This boat is different then my last boat, how do I access the nipple to grease the bearings? Do i have to take the bearings out also and grease pack them? i dont even know how to get the cover off. The past owner said it is grease no oil hubs. The boat is a 2002 ranger 175vs if that helps. do i have to take a rubber mallet and work the hub cover off or take off the wheel? Thanks to anyone that can help me. i have a pic for anyone that wants to take a look.
