After all I've done to rebuild the front axle on mine, there's still a fair amount of noise in 4x4, so suspecting the drive shaft (and needing to get it out of the way to repair the trans shift linkage that had popped a head off the screw into the frame) I took it off, the axle now runs near silent. The driveshaft looks terrible, I bet it's well out of balance with the amount of rust on it, and the boot over the ball joint in the middle of the double cardan has split. The u-joints are far stiffer than they should be.

So what's the trick to getting these joints apart? After soaking the caps on penetrating oil for a week I'm able to press the joints through the yokes, but this shaft has the Spicer joints with the fat middle of the cross, and they won't push far enough any way to push the cups out of the bores. The cross hits the inside of the yoke first.

From what I'v done my self,the way I did these is soak in PB Blaster for a coule of hours.Then push one side out as far as it will go,then use a big pair of channel locks or vice grips turn back and forth and pull at the same time.they usually pop out.If they don't a little map gas on the yoke.Hope this helps.

What I think was the problem was (apart from the mass of rust) is that the bores for the joint in the yoke on the end of the shaft that has the extension for the pin that goes into the ball joint in the middle of the cardan, is a little offcenter, effectively too close to the extension piece. I eventually did get them out, but I had to mash the joint into the yoke a little to get it far enough across to get the cap loose - I couldn't turn them pushing the joint until it came into contact with the yoke. Pics to follow, I've bead-blasted all the rust off, and I think I'll trim a little off the yoke to avoid this happening again.
