Ok yesterday my dad comes by to pick up the boat to take to La to fish this week....(I will be headed down Wednesday but that not my problem). As I was putting grease into the hub.....the little nipple that the grease gun fits into broke off. So I need to know what I will need to replace. Will I need a new hub all together? Thanks for the help guys, the tire is 13" if that makes helps and no trailer brakes.
