Happijac lubrication

Thanks, Bigfootford. I didn't know the proper terminology. The swivel to which I refer is perhaps called a centering block. It is internal to the black tube and is attached to the bottom of the acme screw. one of the members used a band saw to cut the black tube apart and the picture of this part shows excessive rust. I only intended to explain how I delivered hypoid oil to this part. My jack was binding, but from what I could see everything appeared to be well lubed. I did what I could to lube that which I could not see and now the problem is solved. I will try to be more accurate in the future and also to have pictures and illustrations as well.
