GM used a grease whereas FORD used oil (to 1957). It seems the grease GM used turned out to be caustic and formulation changed for their 57 model run. Possibly FORD recognized the GM problem and developed their own spec grease for the 1958 model run (recirculating ball type)?
Possibly also, FORD went to a grease (58) as a result of failure to retain oil in the box? The type of grease specified was not chassis grease, but a grease that would coat and stay with the internal components.
There is most likely a SERVICE LETTER of that period covering this situation.
FORD stayed with that grease (type) until box production end (1979?).
After reading so many pages/sources, I am inclined to believe the earlier oil filled units should use grease, properly sealed of course.
