My jacks were binding and breaking the sacrificial bolt on the cross shaft as well as tripping the breaker. I used bpounds' method of drilling holes in the tubes right above the top bracket. If you do that, be careful not to push too hard on the drill or you'll hit the screw with the drill bit. Start with a small hole and then bore it out with a larger bit. I used spray lithium grease inserting the straw into the hole and directing it up and down as I sprayed. Then, with the trailer hitched to the truck, I ran the legs up and down several times to spread the lube as best I could.
This made a huge difference in the operation of my landing gear. That said, the pipe insulation method on the video has me intrigued. I believe I will add this as a step next time I lube the landing gear.
