11. For the rear axle, we went with the full-floating option. If on the off chance we blow a shaft, we want to be able to pull it and limp the Jeep home on one. You can see the back side of where the brakes mount with the JK-spec wheel sensor mounts. Also notice the spindle is both butt- and rosette-welded to the tubes. The rosette weld is the telltale sign that the spindle is machined for the ID of the axletube and slips inside it about 2 inches. That makes for a much stronger end than just butt-welding it together.
