When Is It Time to Consider Power Steering Pump Repair or Replacement?
Before jumping into a rebuild or replacement, you need to confirm the power steering pump is actually the problem. Common symptoms of a failing power steering pump include:
- Whining or Groaning Noise: Especially noticeable when turning the steering wheel.
- Stiff Steering: Requires more effort to turn the wheel, especially at low speeds.
- Jerky Steering: Steering wheel may feel like it’s catching or binding.
- Fluid Leaks: Visible leaks around the pump, hoses, or reservoir.
- Foamy Power Steering Fluid: Indicates air is entering the system.
If you notice one or more of these symptoms, inspect the power steering system. Check the fluid level and condition first. Low fluid can cause noise and stiff steering. Dark, dirty, or foamy fluid needs to be flushed and replaced. If the fluid level is good and the problem persists, further investigation is needed to determine if the pump is the culprit.
Deciding: Rebuild, Remanufacture, or Replace?
Once you’ve confirmed the power steering pump is failing, you have three main options:
- Rebuild: Replacing worn components with a power steering pump rebuild kit.
- Remanufacture: Buying a professionally rebuilt pump.
- Replace: Purchasing a new power steering pump.
Here’s a breakdown of each option:
| Option | Description | Pros | Cons |
|---|---|---|---|
| Rebuild | Repairing your existing pump using a power steering pump rebuild kit. | Least expensive option, retains original equipment, satisfying DIY project. | Requires mechanical skill, time-consuming, success not guaranteed, potential for future problems. |
| Remanufacture | Buying a pump that has been professionally rebuilt. | Less expensive than new, professionally rebuilt, comes with a warranty. | More expensive than rebuilding yourself, potential for core charge, availability may be limited. |
| Replace | Purchasing a brand new power steering pump. | Most reliable, comes with a warranty, readily available. | Most expensive option. |
Fathoming the Power Steering Pump Rebuild Process
The power steering pump rebuild process involves disassembling the pump, cleaning the parts, replacing worn seals and bearings with components from the power steering pump rebuild kit, and reassembling the pump. It is a detailed task that requires patience and a good workspace.
Here’s a general overview of the steps to rebuild a power steering pump:
- Preparation: Gather tools (sockets, wrenches, pliers, screwdrivers, seal pullers, bearing press), the power steering pump rebuild kit, a repair manual specific to your vehicle, a clean workspace, and safety glasses.
- Disassembly: Carefully disassemble the pump, noting the location and orientation of each part. Take pictures or videos to help with reassembly.
- Cleaning: Thoroughly clean all parts with solvent to remove dirt, grease, and old fluid.
- Inspection: Inspect all parts for wear or damage. Pay close attention to the shaft, housing, and vanes. If any parts are severely damaged, the pump may not be rebuildable.
- Replacement: Replace all seals, O-rings, and bearings with the new parts from the power steering pump rebuild kit. Use a bearing press to install new bearings if necessary.
- Reassembly: Reassemble the pump in the reverse order of disassembly, following the repair manual’s instructions.
- Testing: After reassembly, test the pump for leaks and proper operation before installing it in the vehicle.
Important Notes:
- Always refer to a repair manual specific to your vehicle for detailed power steering pump rebuild instructions.
- Use the correct tools to avoid damaging the pump components.
- Work in a clean environment to prevent contamination.
- Pay attention to the orientation of parts during disassembly to ensure proper reassembly.

- Remove the reservoir (if applicable) from the pump housing.
- Remove the rear cover of the pump.
- Carefully remove the internal components, such as the rotor, vanes, and flow control valve.
- Use a seal puller to remove the old seals and O-rings from the pump housing and internal components.
- Cleaning and Inspection:
- Thoroughly clean all parts with a solvent, such as brake cleaner or parts cleaner.
- Inspect the pump housing, shaft, rotor, vanes, and flow control valve for wear, damage, or corrosion.
- Check the bearings for smoothness and any signs of wear or damage.
- If any parts are severely damaged, consider replacing the entire pump instead of rebuilding it.
- Reassembly:
- Lubricate all new seals and O-rings from the power steering pump rebuild kit with power steering fluid.
- Install the new seals and O-rings in their proper locations.
- Reassemble the internal components in the reverse order of disassembly. Refer to your repair manual or reference photos.
- Install the rear cover of the pump.
- Reinstall the reservoir (if applicable) onto the pump housing.
- Reinstall the pulley onto the pump shaft.
- Testing (Optional):
- If possible, test the rebuilt pump on a bench tester to check for leaks and proper operation.
- Installation:
- Install the rebuilt power steering pump back into the vehicle.
- Secure the pump to the engine bracket with the mounting bolts.
- Reconnect the high-pressure hose and the return hose.
- Reinstall the drive belt onto the power steering pump pulley.
- Fill the power steering fluid reservoir with the correct type of fluid.
- Bleed the power steering system by turning the steering wheel from lock to lock several times with the engine running.
- Check for leaks and top off the power steering fluid as needed.
Comprehending the Cost Factor: Rebuild vs. Replace
One of the biggest factors in deciding whether to rebuild or replace is cost. Let’s break down the power steering pump repair cost and replacement expenses:
Rebuilding Costs:
- Power steering pump rebuild kit: \$20 – \$100 (depending on the vehicle and quality of the kit)
- Tools: If you don’t have the necessary tools, you may need to purchase them, adding to the overall cost.
- Time: Your time is valuable. Consider the hours you’ll spend rebuilding the pump.
Replacement Costs:
- New Power Steering Pump: \$150 – \$500 (depending on the vehicle and brand)
- Remanufactured Power Steering Pump: \$100 – \$300 (often requires a core deposit)
