Broken gears, etc, will not stop it from being manually ejected. It may be so frozen that part of it is in a different stage than the other. At this point, removal is probably the only option. Honestly, even if they work, maintenance on these is very important and re-lubrication essential. Since I made this initial thread, I learned that the grease I was using was NOT a good choice, and regular white lithium is better. Most important though is that a VERY small amount of grease is needed. Very small.
