yesterday on the trails my hub bearing on the right side blew. the wheel was about 45 degrees in towards the fenders and i had to flat bed tow it home. today, i picked a new one up from discount auto parts and when i installed it, it makes a clicking sound when rolling. I think it comes greased already. I bought the bearings already pressed in and the hub. Is there a way i can grease this if it does not come greased? any ideas whats going on?
