Somebody knows the answer

Finally getting to fixing the leak in my power steering ram and its stuck. I've done this job before and it was easy to remove the ram from the engine (volvo 5.7 gsi, 1998). There are two cotter pin secured pins in the end of the ram that attach it to the drive's steering arm. One is stuck. I've soaked it in blaster, used a c-clamp like a press to push it out of the hole, hit it with a hammer, cussed a lot, still stuck. The steering arm that the pin goes through moves freely, so the stuckness must be where the stainless pin goes through the aluminum housing of the ram( a great place for corrosion) I've always kept the area well treated with corrosion block and don't see any sign of corrosion at all, but it does get salt water on it.

Any suggestions?
