I just developed this problem about a week ago: I was swerving back and forth tightly when I realized I was headed for the curb. Problem was that I couldn't steer away from it. two hands on the wheel with a real firm grip slowly got the wheel back on-center. It was then easy to swerve left, but one more attempt to go right yielded the same results.

I wanted to say more along the lines of balljoints, something caught, etc, but that just doesnt make sense, because low-speed steering is still done with ease.

My guess would either be the steering box itself or the PS pump. I THOUGHT that the PS pump just pressurized the box, so in that case, I don't see why it would "seize up" in only one direction.

Any ideas on what this could be? I'm confused!

TIA!
