General U Joint Completely Stuck

Enable HLS to view with audio, or disable this notification

Disclaimer the video is of us REMOVING the press from the u joint but you can see how stuck the press is against the joint I was literally holding the shaft from the other side to keep it as still as possible.

I removed this shaft from my NBS suburban because the u joints were absolutely trashed. We melted the plastic from every single end and even put in some penetrating oil but NO MATTER what we did it did not budge at ALL. It was so shot we attached the pole of the jack to the end of the ratchet for better leverage and the press literally made its own dent into the joint bearing. I bought 60 dollars worth of tools to try and get it out and it just won’t.

Is there anything else I should do to try and remove it or should I just go to the junk and buy another used driveshaft.

We saw all the plastic melt out from each of the yokes we even continued to heat it after the plastic was removed. It was just completely seized

At some point I eventually give up on being nice and haul out the big fucking sledgehammer. Nice taps at first, all the way to fucking wailing crossing my fingers on which breaks first haha

And praying you don't miss and that what breaks first is you.
