So I'm posting this for a buddy... 2008 f350 just got new toyo at's a month ago. About a few days ago he noticed that the steering is fairly unresponsive and when changing lanes on the highway it's almost like the rear end feels sloppy and doesn't want to follow the truck. Even a slight lane change makes it feel like the back end wants to kick out. No vibrations, not lifted or leveled, all stock suspension and steering parts. Lugs are torqued to spec and we aren't sure what is causing this issue. Any ideas?
