Pedestal Stuck ZX 250

My rear seat pedestal is stuck in my Skeeter ZX 250. I can turn it with a pipe wrench but it does not back out. Anyone have any idea how to get that son of a gun removed? I'm somewhat concerned I can turn it but it doesn't back out. I don't remember if the post is threaded as I have four or five pedestals.

Liquid Wrench??

some thread in, some don't. They will rust and get stuck over time. spray with pb blaster or similar, just being careful of staining the carpet. Keep working it back and forth.

Yep hopefully some penetrating lube will help (I like Kroil), rust is the issue I bet.
Might try to pull it with and rotate it, I could see connecting a slide hammer thru a drilled hole

I had an old boat that the pedestals were stuck on. Wrapped a strap wound them and over a support so i could put some pressure on them, put lube on them and worked them back and forth till they came out. Keep pressure on them with the ratchet straps.
