* Power steering pump: A seal within the pump itself could be failing, allowing fluid to escape. This is a common point of failure.
* Power steering hoses: These hoses carry the fluid throughout the system. Cracks, holes, or loose connections are frequent causes of leaks. Check carefully along their entire length, paying close attention to where they connect to the pump and the steering gear.
* Power steering rack and pinion: A leak here could be due to a failing seal or damage to the rack itself. This is often a more serious and expensive repair.
* Pressure lines: These are high-pressure lines that carry fluid from the pump to the rack and pinion. Leaks here can be dangerous.
* Return lines: These carry the fluid back to the reservoir. Leaks are usually less dangerous than pressure leaks but still require repair.
* Power steering reservoir: The reservoir itself could have a crack or a damaged seal.
To find the leak:
1. Clean the system: Thoroughly clean the power steering system with degreaser. This will help you see where the fluid is leaking from. Let it dry completely before adding more fluid.
2. Add some fluid and look closely: Add a small amount of fluid (don't overfill). Then carefully inspect all the hoses, the pump, the rack and pinion, and the reservoir while someone slowly turns the steering wheel from lock to lock. Watch carefully to see where the fluid is coming from. You might need a flashlight.
3. Use a pressure test: A professional mechanic can use a pressure test to pinpoint the leak more accurately.
Important Note: Don't drive the car if it's leaking power steering fluid. Driving without sufficient fluid can severely damage the power steering pump, which is a very expensive component to replace.
