My power steering has a leak. How do I know if its the hose or pump?? on 1999 Toyota Corolla

The only thing that stops the grinding sound is to add power steering fluid. It lasts for about two weeks and then the noise comes back.

A good cleaning and adding leak detection dye will prove beneficial. Messy, oily engine components are hard to find leaks in. Call around you local area and see if a reputable shop can help with this service.
