Has anyone else experienced a slight drift to the right? I took my Pro4X in to tweak the alignment, after alignment check, tire swap, pressure check, truck still drifts to the right. Told by service manager that truck was within alignment specs, and that Nissan is aware of some reports of XDs drifting to the right. Apparently, but not the case here, some have steering gear boxes with "excessive play" in them, others like mine have to be set to a "secret setting" that is only available through Nissan Engineers. I told him that I would go to the forum, get the settings and get them back to him, the dealership is really getting tired of getting first hand info from me that I get on here before the dealership finds out through Nissan. Keep up the good job everyone!
