How to jack a steel post out of the ground

materials

Following on from this and this question I've got to the point where I am trying to "jack" a pole out of the ground.

I had a spare 3/4" bolt that I thought would be strong enough but unfortunately it bent (see image).

My question: What commonly available (i.e. I can buy it from one of Home Depot or Lowes) 10" x 3/4" rod can I get that will work here? Or what else would you suggest to achieve this goal?

I would use a chain and make sure it is bolted to the post so that the link is touching the post, (both sides ) I.E. threaded bolt through the link with a nut and washer holding it tight to the post. Do this on both sides of the post so you create a loop for the jack to pull up on. You may want to rent a hydraulic post puller.
