Why hire a professional

I searched “best western scene” on YouTube and this is what it gave me. See what it does for you.

Maybe this will help people see the way it works

With a ez lube hub you could pump grease forever and never blow the rear seal . It will just keep coming out the front of the hub . if the rear seal isn’t sealing it doesn’t matter what you have the grease is going to leak out

There is pressure with the bearing buddy if it doesn’t have a vent hole. Then there is sprin pressure . With the ez lube there is no pressure. Once they are full the grease just keeps coming back out at you through the bleeder/vent . Every time I take my trailer somewhere I pump each hub until I see grease coming back out at me , that way I know I’m starting each trip full . Watch the first video. Each time he pumps the gun it is pushing grease to the back of the hub/axle then forcing it back out the front . These don’t get you out of maintenance but assure your axels are full of grease , plus you can flush them if you want to

These guys explain they don’t eliminate all maintenance. I like them because of the ability to flush them and the ability to fully pack the hub with grease.

The trailer I have them on is used to haul a tractor and an excavator. It has breaks . I’ve had trailer for about 15 years now and never a problem with the hubs . I’ve had to work on the breaks a couple times but never for grease . These shouldn’t leak any sooner than anything else , especially bearing buddies . There’s no pressure on the seal , it’s just a more efficient way to re pac the hub . You usually won’t find these on the small trailers , I’m guessing because of cost

If you look at higher end boat trailers they will usually have some version of this hub because they are always being backed into the water . This gives you a way to keep the hubs full of grease and the ability to flush any water out
