Is Your Power Steering Pump Failing?
A failing power steering pump in your 2001-2010 Explorer Sport Trac will give you clear warning signs. The most common symptom is a whining or groaning noise that gets louder when you turn the steering wheel and often changes pitch with engine RPM.

Choosing the Right Aftermarket Pump
When replacing the power steering pump on your Sport Trac, you have several options. While the original Motorcraft part is often considered the highest quality, many owners choose aftermarket brands for their value. It's important to understand the differences.
| Brand Tier | Brands | Typical Quality & Cost |
|---|---|---|
| OEM (Original Equipment) | Motorcraft | Highest cost, but generally considered the most reliable and quietest option with the best fit. Often remanufactured. |
| Premium Aftermarket | BBB Industries, Lares | Good quality and often a reliable alternative to OEM. These are typically remanufactured parts built to meet or exceed original specifications. |
| Standard Aftermarket | Cardone, Detroit Axle | Most budget-friendly option. Quality can be inconsistent, with some owners reporting premature noise or leaks. However, many come with lifetime warranties. |
A Note on Remanufactured Parts
Most aftermarket and even many Motorcraft pumps are "remanufactured." This means an original pump core has been rebuilt with new seals and tested. While this is a cost-effective and environmentally friendly process, quality can vary between brands. Choosing a reputable brand with a good warranty is key.
Known Issues for the Explorer Sport Trac
While there are no specific recalls for the hydraulic power steering pump on the 2001-2010 Sport Trac, some related issues are noted. A recall (07V181000) was issued for certain 2007 models for over-tightened steering gear bolts, which could cause a clunking noise. Some owners and TSBs mention a shuddering or squealing noise that could sometimes be resolved with a higher-output pump from a 4-door Explorer or by using a slightly shorter serpentine belt to increase tension. It's also critical to use the correct fluid; these trucks require MERCON V automatic transmission fluid (ATF), not standard power steering fluid.
Pro Tip: Flush The System
When you replace the pump, it is critical to flush the entire power steering system to remove old, contaminated fluid and any metal particles from the failing pump. Skipping this step can cause your new pump to fail prematurely. 🎬 See this guide on how to flush your steering system Also, ensure all air is bled from the system after installation to prevent whining noises.
Frequently Asked Questions (FAQ)
Do I need a special tool to replace the pump?
Yes. Most replacement pumps do not come with a pulley. You will need a specific power steering pump pulley puller/installer tool to safely remove the pulley from your old pump and press it onto the new one. Attempting to use a hammer or a standard gear puller will likely damage the new pump.
🎬 Watch: How to use a pulley puller and installer toolWhat fluid should I use in my Sport Trac's power steering?
Your 2001-2010 Ford Explorer Sport Trac requires MERCON V automatic transmission fluid (ATF) for its power steering system. Do NOT use generic power steering fluid, as this can damage the seals and cause system failure.
Why is my new power steering pump still whining?
If a new pump is whining, it's almost always due to air being trapped in the system. You must perform a proper bleeding procedure, which involves turning the steering wheel from lock to lock several times with the engine off, and then again with the engine on, while checking the fluid level. If the noise persists, there could be a leak, a restriction in a hose, or a defective pump.
Should I replace the hoses at the same time?
It is highly recommended. Old, brittle hoses can have internal blockages or can introduce contaminants into your new pump. Replacing the high-pressure and return lines when you replace the pump is a smart investment to ensure the longevity of your repair.
