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.
GREASE GUNS EXPLAINED
"A high-pressure manual grease gun is designed to deliver from 2,000 to 15,000 psi. Applying too much pressure while greasing will damage the bearing seals, which rarely handle more than 500 psi."
Should be a "no brainer" since even the cheapest of the cheapest grease guns will easily develop more than 500 PSI. Some guns may have an adjustable relief valve but that would require calibration.
