I don't know if they did, but I just did some tests of my own, because I noticed some squeaking noise while turning the wheel. I then took it home, and turned the wheel all the way right, and all the way left, each time I hit the stop points I noticed the thicker line from the power steering resevoir would jerk, and then the pump started making a loud hissing noise (I don't know if this is normal) once I let go of the wheel and it eased itself the hissing stopped immediately. I then got the car up to 40 mph on a back road, put it in neutral and cut the engine, and the steering was completely fine (I didn't know of any other way of temp. disabling power steering). It kept the car straight and didn't want to turn at all, unless of course I turned the wheel. I then hand-braked and restarted the engine, and of course the problem came back. So I am almost certain it is a power steering problem, but I'm not sure where exactly, if its the pump or the valves, or maybe even just the belt :-\ I don't know much about how the system works.
Thank you for your fast reply
