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...
Bearing Buddies are for axles that go underwater....The theory is that the grease is pumped in pushing against the spring in the cap. The spring keeps the hub pressurized and keeps the water from getting inside.
The short answer is "No".
The only way grease will get into your bearings is IF you blow the seal out out of the hub and the grease can flow through.
No way I would make that trip without packing the bearings!
