[s-cars] Power Steering Failure?

[Paul Park]

Hi guys,

as many of you know, the past weekend brought a lot of heavy snow. SO
much so that it was easy to get high centered. I had to drive quite a
bit in the weather, and I attributed the heavy steering feel at slow
speeds due to the packed snow.

Well the roads are fairly clear, and I notice that at rolling speeds
above 3-5mph, my steering is very effortless. It's never been so easy
to steer the car. I cannot, however, move my wheels at all when the car
is at a complete stop. So I guess it's not the Power steering pump?
When trying to turn the wheel at slow speeds, the car makes a whining
noise up front, and the wheel shakes.

Any help, or diagnosis?

Thanks,
Paul
