OK, from looking at the threads, I think I might have the "O" ring problem. If someone would please verify, I'd appreciate it. Here are the symptoms:

For a while now when I am turning into a parking space it seems like the power assist is not working or is very weak. This has been happening for a few months. Recently, when the steering is under load (slowly turning the wheel left and right), but without the car in motion, it will "whine" and groan like the fluid is low. The fluid level is correct, so I was thinking the pump was bad. It does not happen when the wheels are pointed straight. Does this sound like the "O" ring problem? Thanks.
