I took my truck to the dealership because of my issues and they said they had many trucks going in with the same issue but there was no fix to it. The issues popping noise heard on hard turns and/or going over speed bumps, creaking noise while turning wheel left and/or right, clicking noise heard on slow sharp turns. Also when you go over a bump the truck makes a spring loud noise to the point that the whole truck bounces. Shifter is also very hard when you try to change gears.
