If i recall correctly the orginal ball bearing isn't sealed on either side, so the 90W from the diff eventually washes away the packed grease. i figure the bearing wears slightly, then the seal (in the housing) is slightly compromised and so lube gradually mixes into the bearing
Groove is where the housing seal rides
Grease packing
These replacements for the small bearings (1970-1972) are sealed on one side. The other side goes up against the brake backing plate so that's good - assuming they are installed with the seal facing in. They still gotta be packed but i reckon the grease will stay put for longer
