I've been fighting this too, I went so far as to take off my lift and flip kit and spacers, I was just convinced it was some aftermarket part I had put on. I had tried to lay underneath and watch as the steering wheel was turned and saw nothing. Pried up and down on the wheel to check ball joints and saw nothing. I finally tore it all apart and my lower ball joint on the passenger side was shot. 13,500 miles all on stock wheels and tires. I'm in the process of changing ball joints so I don't know yet if this will 100% fix it
