There's a plate on the top of the power steering box with two screws, you need to BARELY loosen them and slide it up (towards the rear of the car) or down (towards the front of the car) to correct that problem. I say barely because if you loosen them very much, you'll dump fluid everywhere.

I don't have a pic of it but someone will probably post one. If you do this with the front wheels up in the air and the engine running, you can see when you've fixed the problem, just be careful.
