Trying to diagnose the exact problem with my 05 Chevy Uplander power steering.
- Just started making that “whirring” noise yesterday while the vehicle is running, and the noise is worse (louder) when turning.
- Fluid level was low, and it looked frothy or bubbly when I opened up the reservoir.
- Topped off fluid today, and the noise is gone while vehicle is idling, but still makes noise when I turn the wheels.
- Appears to be some fluid leaked onto what I believe is the return line hose where it goes into the pump. (it is higher up on the pump and has a rubber section with ear clamps connecting it)
So, is the return line my problem? Any further diagnosis that I should be doing to narrow it down?
Thanks for any thoughts.
