Power Steering Rack vs Power Steering Pump: What's the Difference?

Power Steering Rack vs Power Steering Pump: What's the Difference? main image

For many vehicle owners, the intricacies of a car's steering system can be somewhat of a mystery. Two crucial components that often cause confusion are the power steering rack and the power steering pump. In this article, we'll demystify these essential parts, explain their functions and differences, and highlight why it's essential you understand them.

What Is a Power Steering Rack?

The power steering rack serves as the main link between your steering wheel and the wheels on the road. Essentially, it's a long, horizontal bar that houses a gear mechanism. When you turn the steering wheel, this rack moves laterally, pushing and pulling on the tie rods connected to your wheels. The 'power' aspect comes from hydraulic assistance, which significantly reduces the effort required to steer, particularly in larger vehicles like 4x4s. Without this hydraulic assistance, steering would require considerably more physical effort, especially at lower speeds or when stationary. Anyone who's driven a car from the 50s and 60s will know what an upper body workout it was to turn the wheel without hydraulic help. Try and turn your wheels while your engine is off to feel the difference for yourself.

What Is a Power Steering Pump?

A power steering pump is the auto part responsible for creating the hydraulic pressure that assists the steering rack. Typically driven by a belt that is connected to the engine, this pump continuously circulates power steering fluid through the system. As you turn the steering wheel, the pump increases pressure on one side of the rack, providing that smooth, effortless steering feel that modern drivers have come to expect. The power steering pump essentially acts as a force multiplier, making it possible to steer heavy vehicles with minimal effort.

What Is the Difference Between a Power Steering Rack & Power Steering Pump?

While these two components work together, their roles are quite separate. The power steering rack is the mechanical part directly responsible for moving your wheels left and right. It translates the rotational movement of the steering wheel into the linear motion you need to turn your wheels. The power steering pump, conversely, is the hydraulic auto part that provides the pressure needed to assist the rack's operation. It doesn't directly move the wheels but instead makes the rack's job significantly easier by reducing the effort required to turn the steering wheel.

Only Replace with the Best

When it comes to replacing your car's existing components, quality matters — particularly for your crucial suspension and steering parts. These parts bear the brunt of every pothole, speed bump, and gravel road you encounter. Inferior parts might save you a few dollars now, but they could cost you big time down the track in repairs and safety risks. High-quality parts often provide better performance, improved fuel efficiency, and a more comfortable driving experience.
