Ok, so i have the ez lube axels or whatever they are called now. I will use them after i finish my break job. I really dont see how a normal hand pumped grease gun will push out the back seal. Hell, i have a hard enough time trying to pry out the rear seal with a hammer to repack them. The new seal is always tight goung in also. I can see if you re use an old seal, or dont put the seal in correctly that you might blow out the rear seal. But under normal operation. I cant see it happening. Now with that said, i would repack by hand every 5 years or so to check the bearings and races and such. But i plan on using the ez lubes for a few years for annual greasing after its set up.

Do you understand that somebody that does not know what they are doing with a hand pump grease gun can tighten the tracks on a D-6 Cat dozer so tight it will not hardly pull up on a trailer?

Which is the "conventional wisdom" that my Dad taught me back when I got my first car and he showed and explained step by step on how to repack the bearings.. Big rule was to not pack the hub center full of grease. Just pack grease around all of the bearing surfaces is sufficient.. Has worked well for me for several million miles of driving across multiple cars and trucks.

But I get it, not everyone likes to get hands dirty and grabbing a grease gun is very convenient..

Thank you
