Go, man go!
Go gadwhite, go!
Mine will be out tonight, come hell or high water! Everything's disconnected, sans the clutch housing bolts. The driveshaft was a bear-cat! I finally was able to pound out, gently, the universals. The bolts were on too well, just like yours.
I disconnected all of the 'c' clips on the universal's, and chose a side to start with at random.
I pounded on one side of the uni with a socket and hammer. The other side of the uni poked out. With liquid wrench spray, I was then able to remove it with a vice grip (replacement universals on standby).
Then, using the socket again went form the other side, the now smaller end, sans the cap. Pounding on that, and using liquid wrench liberally, it finally slipped out the other side. Once again using the vice grip to remove that one.
Using the same procedure, I was able to get the other two caps off as well and the universal was out!
I ruined a good socket doing it, but, the job is done and the driveshaft is out and laying on the garage floor ready for cleaning and refurbishing.
It was easy to remove the bolts now, because a socket fit the top and they broke loose with little effort! With the wrenches, and universal's in place, they would not budge and I feared for my wrenches. They were bending!!!!!
I forgot to mark the universal casting ends. Oops. I guess it'll need to be balanced now.
