I have a ranger rt188 and the left trailer wheel is covered with a film of grease from the hubs. The trailer is brand new (couple months old) and I know that many hubs, not sure about Vault, have a weep hole if the hub is overfilled with grease, once it all starts warming up, that allows excessive pressurized grease to escape. Does anyone know if these ranger vault hubs work like that? Anyone else notice this? Just trying to determine if this could possibly be an overfill from the factory vs a seal leaking...which I think would be rare on a brand new hub. Thanks to all
