frozen u joints in yoke

[TVrebel]

I have a 71 S2 that has sat for 30 years in a warehouse in Houston TX. I want to change the u joints and I have used a torch, penetrating oil and a hammer. Nothing has worked. Any ideas?

Should we assume you are using a press and not a vice? And if so, how big a press are you using?

[jbcollier]

They are a press fit and you want to maintain that press fit.  Use a press and suitable sockets/spacers.

Take the whole trailing arm off at the rubber mounting, knock the roll pin out of the gearbox output shafts, disconnect the brake hose and hand brake cable, and you can work on the whole unit.

It can take about 4 tonnes in a press if they are badly rusted in place.

Clean out around the needle roller cup in the yoke with a small pointed wire brush in a drill, and then soak the area with WD40.

And wait for the big bang when they break free.... !!

I would be careful using too much force in the wrong way you can bend the yokes. I know I have done it! You need to make sure you are not transferring the force through the yoke.
