The powersteering pump is making noise even with the steering wheel stationary. When I removed the cap while motor was running, I had some fluid jump out. Didn't look good. Turned off motor, added some dexron ATF to top it off, and it's much quieter. i think I need to just drain all the fluid, and also replace the lines. From the one that I can see, it looks cracked/aged. Can I just go to Autozone to source the lines? Any thoughts and/or suggestions are welcome.
