Excellent post. Makes sense what you are saying about where a bend would take place, and assures me I'm not dealing with that issue now. My jack legs look fine so I'm more certain my problem is with the UN-greased screw.
I like what you did with the drilling of holes, but right now think I'll start with the grease on the pipe insulation. My jack is in such a bind that the first thing I have to do is get the weight off it before I try anything.
After that, I'm hoping I can turn the screw shaft enough to work the grease up into the nut. If not, I'll drill and let the oil run down into the nut.
I'm feeling a lot better about this project and will tackle it in the next couple of days. Thanks for posting the pictures.
Its most likely the worm gear, I had the same issue, and found where the threads on the long worm gear was mushroomed just slightly not allowing it to turn on the nut freely . I took to a friend at a machine shop ,and they chased the worm gear, and all was well .
They are really not made to take apart although I did, its tough to explain how ,but I was able.
At that point with the worm gear, most would just have to just replace the whole unit. Mine is not made to be able to actually replace that long worm gear. Some may , but mine is not.
No amount of grease is going to fix it if the worm gear is messed up some .
