This is one problem I have been having with my truck. It did this before installing the leveling kit so that shouldn't have had anything to do with this. Whenever turning right it always creaks or grinds. It used to do it while turning left also but it just stopped. It also does it when going in reverse. It does it both while applying and not applying the brakes. I can't really explain the sound so I uploaded this video. Hopefully someone can help me out with this.
