1. be careful. I would carefully mask around it before giving it a shot of PB Blaster. You dont want that in your carpet, so tape it well to protect the area around it.2. To salvage the pole, if possible, take an old leather belt and wrap it around the pole, then get a 12″ (or better) pipe wrench on the belt, which will protect the pole. See if you can pull and break it free. But give the PB some time to work before you do this. And if it doesnt want to break free, before leaning on it further, you might try another shot or two and give it a chance.3. If it breaks free, you will need to twist AND pull up at the same time. Often this will do the job. If not, you can try a chisel on the bottom between the seat post and the bushing to lift it up a bit.4. If no success so far, you probably are going to wreck the post and possibly have to replace the deck bushing as well. But now you lift and twist and keep it up. It will have to eventually let go. If you get a slight crack started, stop and PB blast it again since it is now getting in to the shaft itself.5. Take some very fine emory cloth to the post pin and clean it up, or else toss it and replace. I would lubricate it. A touch of something like 2-4-c, or even paraffin (as you probably use if you have a multi-piece rod). But put something on it, and dont forget to do it regularly. I dont run at high speeds with that seat and post up anyway. Certainly adds some drag, and if the seat comes off, it is going to be painful for someone and possibly expensive. I have seen pictures where it hit the passenger and required stitches, where it hit and destroyed the engine cowl, and where it hit and wiped out the windshield and didnt do the driver any good either. By removing it frequently the problem wont happen. If you notice it getting a bit stiff to insert or remove, you have plenty of time to fix it before it seizes again.2008 Pantera Classic2014 Mercury Pro XS 200
