Did you guys see where the Happijac suggested maintenance suggests a once a year full extension and retraction of the jack to redistribute the grease on the screw?
Saw that, and from the condition of my front jacks when I took them apart, I'd say it's good advice. Also, I would add that it is probably a good idea when the camper is stored to raise the jacks completely and snug them up so the O-ring at the top of the screw seals tightly. This will keep the entire acme screw sealed inside the lower leg and away from moisture that caused the rust on mine.
