No what you see is all part of the oakie bushing. They're machined with deeper grooves in the center part of the assembly, and smoother on both ends.
As far as removing it, since there's that gap in the tube, you could either drill a hole to give a punch something to push against and drive it out, or weld a tab to the bushing and hammer against that. You'll probably want to remove the crossmember and drop the torque tube down a bit to give yourself some room to swing a hammer. If you don't want to swap out the differential and torque tube, dress up those divots near the dowel hole with a fine file to be sure that they don't interfere with sealing the ball cover on.
