I'm an avid do-it-yourselfer but have never repacked axle bearings. Since I'm planning on keeping this trailer for a very long time and have heard stories of bearings being short on grease from the factory sometimes; I would like to get this done. Is this something I should be able to do myself over a weekend day? I've pulled up a couple of videos and most seem to show someone using a machine to force grease into the bearings. I apologize if this is a really novice question, but I'd rather do myself if possible.
