Hi Ted,
The screw will not come completely out of the inner tube. It is built this way so you cannot overextend the jacks resulting in complete failure.
What I did with mine was I put my cordless drill onto the top end of the screw, and then grabbed handfulls of grease and held my hand with grease around the screw while I ran the screw back and forth into the inner tube and greased and greased and greased it.
If you are trying to remove the threaded rod top from the outer tube you have to remove the 3/16 by about 3/4 inch pin that is underneath the gear. It can sometimes be hard to see if there is grease there. Even a bit tricky to get it back into place upon attempting reassembly. Watch the instructions in great detail in the pictures.

Ditto this!!!
Some use water proof bearing grease...
