I have a ranger trail trailer with Vault hubs. It's a 2012 and from the best I can tell they recommend maintenance after 10 yrs or so. I don't travel long distances very often and basically just a weekend warrior type guy. My question is have you, or do you recommend, maybe taking it in somewhere for a look over and maintenance with hubs or anything I might be forgetting? Should I just keep trucking along and monitor stuff periodically for what I perceive as a problem. Thanks in advance.
