How many "repairs" in 60 years? Who knows. The U- joint and bushing in the tube are new. I checked with the truck on jack stands under the axle. And a floor jack under the tube. Pulled the bell back. transmission fluid drained from the bell. About a cup. The U-joint was still snug in it's home all bolts and clamps looked good. When one rear wheel was turned by hand the U-joint was smooth and tight. The transmission was making the click/clunk noise. Only thought I have...when the bushing was replaced in the torque tube it was tight. The U-joint slip onto the drive shaft was tight. I may have put some pressure on the yoke in the transmission that has caused the output shaft bearing to fail. The process of putting the U-joint back together was tough with almost no clearance between the drive shaft and the transmission. I lifted the transmission to get the room I need to get the U=joint back together. Was as if the drive line was too long. After the U-joint was in place I lowered both the tube and transmission until the rear mounts were supporting the engine and transmission. Then I pushed the U-joint fully into the yoke and secured it. Might have been a 1/4 inch. I never gave it a moment of thought.I would bet it has to move on the drive shaft more than that. So now I get to pull it apart and fix the bearing and whatever else the metal from it has done. Good news is I have a donor transmission that is in good shape. I have come to suspect the truck is a "bitsa" truck. A little bit of this truck, and a little bit of that one over there. Hense the early axle on the back, the later one on the front. And a 235 to go. All in 1 1952 1/2 ton. Oh there is an alternator and a 12 volt regulator on it as well. But, a 6 volt starter...go figure.
