I looked at the idler and it may have moved up and down slightly but looked more like it was just moving in and out with the rest.
The tires are 285s with 17 inch wheels. I also have a 4 inch lift.
I'm hoping it stops. If not, I'm probably gonna have to tear everything apart again and see if there's side to side play at the spindle.
