Chevrolet Impala SS Power Steering Pump Guide (1994-1996)
Address whining noises and stiff steering by understanding how to choose the right power steering pump for your Impala SS.
- Listen for whining noises and check for stiff steering, as these are the most common symptoms of failure.
- Aftermarket pumps for this vehicle are typically remanufactured; quality can vary but they are a cost-effective option.
- You will need a special pulley puller/installer tool, as the replacement pump does not come with a pulley.
- Use standard power steering fluid and flush the old fluid to protect your new pump.
Is Your Impala's Steering Trying to Tell You Something?
The 1994-1996 Impala SS, built on the GM B-body platform, is a heavy car that relies on its power steering system for easy handling. The power steering pump is the heart of this system. When it starts to fail, you'll notice it. Common symptoms are hard to ignore and can make driving unpleasant and unsafe.
Common Failure Symptoms
- Whining or Groaning Noises: A whining sound that gets louder when you turn the wheel or as engine RPMs increase is a classic sign of a failing pump. This is often caused by low fluid levels, air in the system, or internal wear.
- Stiff Steering: If turning the steering wheel suddenly feels like a workout, especially when parking or moving slowly, the pump is likely not generating enough pressure.
- Fluid Leaks: Noticing reddish or light brown fluid puddles under the front of your car is a clear sign of a leak. While hoses can also leak, the pump itself has seals that can fail over time.
- Metal Flakes in Fluid: When checking your power steering fluid, if you see shiny metal particles, it's a strong indication that the pump's internal components are grinding themselves down and failure is imminent.
Known Issues, Recalls, and Service Bulletins
For the 1994-1996 Chevrolet Impala SS, there are no specific National Highway Traffic Safety Administration (NHTSA) recalls or widespread Technical Service Bulletins (TSBs) related to the hydraulic power steering pump itself. Searches show recalls for much newer Impala models with different electronic steering systems, which do not apply to this generation.
Choosing the Right Aftermarket Replacement
When your original pump fails, you have a few options. For a vehicle of this age, a new OEM part from GM is likely unavailable or extremely expensive. The most common and practical choice is an aftermarket replacement.
Remanufactured Aftermarket Pumps (e.g., BBB Industries)
Most aftermarket power steering pumps for the Impala SS are remanufactured. This means the original unit (the core) has been rebuilt. Companies like BBB Industries disassemble the pump, clean the housing, recondition internal surfaces, and replace all wearable parts like seals and O-rings with new components that meet original specifications. The unit is then tested for leaks and performance.
The Honest Truth About Quality: The quality of remanufactured parts can be inconsistent. While many units perform flawlessly for years, others may fail prematurely. Some owner forums report positive experiences with brands like BBB Industries, citing good warranty support. However, other reports mention receiving poorly rebuilt units. This is a risk with any remanufactured part, regardless of the brand. The main benefit is a significantly lower cost compared to a new OEM part.
Pro Tip: When replacing the pump, it's a good idea to also replace the power steering fluid and inspect the high-pressure and return hoses for cracks, brittleness, or leaks. Old hoses can fail and contaminate your new pump.

Frequently Asked Questions (FAQ)
Do I need to replace the pulley?
Almost all replacement pumps for the Impala SS do not include a new pulley. The original pulley is a press-on type and must be removed from the old pump and installed onto the new one. This requires a specific power steering pump pulley puller and installer tool, which can be rented from most auto parts stores.
What kind of power steering fluid should I use?
For the 1994-1996 Impala SS, standard, non-synthetic power steering fluid is recommended. Do not use ATF (Automatic Transmission Fluid) or synthetic fluids unless specified by the part manufacturer, as this can damage the seals. Always check the recommendation for the specific pump you purchase.
Is this a difficult job to do myself?
For a DIY mechanic with some experience, this is a moderately difficult job, mainly because it requires the special pulley tool and can be messy. The process involves draining the fluid, removing the serpentine belt, disconnecting hoses, unbolting the pump, swapping the pulley, and then reinstalling everything. Afterwards, you must bleed the air from the system. Estimated time is 2-3 hours.
What does "reverse rotation" mean?
The LT1 engine in the Impala SS uses a reverse rotation water pump and power steering pump. This means the pump spins in the opposite direction of older small-block Chevy engines. It is crucial to get a pump specifically designed for the 1994-1996 B-body platform to ensure it works correctly.
