If there is a thread on this already I apologize, I searched and couldn’t find anything. I have a 5th gen big horn crew cab with the 6’-4” box. I’ve only had it since June and only has 2,800 miles on it. It makes a very noticeable vibration that I can feel in the gas paddle and floor when I accelerate in 4wd auto. It does not do it in 2wd. And I still need to see if it does it when in 4wd high. The odd thing is that it does it even when I’m sure it’s not engaged in 4wd. But if I have 4wd auto on it always does it. I haven’t brought it in yet, thought I’d see if anyone else has experienced this. Thanks
