Words they mean a lot sometimes. In this case there is generic versus specific. In the first post Michael used the words bearing buddy likely because he heard it from the service person at the shop.
And in reality there are serveral types of non-standard wheel bearing lubrication systems as stated in this thread.
Easy Lube spindles
Never lube bearings
Aftermarket Bearing buddies that are not part of a replacement axle system
And may be others
While these are specific marketing names for different systems and the manufacturer would like us (the consumer) to adapt that term as the only thing acceptable the consumer could use the term generically and not know what system is actually on the trailer.
Great thread!!!! Michael, Thanks for reporting exactly what you did have as there are many users that would have figured out what exactly was on the trailer and never posted the last time.
