About couple of months ago I had an inner bearing go out on my trailer and it pushed the whole hub and wheel off the spindel and dumped my boat in front of the house just as I was backing it up the gravel drive. We jacked it up but a new hub on it and took it to the repair place. Had the boat lifted and stored so they could work on the trailer. The spindel was still intact but it had a little bit of scoring on it where the hub rubbed on it. The repair shop suggested that instead of replacing the spindel that they could maching down the scoring and make it all smooth again. Saved me some money in the process. Well I just noticed today as I was hooking the boat a little spot of grease on the hull over the wheel. looked under there and there was a little bit of slung grease around the inside of the wheel. It wasn't by any means covered completely but enough to peg my curiousity. So I wipped it clean and i'm going to see if its leaking tomorrow after a test pull. It just makes me think I wish I would have spent the extra money and got the spindel replaced. Unless its just excess grease cause I just re-greased the hubs with a gun.
