The easiest way to fill your bearing hub or disc rotor with grease is via the use of a grease gun. Always use high-quality grease to help prevent bearing failures.
Warning: Overfilling a hub will cause excess grease to be expelled via the rear bearing seal. As a result, the grease will splatter on the inside of your rim.
This expelled grease is impossible to clean from your wheel unless the grease is cleaned off immediately.
Note: Bearing Buddies are not recommended for electric drum brakes.
