My trailer had a hub leak I noticed shortly after I bought it. Took it apart and found that there was some pitting on the spindle right where the rear seal is. (probly water intrusion that sat there) Im wondering if JB Weld can be used to fill the gaps or if i should just buy a new spindle. I drove 2000 miles after buying the boat and the bearings still looked brand new when I took it apart. Just kept pumpin grease in it.
