Steering slop

So I'm wondering if this is normal or if something is out of whack. If I jack the front of my car up, and grab the driver's side wheel at 3 and 9 o'clock, I can make the wheel move in and out without the pitman arm moving, the only thing that moves is the centerlink rotates on the pitman arm and the idler arm. So if you were to look at the centerlink from the end, it rotates. But this allows the driver's side wheel to move independently of the passenger side wheel. I'm wondering if I need a new pitman/idler arm, or if this is what it is. And yes, new parts all around, with about 10,000 miles on them.
