A couple things I saw that are different from the comments on this post.
My screw sections are lubricated with oil. Oil would get there from the hole in the socket. It wouldn't lube the grease pocket or other failure points, but it would lube the acme screw.
There was a large o-ring between the square plate and the round piece that contains the needle bearing. On my jack it had broken up, and I think that was the cause of the vibration that caused me to tear into it in the first place. I've viewed several postings/blogs/photo links on Happijacs, and I've never seen this mentioned.
