I have a “bearing buddy” equipped hub. What is the correct way to add grease?
Bearing buddy-type grease caps are usually clear plastic so the grease level is visible. They are designed to be used in a “captive lubricant” hub assembly. Bearing buddies provide a grease fitting for the purpose of topping off the lubricant. Add grease whenever the sight disc drops below the marked minimum fill line. However, the only way to eliminate contaminated grease is to remove the hub and perform a complete cleaning, inspection, and repacking of the bearings. Always replace the inner seals and outer retainer when performing this procedure.
