Hi guys,
If I'm not mistaken, there is a difference between the 1937 U-joint for a three-speed and that for a 4-speed transmission. I too have the 4-speed in my 37 1/2 ton, and at first I tried to follow the directions in the service manual, etc., but eventually came to the conclusion that this information really didn't apply to the U-joint on my truck. In the end, I took out my transmission twice!?!?!? for reasons I won't go into now; the first time, I pulled it when I pulled the engine, through the front. The second time, I pulled it from the rear by releasing the axles from the springs, etc., and pulling the tree (third member) backwards.
The point is that the 4-speed U-joint doesn't come apart the way that the 3-speed U-joint does. I, like Kevin, could not get it apart after pulling the clips; it does not have bolts and does not seem to be able to be driven apart (even on the bench after being taken out of the truck).
Long story short--the transmission has been in there for several years now, working beautifully. If I didn't need to detach the springs, the brake lines, etc., and pull the third member, I feel really stupid. But for the life of me, I couldn't figure out how to get the thing out otherwise. It's my guess that you'll have to pull it from the rear.
Good luck,
Jim
