That does not sound normal. You might want to check the upper/lower bearings/bushings in the steering column. Also, look for some idler arm & pitman arm interference with the car sitting just to be sure.

It almost sounds like a "bumpsteer" situation, so you might want to check your alignment too. Has the car been lowered?
