I test drove a 95 Legacy, 2.2L engine. The power steering fluid was almost empty. I pulled into a parking spot, then when I went to back out, there was a strange moaning noise from the steering rack and the car didn't want to turn at all for a few seconds. Then it was fine. has anyone else ever heard of such a thing? Thanks.

to keep fluid in any hydraulic system. They make a lot of noise and don't work otherwise. Find and repair the leak if possible, if not keep it full.

This wasn't a normal power steering problem. I've never seen a rack lock up or bind then be okay again. In my experience, it either works right or it doesn't. Maybe it was the AWD instead...because it didn't match normal ps rack behavior.

usually you just get greatly increased effort. I think I would want to inspect this car on a rack and see if I saw anything binding after that.Shut off the engine and turn the car without assist and see what it feels like.
