G'day Folks :)
The freewheel hubs need to be engaged at least 50miles in every 500 or once a month, so that the "oil filled" steering swivel hub upper bushes get lubricated, :) (this is done automatically with original drive flanges) as it was/is a common cause of steering wear. That is why the use of grease to stop hub seal leakage causes more harm that good, as it stops any lubricant being splashed up the small hole in the upper bush designed for that purpose.
cheers
