Is OEM power steering pump better than aftermarket?

In most cases, original-equipment (OEM) power steering pumps offer the strongest guarantee of fit, reliability, and warranty, but well-chosen aftermarket pumps can match or exceed quality at a lower cost. The best choice depends on your vehicle, budget, and how you plan to use and maintain the system.

OEM Power Steering Pumps: Pros and Considerations

Fit, specifications, and warranty

OEM pumps are designed to match your car’s exact steering system, with the original specifications for flow, pressure, and mounting. They also come with manufacturer-backed warranties and access to dealer-level service networks, which can simplify ownership and maintenance over the long term.

What you should know about OEM options:

• Exact fit and alignment with your steering rack, hoses, and pulleys


• Guaranteed hydraulic specs (flow and pressure) aligned to the vehicle


• Official warranty coverage and easy access to authorized service channels


• Availability of new or remanufactured units through the automaker’s supply chain


• Potentially higher purchase price and longer lead times in some markets

In practice, OEM pumps are the safest path when factory specs and warranty protection are priorities, particularly for cars under manufacturer warranties or with unique equipment.

Aftermarket Power Steering Pumps: Options, Value, and Risk

Value, variety, and quality variability

Aftermarket pumps span a wide range of brands and quality levels, from budget remanufactured units to high-quality, brand-name parts. They offer lower upfront costs and greater availability, which can be attractive for older vehicles or budget-conscious repairs.

Key considerations when evaluating aftermarket options:

• Significant cost savings versus OEM


• Broad availability, including remanufactured and rebuilt units


• Quality can vary by brand; some match OEM specs while others do not


• Compatibility depends on the supplier; verify flow, pressure, and mounting specifics


• Warranty terms and return policies vary widely; read the fine print

Bottom line: a reputable aftermarket pump can deliver OEM-like performance at a lower cost, but success hinges on choosing a trusted brand and verifying compatibility and warranty terms.

Practical Guidelines for Choosing

Warranty, vehicle age, and service history

For new or recently purchased vehicles, OEM parts are often the safer bet to preserve warranty coverage and resale value. For older vehicles out of warranty, a high-quality aftermarket pump can be a cost-effective alternative—provided it’s from a reputable supplier.

Brand reputation and technical specs

Prioritize brands with verifiable specifications and good remanufacturing standards. Confirm the pump’s flow rate, pressure rating, mounting pattern, and pulley compatibility with your steering rack and reservoir.

Installation, warranty, and return policy

Ask about installation guidance, core return requirements, and the warranty period. A comprehensive warranty and straightforward return process reduce long-term risk if the part fails or is incompatible.

Summary

OEM pumps are typically the safer, more predictable option for fit, performance, and warranty, making them the default choice for cars under warranty or with strict OEM specifications. High-quality aftermarket pumps can offer similar performance at lower cost, especially for older vehicles or budget-focused repairs, but they require careful brand selection and verification of compatibility and warranty terms. In all cases, pairing the pump with a healthy hydraulic system and proper installation is essential.

Is it better to use OEM or aftermarket parts?

OEM parts tend to be more expensive, but are easier to choose and usually are backed by a one-year warranty. Some aftermarket parts are equal to or better than the OEM part.

What is the lifespan of a power steering pump?

A power steering pump typically lasts for 100,000 to 150,000 miles, but its lifespan can vary significantly depending on maintenance and driving conditions. Key factors that influence longevity include maintaining clean and full power steering fluid, avoiding abuse like turning the wheel while stopped, and addressing problems early. If you hear whining or groaning noises, feel resistance when turning, or see fluid leaks, it's a good time to have the pump inspected.

Factors affecting lifespan

• Maintenance: Regularly checking and changing the power steering fluid is crucial for extending the pump's life, as old or dirty fluid can cause wear and tear. 
• Driving conditions: Vehicles driven in harsh environments with high temperatures, dust, or rough terrain put more strain on the pump, which can shorten its life. 
• Driving habits: Excessive use, such as turning the steering wheel against its stops, can accelerate wear. 

Signs of a failing pump

• Noise: Whining, groaning, or squealing sounds when turning the steering wheel. 
• Difficulty steering: A stiff or hard-to-turn steering wheel. 
• Leaks: Puddles of fluid on the ground under the front of the vehicle. 
• Delayed response: A noticeable lag when turning the steering wheel. 

Should I buy a remanufactured power steering pump?

Yes, remanufactured power steering pumps can be good, offering a more affordable and often reliable option, especially when they come from reputable brands that test thoroughly. They are a better choice than a used pump, as they are rebuilt with new parts and undergo extensive testing to meet or exceed original equipment specifications. However, quality can vary by brand, so it's important to research and ensure the manufacturer performs quality checks and testing.

Benefits of remanufactured power steering pumps

• Cost-effective: They are a cheaper alternative to a brand-new pump. 
• Environmentally friendly: The remanufacturing process requires less energy and raw materials than manufacturing a new part. 
• Improved designs: Reputable manufacturers like Cardone scrutinize original designs for potential improvements and implement upgrades to create a more durable part. 
• Rigorous testing: High-quality remanufactured pumps are often computer-tested for pressure, flow, valve operation, and noise to ensure they meet or exceed OE performance. 

What to consider before buying

• Brand reputation: The quality can vary between brands. Some brands may have more consistent quality and fewer failures than others. Researching brands known for reliability is a good idea. 
• Warranty: A pump with a warranty provides more security, but a bad experience is still possible. 
• System preparation: It is crucial to thoroughly flush the power steering system before installing any new or remanufactured pump. This removes metal particles and debris that can cause premature failure of the new pump. 
• Potential issues: Some anecdotal evidence suggests remanufactured pumps can fail quickly, particularly if the rebuilder does not check for wear in the shaft or other critical internal components.
