This just started about a month ago (got the truck back in May). Anytime I'm stopped and just turn the wheel a little bit back and forth, like within the "play" range, I hear a strange thump and feel it on the floorboard. It doesn't matter if the brakes are applied or if the truck is in park, it still happens. Before I take it to the dealership, does anyone have any idea what could be causing this?
Thanks, John
