A Guide to the 2006-2012 Mitsubishi Eclipse Power Steering Pump
If your steering is getting noisy or stiff, your power steering pump may be the problem.
- Whining noises and a stiff steering wheel are the most common signs of a failing pump.
- No major recalls exist for the pump itself, but always inspect hoses for leaks first.
- A new aftermarket pump is often a more reliable choice than a remanufactured one.
- Properly bleeding the system after installation is critical to the new pump's lifespan.
Is Your Eclipse Power Steering Pump Failing?
The power steering pump is a hardworking part in your Eclipse. It runs anytime the engine is on. Over time, seals can wear out and internal parts can fail. This leads to common symptoms that tell you it's time for a replacement.
Common Failure Symptoms
- Whining or Groaning Noises: A common sign of a failing pump is a whining noise that gets louder when you turn the steering wheel. This is often caused by low fluid or air in the system, but can also mean the pump itself is wearing out.
- Stiff Steering Wheel: If turning the wheel suddenly requires a lot of muscle, especially at slow speeds, the pump is likely not providing enough pressure.
- Fluid Leaks: You might see reddish or brownish fluid puddles under the front of your car. While leaks can come from hoses, the pump itself can also leak from its seals or housing.
- Vibrating Steering Wheel: A steering wheel that vibrates, especially when idling, can indicate a problem with the pump.
Check Your Hoses First
Before replacing the pump, always inspect the power steering hoses. Old, cracked, or loose hoses can cause leaks and let air into the system, creating symptoms that mimic a bad pump. Replacing a hose is much cheaper and easier than replacing the entire pump.
Choosing the Right Aftermarket Power Steering Pump
When shopping for a new aftermarket power steering pump for your 2006-2012 Eclipse, you have several options. The quality can vary, so it's important to understand the differences.
Brand Quality Tiers
- Standard Tier (Cardone, BBB Industries): These are some of the most common brands in the aftermarket. They offer both new and remanufactured pumps. Forum discussions and reviews are often mixed; some users have great success, while others report issues with remanufactured units failing early. If choosing one of these brands, a 'new' unit is generally a safer bet than a 'remanufactured' one for better reliability.
- Value Tier (Mapco, other private labels): These brands offer a more budget-friendly price point. While they meet basic fitment requirements, there is less long-term reliability data available from Eclipse owners specifically. They can be a good choice if cost is your primary concern, but may not have the same lifespan as a higher-tier part.
Pro Tip: New vs. Remanufactured
A 'new' aftermarket pump is made with all-new components. A 'remanufactured' pump uses the original housing (the core) but is rebuilt with new seals, bearings, and other internal wear items. While remanufacturing saves resources and can be cheaper, the quality depends heavily on the rebuilder's process. For a critical part like a power steering pump, a new unit often provides more peace of mind and a longer warranty.
Power Steering Pump Replacement Cost for 2006-2012 Mitsubishi Eclipse

| New Aftermarket Pump | $116 - $311 |
| Shop Labor | $170 - $250 |

Frequently Asked Questions (FAQ)
Are there any recalls on the 2006-2012 Eclipse power steering pump?
No. There are no active recalls or widespread Technical Service Bulletins (TSBs) from Mitsubishi specifically for power steering pump failure on the 2006-2012 Eclipse. Always check for leaks from the power steering hoses, as that is a more common and less expensive failure point.
Can I replace the power steering pump myself?
Yes, this is a DIY-feasible job for someone with moderate mechanical experience. The process involves draining the fluid, removing the serpentine belt, disconnecting the high-pressure and return lines, and unbolting the pump. Access can be tight, especially on the V6 model. The most critical step is properly bleeding the air out of the system after installation to prevent noise and damage to the new pump.
What kind of power steering fluid does the Eclipse use?
Always check your owner's manual for the exact specification. Most Mitsubishi vehicles of this era use a specific power steering fluid or a compatible high-quality synthetic multi-vehicle power steering fluid. Do not use generic automatic transmission fluid (ATF) unless it is explicitly stated as compatible by the fluid manufacturer for your vehicle.
Do I need to replace the pulley?
Most new aftermarket pumps for the Eclipse do not come with a new pulley. You will need to carefully remove the pulley from your old pump and transfer it to the new one. This may require a special pulley puller/installer tool, which can often be rented from auto parts stores.
