I stopped by the parts dealer for Tracker last weekend as I happened to be in the area and wanted to pick up a spare hub with bearings kit. I probably average around 2500 to 3500 miles per year on it. So far, everything still seems as tight as it did when it was new. I have always kept my bearings full of grease and always jack it up once a year to check for play or wobble or noise. Just stumbled onto this site and looks like a great site! I probably have been lucky but I have a 2003 Trailstar trailer matched to my 185 Tracker that I bought new in 2003.
