Cummins, no I have not because I don't have the zerks, know that it is the wrong thing to do, and have known for years that it came from the boat industry. RV forums have any number of posts about people who have done it.
Go ahead and recommend it if you like. It is simply the wrong thing to do.
Porthole, "The clean and repack every year is over kill if it was done properly in the first place" while I agree with what you said, most RV forums will return a veritable myriad of replies saying otherwise.
