Power Steering Pump Replacement and Diagnosis for 1975-1980 Dodge B300
Keep your classic Dodge van easy to steer by understanding how to spot a failing power steering pump and choose the right replacement.
- Symptoms of failure include whining noises, stiff steering, and fluid leaks.
- No specific recalls or TSBs exist for this model; issues are due to age and wear.
- Aftermarket quality, especially for remanufactured parts from brands like Cardone, can be inconsistent.
- Properly flushing the system of old fluid and bleeding air from the new pump is critical for a successful replacement.
Is Your Dodge B300 Hard to Steer?
A failing power steering pump can make driving your classic B300 a real workout. The system is relatively simple, but when the pump starts to go, you'll notice it quickly. The most common signs are new noises from under the hood, steering that feels heavy, or fluid leaking onto the ground. Ignoring these symptoms can lead to a complete loss of power assist, making the van very difficult to maneuver in tight spaces.
Key Failure Symptoms
- Whining Noise: A distinct whining or groaning sound that gets louder when you turn the steering wheel and changes pitch with engine speed is the number one sign of a problem. This is often caused by low fluid or air in the system.
- Stiff Steering: If turning the wheel suddenly requires a lot of muscle, especially when parking or at low speeds, the pump is likely not creating enough pressure.
- Fluid Leaks: Puddles of reddish or light brown fluid under the front of your van indicate a leak. The pump has seals that can wear out and leak over time.
Choosing the Right Aftermarket Pump
For a vehicle from this era, finding a new Original Equipment (OEM) pump is nearly impossible. Your realistic options are new aftermarket pumps or remanufactured pumps. Both available brands, Cardone and BBB Industries, primarily offer remanufactured units for this application.
Brand Quality: Cardone vs. BBB Industries
When shopping for a replacement pump, you will encounter two main brands in the aftermarket.
- Cardone: Cardone is a very common brand for remanufactured parts. However, owner feedback is mixed. Some users report their parts work for years without issue, while others have experienced premature failures or parts that don't fit correctly without modification. They are often the most affordable option, but quality can be inconsistent.
- BBB Industries: This brand also remanufactures pumps by cleaning them and replacing internal seals and O-rings before testing for performance. While there are fewer public reviews compared to Cardone, they are a standard choice in repair shops. They typically come with a 12-month warranty.
Pro Tip: Regardless of the brand you choose, flushing the old fluid from the entire system and replacing it with fresh, correct-spec fluid is critical. Contaminated old fluid can ruin a new pump quickly. Also, make sure to properly bleed the system of any air after installation to prevent noise and damage.
Known Issues, Recalls, and Service Bulletins
Due to the age of the 1975-1980 Dodge B300, there are no active recalls or readily available Technical Service Bulletins (TSBs) from the manufacturer for the power steering pump. Any issues you encounter will be due to the age and wear of the original components. Problems like leaks and internal wear are common for any vehicle of this vintage.

Frequently Asked Questions (FAQ)
Do I need a special tool to replace the pump?
Maybe. Some power steering pump pulleys are pressed onto the shaft and require a specific pulley puller and installer tool to remove and install without causing damage. Using a standard jaw puller can bend the pulley. Check if your replacement pump comes with a pulley already installed.
Can I just use any power steering fluid?
No. While many older vehicles used generic power steering fluid, many Chrysler/Dodge vehicles specified using Automatic Transmission Fluid (ATF). Check a service manual for your specific year. Using the wrong fluid can damage seals and the new pump. A TSB for later models specified ATF+4 fluid.
My new pump is noisy. What did I do wrong?
A noisy new pump is almost always caused by air trapped in the system. You must bleed the system properly. With the engine off, jack the front wheels off the ground and turn the steering wheel from lock to lock several times to work the air out. Check the fluid level, top off as needed, and repeat until the fluid level is stable and no more bubbles appear in the reservoir.
Should I buy a cheap remanufactured pump?
It's a gamble. Many forum users report that cheap remanufactured pumps can fail quickly. Sometimes, finding a good used OEM pump from a junkyard can be a more reliable option than a low-quality remanufactured part. If you opt for a remanufactured unit, be prepared for the possibility of needing to use the warranty.
