No, it is not automatic for the shop to clean & repack wheel bearings. Most of the bearings are pre-packed and factory sealed and you can not take them apart. You can not add more grease. Even my 1970 had sealed bearings. 1 of the bearings on the front of my KO was loose and I could tell it was dry. So I just replaced them both. Then I figured I may as well do the 3 in back too. Now I know what I am driving on have that piece of mind.
