Time2roll has the right idea. Repacking brakes every year is a mostly a waste of time and money. And just adds to the chance that something will be done incorrectly or forgotten, leading to a failure down the road. Several people have posted of problems that occurred shortly after having the bearings repacked and brakes checked out.
I also have the EZ Lube axles on a triple axle trailer. I checked mine for the first time after 6 years and about 18,000 miles. All was fine. I simply am not going to spend the time and effort repacking 6 wheels every year. That's just a lot more work than I relish. And also unnecessary, IMO.
