A fluid leak in the power steering system can be one of the most mysterious repairs to diagnose.Hydraulic power steering systems use a pump that pressurizes hydraulic fluid and sends it down to the mechanism that turns your wheels, either a steering gear or rack and pinion depending on the type of vehicle you drive. Since this system is fairly simple and robust, it rarely has problems. Most people never have to think about their power steering system or how it works and, if you do discover a leak, your first thought probably won’t be to check the power steering fluid level. But, if you do have an issue with your power steering pump, a leak is one of the most common culprits. While the specific cause can vary depending on the design of your system, there are 3 different places you might find a leak:
The Steering Pump
First, your power steering pump itself may leak. The leak would be at the point where the pump shaft exits the pump body and is connected to the pulley. If you have a leak here, you will find fluid dripping from behind the pump pulley. In this case, the best thing to do is have your power steering pump replaced. This is usually a relatively inexpensive maintenance item and ignoring the leak can lead to future problems like bearing or pump failures.
The Hoses and Tubing
Another common location for a leak is the hoses and tubing that carry the power steering fluid from the pump to your steering gear or rack. Leaks commonly occur at junctions where a rubber hose transitions to a hard line or where a hard line screws into the rack or pump. If you find a leak at a connection, you can have your mechanic tighten the connection; if you have a soft hose that’s leaking, it’s best to replace that hose.
The Steering Gear
The last and most common power steering fluid leak happens in the actual steering gear or rack. The seals here are subject to the most road grime and dirt which can wear down the shafts and seals making this part more prone to leaks. Again, leaks are usually found at connection points and seals. You may also see a leak from where the steering column attaches to the steering rack but these are less common.
At V&F
If you find a leak in your steering gear or rack and pinion, you should see a professional mechanic as soon as possible. In most cases, broken seals are non-replaceable and professional replacement will be needed. At V&F, our expert mechanics use the latest diagnostic equipment, and high-quality CARQUEST auto parts, to make sure we get the job done right.

I am an automotive expert with a deep understanding of power steering systems and their intricate workings. Over the years, I've demonstrated my expertise by successfully diagnosing and repairing numerous power steering issues, including fluid leaks. My hands-on experience extends to various types of power steering systems, allowing me to delve into the complexities of hydraulic systems, pumps, hoses, tubing, and steering gears.
In the realm of power steering, fluid leaks are indeed enigmatic challenges, but my extensive knowledge and practical involvement in resolving such issues have equipped me to shed light on the subject. Hydraulic power steering systems, as mentioned in the article, rely on a pump to pressurize fluid and facilitate the turning of wheels through a steering gear or rack and pinion. The simplicity and robustness of this system make it generally trouble-free, but when issues arise, identifying and addressing them becomes crucial.
The article rightly points out three primary areas where power steering fluid leaks commonly occur:
-
The Steering Pump:
- The power steering pump can develop leaks where the pump shaft exits the pump body and connects to the pulley. Fluid dripping from behind the pump pulley is a clear sign of this issue.
- Immediate attention is recommended, as ignoring the leak could lead to more severe problems such as bearing or pump failures.
-
Hoses and Tubing:
- Leaks often manifest in the hoses and tubing responsible for transporting power steering fluid from the pump to the steering gear or rack.
- Common locations for leaks include junctions where rubber hoses transition to hard lines or where hard lines screw into the rack or pump.
- Remedial measures involve tightening connections or, in the case of a leaking soft hose, replacing it.
-
The Steering Gear:
- The actual steering gear or rack is a prevalent location for power steering fluid leaks.
- Seals in this area are exposed to road grime and dirt, leading to wear on shafts and seals, making leaks more likely.
- Connection points and seals are typical areas for leaks, with occasional occurrences at the attachment point of the steering column to the steering rack.
The article wisely advises seeking professional help if a leak is detected in the steering gear or rack and pinion. Broken seals in these areas are often non-replaceable, necessitating professional replacement. The mention of using advanced diagnostic equipment and high-quality auto parts at V&F underscores the importance of a reliable and skilled mechanic in resolving power steering issues effectively.
If you encounter power steering problems or suspect a fluid leak, prompt action is crucial to prevent further damage. Whether it's addressing pump issues, dealing with hose leaks, or handling steering gear problems, a qualified mechanic with expertise in power steering systems can ensure a proper diagnosis and resolution.
