My scissor jacks are Bal brand and they recommend periodic cleaning and lubrcating with WD-40.
3 campers ago I ruined a jack doing this wit WD-40. It became so slippery, it never held again. When weight was put on the jack, it would unwind. I had to keep the hand crank attached and keep it touching the ground to keep the jack from unwinding under a load. I NEVER got that jack to work correct again.
Since then (3 campers ago), I have never used any kind of lubricant on the cork screw part of the stabilizer jacks.
