I'm not sure that lubrication was the problem as much as weak U-joint bushings. As I said, although there was not a lot of lube in the cavity when I opened it up, the U-joint seemed plenty moist with lube. In both of my U-joint failures, the U-joint failed when one bushing disintegrated, although the remaining bushings were very loose showing a lot of wear. Hopefully, Mac's NOS Ford U-joints will be better.
