Recently repacked my trailer bearings and replaced grease seals. One of the bearings had a bit of wear on them and a tiny bit of "blueing". Nothing drastic by any means and the bearings still moved freely and smothly, but something I'll likely replace the next time I repack them. My biggest fear is running down the road and having a bearing seize up on me. Do any of you guys keep a set of grease packed bearings in your boat for such an emergency? If so, do you just keep the pair of bearings on board or do you also keep the races handy? i guess my question is if the bearings do seize up can you just replace the bearings to get you home/to the ramp or would the reaces also need replaced? Obviously everything would be replaced once home. I can see something like this ruining my day REAL fast!!
