Bearing Buddies for a Boat Trailer with 2.308 Hub Bore

Updated 08/24/2015 | Published 08/22/2015

Question:

I have a boat trailer that measures 2.308 inside the hub. Can I use the 2.328 bubby bearing protector? I have lost both covers on the highway. Is this normal or should I look to see if there maybe an issue with the axle?

Losing grease/dust caps or bearing protectors is all too common. It usually happens when caps are not driven in properly. The spinning of the wheel and the centrifugal force then causes the caps to wiggle free and fall out.

Given that your hub bore measures 2.308 inches the best match would be a 2.328 model such as # BB2328. It will be a tight fit, which is what you want. To drive them in flush place a block of wood against the Bearing Buddy and tap the wood all around, not just in one spot, to drive in the Bearing Buddy.
