E-Z Lube completely packs the volume inside the hub assembly under some pressure, which is certainly vastly more than necessary, but at least establishes that it could not be possible to manually over-fill the hub with grease.
On the other hand, it is certainly possible to adjust the bearings too tight, and to improperly seat the bearings which causes them to loosen up with use.
