I have a 2008 Keystone Raptor 3110TT. It's been a super awesome trailer...of course we maintain it to the hilt to keep it nice. Also, it's always been stored inside my garage since new. My questi...
You can only pump so much grease into a bearing until it is too full. If too full the bearing will run hot. Personally I would rather take the bearings apart every 10 years and re grease them. Greased bearings last 100 thousand miles easy a trailer is no differrent. Unless, from new it wasn't greased enough.
