There's not enough information in your question to provide an accurate answer. There are many things that can leak. Power steering pump, hose connections, hoses, rack and pinion..... All of those things have seals and now that your vehicle is about 10 years old some of those seals may be failing. If you haven't located the leak and have just noticed hydraulic fluid on the ground I'd suggest you clean the pump, hoses and steering rack thorougly with a spray degreaser then run the engine and turn the steering lock to lock. Turn off the engine and trace the system back starting with the rack then checking hoses and ending at the pump. Cheers
Clean the power steering are real good check for where the leak is coming from and go from there. For example if a hose is leaking replace hose, if power steering pump seals are leaking replace pump, exc.
