I'll take an order of maxglide directly into the jacks please...
but only after lubricating the main rails and jack guide "rails" with 10w30 motor oil. I use a goldenrod oil can. Best stuff for those I've found. Slip it's great too but hard to source and a pita to apply. Synthetic motor oil works very well.
If a good oiling doesnt fix it, I'd land it, pull the drain plug on top of the jack blow some compressed air to push some oil into the tank to create room then add a half gallon of maxglide at least to each jack and dump a gallon in the tank.
