leaking grease seal.
So the Tt has a hub leaking grease. going to take it to MM trucking in Lincolnton NC to get it fixed. According to them. They will more than likely have to do the brakes on that hub as well. Make sens...

I have no experience with axles that have the zerk. I can see how it would be easy to push grease past a seal, or even push a seal out. After all, a hand grease gun pushing grease is used to tighten the tracks on a loader.
But I have worked on lots of things. Many seals fail because of bad installation. That kind of thing happens shortly after put in service. If it has worked for a while, from a rock crusher to trailer to little bearings on antique motors, if a seal where a shaft spins, or something spins on a shaft, there is a bad bearing. Now did the bad bearing let things wobble ruin the bearing? Or did the escaped lube let the bearing get too dry? No matter, they fail together.
Now when you add the zerk, and grease pumped in the bearings could still be good.
