I know its in the rear somewhere, pretty sure its in the rear end. It makes a clanking noise when I drive slow and make a turn. I think when they installed the gears they put too much of a gap between the gears. Anyone have any suggestions on what it could be or how to fix it.

 

Is it only doing it when you turn? If so it sounds like it's aratchet type LS/locker. It has little gear type things that will "break free" when the tires need to spin at different speeds. I would assume you'll hear it more at lower speeds because there isn't as much other noise to drown it out and it's a "slower" action that may clank a little more.
