Well, end of the line for my attempt to repair/ maintain the problem jack. The instructions were relatively easy. Getting th gear out was a little tough- I ended up attaching a needle-nose vice grip and then gently tapped the steel outside shaft and the gear popped off:


Once I got the gear off I thought I was home free to complete the chore...
But... the bottom leg would not extract from the housing! I think there was so much rust inside and it wedged between the inside of the outer shaft and outside of the inner shaft. There were deep scores in the paint of the inner shaft clear to the steel:

I tried tapping the lower leg out with a hammer to no success. Then I got a bigger persuader but it started to really tear up the foot pad:


I figured if I could at least get the jack apart I can weld up a new pad so I keep on pounding. But in all of the banging I only budged the lower leg about 9"... whatever is bound up inside will no longer allow it to move. At one pint I had already resigned myself that I will be buying a pair but I wanted to get this dang thing apart to see the inerds.
Who has the best prices on jacks?
