Common RSX Power Steering Pump Symptoms

Power steering pumps typically give warning signs before complete failure.

Steering Whine

A high-pitched whining sound when turning the wheel is one of the most common symptoms.

Hard Steering

Reduced hydraulic pressure can make steering noticeably heavier.

Fluid Leaks

Worn seals may allow fluid to escape.

Steering Assist Loss

The steering may feel inconsistent or difficult during low-speed maneuvers.

Foamy Power Steering Fluid

Air entering the system can create bubbles and increase pump noise.

If left untreated, a failing pump can eventually damage other steering system components.

Includes Pulley for Easier Installation

One of the biggest benefits of this A-Premium unit is that the pulley is already included.

Benefits

• Simplified installation
• No need to transfer old pulley
• Reduced labor time
• Direct replacement convenience

Many replacement pumps require pulley removal and installation, adding additional work to the repair.

Brand-New Construction

Unlike remanufactured units, this pump is sold as:

New Component

Benefits include:

• Fresh internal seals
• New bearings
• New housing components
• Reduced wear concerns

Many enthusiasts prefer brand-new steering components when available.

Important RSX Steering Noise Fix

One of the most valuable pieces of information provided by the manufacturer involves the intake hose O-ring.

Replace the O-Ring

The power steering inlet O-ring is a notorious Honda and Acura failure point.

When it fails, it can cause:

• Pump whining
• Air intrusion
• Foamy fluid
• Erratic steering feel

Many RSX owners replace the pump only to discover the O-ring was causing much of the noise.

Replacing the O-ring during installation is strongly recommended.

Direct Replacement Design

The pump is designed to replace several OEM part numbers.

Common Replacement Numbers

• 56110-PZD-A02
• 56110-PNB-306
• 56110-PNB-A01
• 56110-PNB-A03

This allows the pump to cover numerous Honda and Acura applications.

Factory-Style Specifications

Features

• Pulley Included
• Hose Barb Inlet
• Threaded Outlet

Not Included

The existing reservoir is typically reused unless damaged.

Why Power Steering Pumps Fail

Several factors contribute to pump wear.

Old Fluid

Contaminated fluid accelerates internal wear.

Air Leaks

Faulty O-rings can introduce air into the system.

High Mileage

Bearings and seals wear naturally over time.

Low Fluid Levels

Running low on fluid can quickly damage internal components.

Regular fluid maintenance helps extend pump lifespan significantly.

Installation Considerations

When replacing the power steering pump, it’s smart to inspect:

Recommended Maintenance Items

• Power steering fluid
• Inlet O-ring
• Pressure hoses
• Return hoses
• Reservoir condition

Replacing worn supporting components can improve long-term reliability.
