Why Does My Replaced Power Steering Pump Still Whine?

AvatarByCarl Frisch

Replaced power steering pump still whines is a common issue faced by many car owners. This issue can be caused by a variety of factors, including worn or damaged internal components, insufficient lubrication, or air bubbles in the system. In some cases, it may also be caused by a defective power steering pump. A whining sound from the power steering pump may indicate that the fluid level is low or that the fluid is not being circulated properly. If this is the case, it may be necessary to top off the fluid and/or check the filters and hoses for any blockages. It is also possible that internal parts have become worn or damaged and need to be replaced in order to restore proper operation of the power steering system. If replacing the power steering pump does not resolve the issue, it may be necessary to take your vehicle to a qualified mechanic for further diagnosis and repair.

Automobile: Replacing the Power Steering Pump

Replacing the power steering pump in your vehicle is a relatively straightforward process that can be completed with just a few tools and supplies. Before beginning, be sure to read through all of the instructions that come with your new pump and ensure that your vehicle is securely supported. Once you are ready to begin, start by locating the power steering pump unit on your engine block and disconnecting any electrical connectors and wiring harnesses. Then, remove the bolts securing the pump to the engine block before replacing it with the new one. After connecting it to the engine block, reattach any electrical connectors and wiring harnesses you had previously disconnected. Finally, fill up the reservoir with an appropriate fluid type before starting your vehicle and checking for any leaks.

Reasons for Whining After Replacing a Power Steering Pump

If you’ve replaced your power steering pump but are still hearing a whining noise coming from it, then there are likely air bubbles trapped in your hydraulic lines. To check for air bubbles in the system, try running through a bleeding procedure to remove them. This will require you to locate each bleed valve in your system and slowly open each one while continuing to add fluid until all of the bubbles are gone. Once this is done, close off each valve one at a time while ensuring that no more bubbles appear. If you follow these steps correctly, you should be able to eliminate any whining noises coming from your power steering pump after replacement.
