I can say this much about lithium grease. I took apart the WHOLE freewheel ASSEMBLY, even where they have those tiny bearings (Shimano - Raleigh Super Record 10 speed ). I used the lithium grease about 10-15 yrs ago. Recently I went to ride it and when I went to pedal, the freewheel spun (just like I was pedaling backward, but I was pedaling forward). After taking apart the freewheel I found that the two teeth (I don't know the proper term) that provide the resistance were glued down from the lithium grease. These two teeth normally spring up but were very goooey and stuck.
