Good info. I put the same kind of seals back in {new ones not the old ones, lol} that have lasted for over ten years. I know now that the "Buddy Bearings" and my overfill caused the problem not the seals. I think next year I will go back to my chrome cones and take off the "Buddy Bearings" save them for backup on the boat trailer.
But what gets me is that I see alot of the new trailers that came with that instalation on the hubs. They must have the kit that those auto lube guys sale already installed. Which is a heavier seal,a stainless sleeve, and "O" ring. Some have the spindles drilled out so the back bearing gets lube through the channel.
Anyway thanks.
