Just has C-Clips, thats all. Plenty of axle, plenty of splines, but if one of them C-clips finds its way out, (which is unlikely, since the clearances are pretty tight in those axles) then out she comes. I have seen the result of a C-Clip getting out. It tore things up pretty good inside the carrier. To the point that they had to replace the carrier and spider gears, as well as the C-Clip of course. It was a 10 bolt Chevy axle though. C-clip eliminaters are cheap insurance.
