Just an update on my attempt to get a bearing rebuilt kit for my trailer idler hub prior to pulling the hub and removing the bearings, seal and race. I called Tracker and they said to contact dealer. I called the dealer and they said documentation of the trailstar trailers only goes back to 2006. So I guess my only option is to pull out the hub guts and hopefully there are numbers on the parts, or result to measuring. Fortunately replacing the bearings is not urgent. I thought this would have been an easy project, so I am going to wait until end of my boating and fishing season then pull the hubs, that way I don't miss any water time this season in case I have a hard time getting parts. The boat and trailer have always been stored in a garage since I purchased new in 2005 so no issue putting it on jack stands to work on the hubs if I don't get to it until winter. Once the hubs are off I can measure the spindle too. If needed, I could probably replace the entire hub once I have the spindle measurements and bearing sizes. Thanks for the input 92 Nitro 190dc Owner and olefisherman456. I will plan to post a picture(s) of my boat and setup on the other forum.
