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.
It’s not going to push the seal out of the hub. It can and will push the grease past the lip of the seal though.
This maybe why the staunch recommendations to not use this, as many don’t understand what’s going on in the hubs.
This I can see as more likely to happen, but after you do it a few times you should know how much grease it takes to get it right? If you add more then that then it has to be going somewhere else. Its not a closed system, so if its not pushing out the front, then you have to take it apart and look. I think the biggest problem is people dont rotate the wheels when pumping in the grease. So it builds up in one spot.
