Dexter's bearing maintenance information says every 12 months or 12K miles for about everything but their Nevr-Lube hubs. They also give you several recommended greases - I use Mystick which is found at any Tractor Supply store. While I fully agree with the 12K mikes, thing that every 12 months regardless is too conservative and is a Dexter CYA. As far as owning a new unit - too many tales of woe about improperly lubed bearings plus the fact that many other have had problems, including myself, with unbranded, Far East manufactured bearings. And I wont use the E-Z Lube zerks. It's not a boat trailer that needs all the grease protection possible. I just get down and dirty for a couple hours every year or so but that's my choice based on several years of military motor pool and other automotive training/work before a clean hands work life.
