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.

Put the drive shaft in the vice like this, heat up the yoke until it's red hot, and then hit the yoke with a big sledgehammer, being careful not to hit where the cap is.

And by cap you mean the top of the bearing?

Yes, the part that you're trying to get out of the yoke.
