Okay, so the 100 semi-float MUCH different than past LC semi floaters, no? No C-clip in the diff as there's no differential cover; does this mean there is a retaining clip of sorts in the hub like the minitrucks had/have? Here are some basic steps: 1. Remove caliper, 2. Use 8mm (?) bolts to back off rotor from axle flange, 3. INSERT HERE TO REMOVE RETAINING ??? 4. Be darn careful on long side for the axle seal when splines are pulled from diff, 5. Remove shaft, 6. Pound out broken lug 7. Torque new one in 8. Reverse process. Before I start, what is #3? What/where is in there something to retain the axle? (I've never worked on anything but a FF and C-clip-in-diff-semi) Are there any additional seals with which I need to be concerned?
