1996 Dodge Ram 1500 2wd Truck Front end problems.. Any ideas?

So.. I've had this recurring problem with my truck. The front idler arm(steering link opposite the steering box attached to the frame) despite how many times I change it still has play in it. And the play in it causes a shimmy whenever I come to a stop which you can feel throughout the whole truck. I swear I've chagd the idler arm at least 4 times. Everytime getting an alignmet done afterwards. I've changed Outer tie rods, Inner tie rods.. And everytime it does it for a while, it ends up warping the passenger side brake rotor. It's too the point now where I've just given up. Let me add.. The truck does have a lift on it, but it did it even before I had the lift on it. Any ideas? Someone told me it may all be because of defective parts. But I've got idler arms from Kragen's, Auto Zone, NAPA,.. Any help would be great...
