Advised not to repack bearings???
Two years ago, and with our previous trailer, we had a miserable and expensive bearing failure while 4k miles from home. At the time, we had buddy bearings and were under the impression that they did...

That is how they are designed to work. You can force grease past the rear seal, as has been noted a grease gun can create enough pressure to defeat most passive grease seals. Using an air operated grease gun on these axles will, IMO, guarantee that grease will find its way past the seals and into the brakes.
IF you pump to much grease in it will push past the seal and ruin your brakes, this is what a lot of people do, in this case more is not better. dexters work great if used right. if you pack the cavite full it,ll expand and ruin your brakes
I have to admit that I don't understand why trailer bearings supposedly need to be removed, cleaned, and inspected frequently while my car/truck wheel bearings haven't been touched in hundreds of thousands of miles and still work. They both use Timkin-style bearings and should be good for a very, very long time.
I also don't know why the EZ Lube axle is necessary for a trailer that doesn't see regular immersion in water.
I have worked with large equipment that use Timkin-style bearings on large diameter shafts and flywheels. These often run 24/7 for a year between servicings, and do very well.
Is it the side loads on trailer wheel bearings, poor quality bearings, or some other issue?
