Here are some pictures of a disassembled 1954 Chevrolet 1/2 ton U-Joint.
The bearings used I believe are of the Granodized type.
Pic A Pic B Pic C Pic D Pic E Pic F Pic G Pic H What is interesting the rear yoke bearing (ring) not only moves on the trunnion surface, but also on the rear yoke hole surface.
On both sides of the bearing there is movement.
Unless the lock ring keep the bearing from moving inside the rear yoke hole.
Isn't the rear bearing suppose to be pressed into the rear yoke hole with no movement? (tight fit)
On the front yoke bearing (winged) there is only movement on the trunnion surface and inside surface of the bearing.
The other side is fixed and bolted to the front yoke.
