wheels with ease — especially at low speeds. This pump uses a vane-style design driven by the engine's serpentine belt. It draws fluid from the power steering reservoir, pressurizes it, and delivers it to the steering rack, where it amplifies your steering input to move the front wheels smoothly and responsively.

Signs of a Failing Power Steering Pump:

• Heavy or stiff steering wheel, particularly at low speeds
• Grinding or whining noise from the steering system
• Reduced steering responsiveness or wheel control
• Potential damage to other steering components from inadequate fluid pressure
