The popping doesn't mean grease is going out the rear seal. Whatever gave you that idea? Grease going past a seal won't make noise. The popping will be the grease collapsing air bubbles, just means the grease is filling the open areas. IMO most of the time grease gets past the rear seal is because the hub seal surface is damaged, or the seal lip is damaged, most likely during assembly.

I stop when I can see grease coming out.

Curious , grease coming out ?? Coming out of the Axle cap ??. Never used that feature on mine, have always done them the old fashioned way by hand.

Those bearings will only take so much grease , so where after time is that grease going. I assume all its doing is pushing out the old grease, that old grease is filling up whatever space is in there. Have to believe thats where some get in trouble with grease on the brakes ???

The EZLube has a drilled spindle. It is drilled from the outboard end to the area between the grease seal and the inboard bearing, then drilled radially to the surface of the spindle. The outboard end has a grease zerk. When you pump grease through the zerk, it follows the drilled channel to the void between the seal and inboard bearing, through/around the bearing rollers, through the void in the hub between the bearings, through the outboard bearing, and you will see the older grease pushed out around the rollers of the outboard bearing.
