Abstract: A device for injecting grease into a wheel bearing avoids the need for removing the seal ring of the wheel bearing. The device has a hollow mandrel with a closed bottom. A flange extends outward from the mandrel for contact with an inner cage ring of the hearing. A collar extends radially outward from the mandrel above the flange. The collar has an outer edge for contacting the seal ring. The collar is axially movable relative to the flange. A spring urges the collar and flange apart from each other. A port is located in the mandrel between the collar and the flange. A grease fitting allows grease to be introduced into the mandrel to flow out the port, into the space between the collar and the flange, and into the wheel bearing.
