I have to get a pair of channel locks and rags to twist the pole and get someone to pull up on the seats to get them out. As soon as I put them back, the same thing getting them out. They are the original posts and I even purchased a new one to see if that would help. I was thinking of cutting the plastic insert out of the base but I think it would wobble then. Any suggestions on how to fix this. The posts are the kind that are not reduced on the insert and have the little lock down on the bottom. The lockdown isnt the problem, I can push the button and release it, just cant get the post pulled up and out and have to use channel locks to even turn the pedestal. It is on both the front and rear seats too.
