Hello Steve,
If the HappiJac Camper Jacks # LC736514-4 are binding, then per the instructions for the jacks, it may need lubrication. They say "anytime jack seems to labor more than usual, place a few drops of light oil into the oil hole in the crank socket then run the jack to distribute the oil."

Hey Steve, did adding a few drops of oil to the crank socket free up the HappiJac so the lever moves smoothly again? Your update could make it easier for the next person with the same issue.
