It would be simple to set the yoke up in a lathe and machine the OD down about 1/8", then fabricate a sleeve to press over it. I'd suggest using a piece of stainless steel tubing for the sleeve and machine and finish-grind it to the proper OD after it's pressed on. That repair should outlast the rest of the truck with no wear concerns. Drop me a PM and I'll be glad to do that for you if you like.
