When do u guys repack trailer grease
I blew a hub south of Devils Lake at 2am once. After removing the tire and hub so as to take it to town for parts and repacking, I seriously considered lighting my boat on fire, rather than go back and face those mosquitoes again. Ever since then I am a stickler about my hubs.
I repack mine every other year. In and out of water is tough on grease. Main concerns is the oil/grease seal on the inside of the hub...ya gotta crawl under there and look once in a while as this is the main spot where water will get in.
Buy good bearings and races. Buy good marine grease. Use Bearing Buddies. I only use Timken bearings and Lucas grease, and repack them every 2 years. This year was number 10 and I didn't dare use them again, even though they looked fine.
When you stop, check the temperature of the hub with your hand. The temperature of your hub should never get warmer than the sidewall of your tire. So on a cloudy day and the sun not beating on your sidewall, your hub should be at about the same temperature at the outside air.
Traveling with a spar set of bearings and grease, along with knowing how to repack bearings, remove and install races and seals, is just a good set of skills to have if you pull your boat a lot. Eventually you will have a hub failure. Lots of good videos on YouTube.
