Why Does One Bearing Buddy BB1980A Fall Out of Hub

Question:

I bought replacement hubs for my boat a few years ago. I can’t seem to keep a bearings buddy on for any trip to the lake. What is wrong here? I’m assuming you have record of what you sold me. Keep in mind one side that I bought from you is fine one is not.

Hi Jeff; so there are quite a few potential issues that could lead just one of the Bearing Buddy Bearing Protectors # BB1980A to fall out of the hub while the other is just fine. Per the manufacturer, one is if the spindle nut isn't torqued right or the suspension/tire is out of balance on that side the wheel will have excessive movement leading to the Bearing Buddy falling out.

Or it could be the shoulder of the Bearing Buddy got worn down if it was removed and installed quite a bit. Finally it may be if during the trailer production a spindle wasn't put on properly or is a bit different and is a bit longer than the other. This can cause the cotter pin to push against the Bearing Buddy and make it fall out.
