I would think you would be able to notice if the yoke was worn that much when you had it out. I guess you could measure it and compare to a new one. BTW, The reason I asking if the driveshaft could have gotten bent when removing the u joints was because mine were so rusted that every u joint was a real pain to get out. I ended up just replacing the driveshaft because of all the trouble I had with removing them in fear that I knocked it out of balance.
