EZ lube spindle and bearing repack question

My own pics from the last seal replacement;

Look at all that grease flying out at high pressure...

No, the grease goes in under pressure. You don't understand the concepts of viscosity, constriction, and pressure gradients.

Any 4 year old knows you have to squeeze the ketchup bottle to get it to come out through the nozzle, and you have to squeeze harder if there's old, dried up stuff in the way.

You also ignore the empirical fact that many with EZ-Lube have experienced grease in their brakes due to it getting past the seals, even straight from the factory.

Good example. That 4 year old controls the flow, does he not? Heck, just pick up the bottle upside down and you'll squeeze a ton all over. Squeeze super hard and fast, yeah some pressure will build inside the bottle...just like it would inside the grease gun. (The GREASE GUN. Not the HUB!)

And what you'll find regarding "blown seals" are not blown out at all. They are leaking/failed seals.

Grand Design 5th wheels in particular of which I've followed for an extended period of time as I am a Grand Design owner, show no signs of any blow out occurring. Not a single one.

And AGAIN...LCI is very clear on the matter...the EZlube zerks are not used in production. They use an entirely different method to pack grease into the bearing, one of which is now fully automated.
