Okay, so I have a few questions about changing the wheel bearings on the boat trailer and thought maybe some folks on the board here could help me out.

I punctured the rubber cover on one of my wheel buddies and I'm getting grease thrown all over the place as a result.

How often do you replace the bearings?

If I do one side, should I do the other side as well?

I noticed there is a 1.72 and 1.92 cover for bearing buddies are there different sized axels and bearings as well? If so, how do I know which one I have/need?

How do you determine the size of bearing buddies you need?

Thanks for any help and suggestions guys.
