my truck is a 2014 ram 2500 diesel with 45k miles, leveling kit, and 35 inch tires. It just started making a grinding noise coming from the front end when I turn left. It can be a hard left turn or a slight left turn and even does it when going slow. There is no play in the wheel bearing up and down or side to side. The noise completely goes away when I put the truck into 4wd hi or lo. This is what is confusing me
