65 Valiant Ball and Trunnion Question

Hi all, well the trunnion is definitely worn! I took it apart and it looks like a piece of the cap broke off. Looks like the grease inside dried up and it got very hot. I was careful to only use a small amount of grease when rebuilding the shaft not to throw off the balance, I believe Chrysler recommended an ounce of grease at the most. I just use conventional wheel bearing grease, was this incorrect? The play isn't too bad but in one spot the trunnion really has a lot of slop. I can feel on the inside of the trunnion a ball shaped spot that wore away. See pics for more info, you can see a piece of the ball cap also broke off.
