Front axle hubs

[castro0724]

On my front hubs each side has a plug that screws into the back of the hub and in each plug there is a grease fitting that is screwed into the plug. My question is do you unscrew the plug and then add oil or grease and if so, what kind and type of oil or grease or do you just service it with grease using the grease fitting. Thanks
